Ok I finally got a password to log in WOOHOO

Now, I am trying to install the BTT SKR Mini E3 V2.0, TFT35 Touch screen, BLTouch 3 and the BTT filament runout sensor and I am having tons of problems. I was hoping someone might have the config files they would share so I can at least compare them to mine to see what I am doing wrong.

I have done this for the silent board upgrade I did and then again for the bltouch (went with th3d firmware for this one) and when doing the new board I can get it to work with the board, screen and bltouch but when I add in the filament sensor it just goes back to square one it seems. I have followed guides and checked to make sure the filament sensor items were uncommented and set properly but when I give it to the printer it just doesnt work.

Anyway. If someone has the firmware for the Ender 5 with these options I would really appreciate taking a look at it. I am at my wits end with trying to now use vscode instead of arduino plus this just not working for me....i need to take a break lol

You can post your configuration files for us, and use the code tags by copy/pasting; then highlight the text and choose the <> "Code" option in the editing menu.

We don't have one for all of those options, but I have enabled a filament sensor, SKR Mini, and Linear Advance enabled... We will look at your configuration if you post it, or put a link to it.

Sweet - Although it is 2487 lines of code in just the configuration.h .... Let me see if I can upload them somewhere. I will post back when I get them up!! Thanx!

Ok - <a title="Dropbox Files" href=" removed link " target="true"> removed link  - see if that works. Should have the config and the advanced and a zip file with both in. Hope I did it right.

This is the latest one I did with everything (supposedly) enabled. I have not tried it on the printer yet, busy at the moment, but I did compile it and it says it is fine.

Maybe this 2,834,564,765,876 try is the one that will work who knows lol

Your link didn't work, try again. It doesn't matter how long as the code tags make it scrollable inside the post. Also; I recommend to use pastebin or something instead of dropbox for a configuration file but that's fine.

I will have a look as soon as you rectify the link.

* Marlin allows you to add a custom boot image for Graphical LCDs.
* With this option Marlin will first show your custom screen followed
* by the standard Marlin logo with version number and web URL.
* We encourage you to take advantage of this new feature and we also
* respectfully request that you retain the unmodified Marlin boot screen.

// Show the Marlin bootscreen on startup. ** ENABLE FOR PRODUCTION **

// Show the bitmap in Marlin/_Bootscreen.h on startup.

// Show the bitmap in Marlin/_Statusscreen.h on the status screen.

// @section machine

* Select the serial port on the board to use for communication with the host.
* This allows the connection of wireless adapters (for instance) to non-default port pins.
* Serial port -1 is the USB emulated serial port, if available.
* Note: The first serial port (-1 or 0) will always be used by the Arduino bootloader.
* :[-1, 0, 1, 2, 3, 4, 5, 6, 7]

//====================== PID > Bed Temperature Control ======================

* PID Bed Heating
* If this option is enabled set PID constants below.
* If this option is disabled, bang-bang will be used and BED_LIMIT_SWITCHING will enable hysteresis.
* The PID frequency will be the same as the extruder PWM.
* If PID_dT is the default, and correct for the hardware/configuration, that means 7.689Hz,
* which is fine for driving a square wave into a resistive load and does not significantly
* impact FET heating. This also works fine on a Fotek SSR-10DA Solid State Relay into a 250W
* heater. If your configuration is significantly different than this and you don't understand
* the issues involved, don't use bed PID until someone else verifies that your hardware works.


* Max Bed Power
* Applies to all forms of bed control (PID, bang-bang, and bang-bang with hysteresis).
* When set to any value below 255, enables a form of PWM to the bed that acts like a divider
* so don't use it unless you are OK with PWM on your bed. (See the comment on enabling PIDTEMPBED)

// @section extruder

* Prevent extrusion if the temperature is below EXTRUDE_MINTEMP.
* Add M302 to set the minimum extrusion temperature and/or turn
* cold extrusion prevention on and off.

* Prevent a single extrusion longer than EXTRUDE_MAXLENGTH.
* Note: For Bowden Extruders make this large enough to allow load/unload.

//======================== Thermal Runaway Protection =======================

* Thermal Protection provides additional protection to your printer from damage
* and fire. Marlin always includes safe min and max temperature ranges which
* protect against a broken or disconnected thermistor wire.
* The issue: If a thermistor falls out, it will report the much lower
* temperature of the air in the room, and the the firmware will keep
* the heater on.
* If you get "Thermal Runaway" or "Heating failed" errors the
* details can be tuned in Configuration_adv.h

* Nozzle-to-Probe offsets { X, Y, Z }
* - Use a caliper or ruler to measure the distance from the tip of

* - For the Z offset use your best known value and adjust at runtime.
* - Probe Offsets can be tuned at runtime with 'M851', LCD menus, babystepping, etc.

* Clean Nozzle Feature -- EXPERIMENTAL
* Adds the G12 command to perform a nozzle cleaning process.
* Parameters:
* P Pattern
* S Strokes / Repetitions
* T Triangles (P1 only)
* Patterns:
* P0 Straight line (default). This process requires a sponge type material
* at a fixed bed location. "S" specifies strokes (i.e. back-forth motions)
* between the start / end points.
* P1 Zig-zag pattern between (X0, Y0) and (X1, Y1), "T" specifies the
* number of zig-zag triangles to do. "S" defines the number of strokes.
* Zig-zags are done in whichever is the narrower dimension.
* For example, "G12 P1 S1 T3" will execute:
* --
* | (X0, Y1) | /\ /\ /\ | (X1, Y1)
* | | / \ / \ / \ |
* A | | / \ / \ / \ |

* -- +--------------------------------+
* |________|_________|_________|
* T1 T2 T3
* P2 Circular pattern with middle at NOZZLE_CLEAN_CIRCLE_MIDDLE.
* "R" specifies the radius. "S" specifies the stroke count.
* Before starting, the nozzle moves to NOZZLE_CLEAN_START_POINT.
* Caveats: The ending Z should be the same as starting Z.
* Attention: EXPERIMENTAL. G-code arguments may change.

// Increase the FAN PWM frequency. Removes the PWM noise but increases heating in the FET/Arduino
//#define FAST_PWM_FAN

// Use software PWM to drive the fan, as for the heaters. This uses a very low frequency
// which is not as annoying as with the hardware PWM. On the other hand, if this frequency
// is too low, you should also increment SOFT_PWM_SCALE.
//#define FAN_SOFT_PWM

// Incrementing this by 1 will double the software PWM frequency,
// affecting heaters, and the fan if FAN_SOFT_PWM is enabled.
// However, control resolution will be halved for each increment;
// at zero value, there are 128 effective control positions.
// :[0,1,2,3,4,5,6,7]
#define SOFT_PWM_SCALE 0

// If SOFT_PWM_SCALE is set to a value higher than 0, dithering can
// be used to mitigate the associated resolution loss. If enabled,
// some of the PWM cycles are stretched so on average the desired
// duty cycle is attained.

// Temperature status LEDs that display the hotend and bed temperature.
// If all hotends, bed temperature, and target temperature are under 54C
// then the BLUE led is on. Otherwise the RED led is on. (1C hysteresis)
//#define TEMP_STAT_LEDS

// Support for the BariCUDA Paste Extruder

// Support for BlinkM/CyzRgb
//#define BLINKM

// Support for PCA9632 PWM LED driver
//#define PCA9632

// Support for PCA9533 PWM LED driver
//#define PCA9533

* RGB LED / LED Strip Control
* Enable support for an RGB LED connected to 5V digital pins, or
* an RGB Strip connected to MOSFETs controlled by digital pins.
* Adds the M150 command to set the LED (or LED strip) color.
* If pins are PWM capable (e.g., 4, 5, 6, 11) then a range of
* luminance values can be set from 0 to 255.
* For NeoPixel LED an overall brightness parameter is also available.
* LED Strips require a MOSFET Chip between PWM lines and LEDs,
* as the Arduino cannot handle the current the LEDs will require.
* Failure to follow this precaution can destroy your Arduino!
* NOTE: A separate 5V power supply is required! The NeoPixel LED needs
* more current than the Arduino 5V linear regulator can produce.
* LED Type. Enable only one of the following two options.
//#define RGB_LED
//#define RGBW_LED

//#define RGB_LED_R_PIN 34
//#define RGB_LED_G_PIN 43
//#define RGB_LED_B_PIN 35
//#define RGB_LED_W_PIN -1

// Support for Adafruit NeoPixel LED driver
//#define NEOPIXEL_LED
#define NEOPIXEL_TYPE NEO_GRB // NEO_GRBW / NEO_GRB - four/three channel driver type (defined in Adafruit_NeoPixel.h)
//#define NEOPIXEL_PIN 4 // LED driving pin
//#define NEOPIXEL2_PIN 5
#define NEOPIXEL_PIXELS 10 // Number of LEDs in the strip. (Longest strip when NEOPIXEL2_SEPARATE is disabled.)
#define NEOPIXEL_IS_SEQUENTIAL // Sequential display for temperature change - LED by LED. Disable to change all LEDs at once.
#define NEOPIXEL_BRIGHTNESS 127 // Initial brightness (0-255)
//#define NEOPIXEL_STARTUP_TEST // Cycle through colors at startup

// Support for second Adafruit NeoPixel LED driver controlled with M150 S1 ...
#define NEOPIXEL2_PIXELS 15 // Number of LEDs in the second strip
#define NEOPIXEL2_BRIGHTNESS 127 // Initial brightness (0-255)
#define NEOPIXEL2_STARTUP_TEST // Cycle through colors at startup
//#define NEOPIXEL2_INSERIES // Default behavior is NeoPixel 2 in parallel

// Use a single NeoPixel LED for static (background) lighting
//#define NEOPIXEL_BKGD_LED_INDEX 0 // Index of the LED to use
//#define NEOPIXEL_BKGD_COLOR { 255, 255, 255, 0 } // R, G, B, W

* Printer Event LEDs
* During printing, the LEDs will reflect the printer status:
* - Gradually change from blue to violet as the heated bed gets to target temp
* - Gradually change from violet to red as the hotend gets to temperature
* - Change to white to illuminate work surface
* - Change to green once print has finished
* - Turn off after the print has finished and the user has pushed a button

* Number of servos
* For some servo-related options NUM_SERVOS will be set automatically.
* Set this manually if there are extra servos needing manual control.
* Set to 0 to turn off servo support.
//#define NUM_SERVOS 3 // Servo index starts with 0 for M280 command

// (ms) Delay before the next move will start, to give the servo time to reach its target angle.
// 300ms is a good value but you can try less delay.
// If the servo can't reach the requested position, increase it.
#define SERVO_DELAY { 300 }

// Only power servos during movement, otherwise leave off to prevent jitter

// Edit servo angles with M281 and save to EEPROM with M500

 * is reported.  This allows us to ignore intermittent error conditions while
 * still detecting an actual failure, which should result in a continuous
 * stream of errors from the sensor.
 * Set this value to 0 to fail on the first error to occur.

 * Thermal Protection provides additional protection to your printer from damage
 * and fire. Marlin always includes safe min and max temperature ranges which
 * protect against a broken or disconnected thermistor wire.
 * The issue: If a thermistor falls out, it will report the much lower
 * temperature of the air in the room, and the the firmware will keep
 * the heater on.
 * The solution: Once the temperature reaches the target, start observing.
 * If the temperature stays too far below the target (hysteresis) for too
 * long (period), the firmware will halt the machine as a safety precaution.

    #define DEFAULT_Kc (100) // heating power = Kc * e_speed
    #define LPQ_MAX_LEN 50

   * Add an experimental additional term to the heater power, proportional to the fan speed.
   * A well-chosen Kf value should add just enough power to compensate for power-loss from the cooling fan.
   * You can either just add a constant compensation with the DEFAULT_Kf value
   * or follow the instruction below to get speed-dependent compensation.
   * Constant compensation (use only with fanspeeds of 0% and 100%)
   * ---------------------------------------------------------------------
   * A good starting point for the Kf-value comes from the calculation:
   *   kf = (power_fan * eff_fan) / power_heater * 255
   * where eff_fan is between 0.0 and 1.0, based on fan-efficiency and airflow to the nozzle / heater.
   * Example:
   *   Heater: 40W, Fan: 0.1A * 24V = 2.4W, eff_fan = 0.8
   *   Kf = (2.4W * 0.8) / 40W * 255 = 12.24
   * Fan-speed dependent compensation
   * --------------------------------
   * 1. To find a good Kf value, set the hotend temperature, wait for it to settle, and enable the fan (100%).
   *    If you see the temperature drop repeat the test, increasing the Kf value slowly, until the temperature
   *    drop goes away. If the temperature overshoots after enabling the fan, the Kf value is too big.
   * 2. Note the Kf-value for fan-speed at 100%
   * 3. Determine a good value for PID_FAN_SCALING_MIN_SPEED, which is around the speed, where the fan starts moving.
   * 4. Repeat step 1. and 2. for this fan speed.
   * 5. Enable PID_FAN_SCALING_ALTERNATIVE_DEFINITION and enter the two identified Kf-values in
  //#define PID_FAN_SCALING
      // The alternative definition is used for an easier configuration.
      // Just figure out Kf at fullspeed (255) and PID_FAN_SCALING_MIN_SPEED.
      // DEFAULT_Kf and PID_FAN_SCALING_LIN_FACTOR are calculated accordingly.

      #define PID_FAN_SCALING_MIN_SPEED 10.0            // Minimum fan speed at which to enable PID_FAN_SCALING


      #define PID_FAN_SCALING_LIN_FACTOR (0)             // Power loss due to cooling = Kf * (fan_speed)

      #define PID_FAN_SCALING_MIN_SPEED 10               // Minimum fan speed at which to enable PID_FAN_SCALING

 * Automatic Temperature Mode
 * Dynamically adjust the hotend target temperature based on planned E moves.
 * (Contrast with PID_EXTRUSION_SCALING, which tracks E movement and adjusts PID
 *  behavior using an additional kC value.)
 * Autotemp is calculated by (mintemp + factor * mm_per_sec), capped to maxtemp.
 * Enable Autotemp Mode with M104/M109 F<factor> S<mintemp> B<maxtemp>.

 * High Temperature Thermistor Support
 * Thermistors able to support high temperature tend to have a hard time getting
 * good readings at room and lower temperatures. This means HEATER_X_RAW_LO_TEMP
 * will probably be caught when the heating element first turns on during the
 * preheating process, which will trigger a min_temp_error as a safety measure
 * and force stop everything.
 * To circumvent this limitation, we allow for a preheat time (during which,
 * min_temp_error won't be triggered) and add a min_temp buffer to handle
 * aberrant readings.
 * If you want to enable this feature for your hotend thermistor(s)
 * uncomment and set values > 0 in the constants below

// The number of consecutive low temperature errors that can occur
// before a min_temp_error is triggered. (Shouldn't be more than 10.)

// The number of milliseconds a hotend will preheat before starting to check
// the temperature. This value should NOT be set to the time it takes the
// hot end to reach the target temperature, but the time it takes to reach
// the minimum temperature your thermistor can read. The lower the better/safer.
// This shouldn't need to be more than 30 seconds (30000)

 * Define the min/max speeds for PWM fans (as set with M106).
 * With these options the M106 0-255 value range is scaled to a subset
 * to ensure that the fan has enough power to spin, or to run lower
 * current fans with higher current. (e.g., 5V/12V fans with 12V/24V)
 * Value 0 always turns off the fan.

//#define FAN_MIN_PWM 50

 * FAST PWM FAN Settings
 * Use to change the FAST FAN PWM frequency (if enabled in Configuration.h)
 * Combinations of PWM Modes, prescale values and TOP resolutions are used internally to produce a
 * frequency as close as possible to the desired frequency.
 * FAST_PWM_FAN_FREQUENCY [undefined by default]
 *   Set this to your desired frequency.
 *   If left undefined this defaults to F = F_CPU/(2*255*1)
 *   i.e., F = 31.4kHz on 16MHz microcontrollers or F = 39.2kHz on 20MHz microcontrollers.
 *   These defaults are the same as with the old FAST_PWM_FAN implementation - no migration is required
 *   NOTE: Setting very low frequencies (< 10 Hz) may result in unexpected timer behavior.
 * USE_OCR2A_AS_TOP [undefined by default]
 *   Boards that use TIMER2 for PWM have limitations resulting in only a few possible frequencies on TIMER2:
 *   16MHz MCUs: [62.5KHz, 31.4KHz (default), 7.8KHz, 3.92KHz, 1.95KHz, 977Hz, 488Hz, 244Hz, 60Hz, 122Hz, 30Hz]
 *   20MHz MCUs: [78.1KHz, 39.2KHz (default), 9.77KHz, 4.9KHz, 2.44KHz, 1.22KHz, 610Hz, 305Hz, 153Hz, 76Hz, 38Hz]
 *   A greater range can be achieved by enabling USE_OCR2A_AS_TOP. But note that this option blocks the use of
 *   PWM on pin OC2A. Only use this option if you don't need PWM on 0C2A. (Check your schematic.)
 *   USE_OCR2A_AS_TOP sacrifices duty cycle control resolution to achieve this broader range of frequencies.

 * Dual Steppers / Dual Endstops
 * This section will allow you to use extra E drivers to drive a second motor for X, Y, or Z axes.
 * For example, set X_DUAL_STEPPER_DRIVERS setting to use a second motor. If the motors need to
 * spin in opposite directions set INVERT_X2_VS_X_DIR. If the second motor needs its own endstop
 * set X_DUAL_ENDSTOPS. This can adjust for "racking." Use X2_USE_ENDSTOP to set the endstop plug
 * that should be used for the second endstop. Extra endstops will appear in the output of 'M119'.
 * Use X_DUAL_ENDSTOP_ADJUSTMENT to adjust for mechanical imperfection. After homing both motors
 * this offset is applied to the X2 motor. To find the offset home the X axis, and measure the error
 * in X2. Dual endstop offsets can be set at runtime with 'M666 X<offset> Y<offset> Z<offset>'.

 * Dual X Carriage
 * This setup has two X carriages that can move independently, each with its own hotend.
 * The carriages can be used to print an object with two colors or materials, or in
 * "duplication mode" it can print two identical or X-mirrored objects simultaneously.
 * The inactive carriage is parked automatically to prevent oozing.
 * X1 is the left carriage, X2 the right. They park and home at opposite ends of the X axis.
 * By default the X2 stepper is assigned to the first unused E plug on the board.
 * The following Dual X Carriage modes can be selected with M605 S<mode>:
 *   0 : (FULL_CONTROL) The slicer has full control over both X-carriages and can achieve optimal travel
 *       results as long as it supports dual X-carriages. (M605 S0)
 *   1 : (AUTO_PARK) The firmware automatically parks and unparks the X-carriages on tool-change so
 *       that additional slicer support is not required. (M605 S1)
 *   2 : (DUPLICATION) The firmware moves the second X-carriage and extruder in synchronization with
 *       the first X-carriage and extruder, to print 2 copies of the same object at the same time.
 *       Set the constant X-offset and temperature differential with M605 S2 X[offs] R[deg] and
 *       follow with M605 S2 to initiate duplicated movement.
 *   3 : (MIRRORED) Formbot/Vivedino-inspired mirrored mode in which the second extruder duplicates
 *       the movement of the first except the second extruder is reversed in the X axis.
 *       Set the initial X offset and temperature differential with M605 S2 X[offs] R[deg] and
 *       follow with M605 S3 to initiate mirrored movement.
  #define X1_MIN_POS X_MIN_POS   // Set to X_MIN_POS

 * The photo can be triggered by a digital pin or a physical movement.
//#define PHOTO_GCODE
  // A position to move to (and raise Z) before taking the photo
  //#define PHOTO_POSITION { X_MAX_POS - 5, Y_MAX_POS, 0 }  // { xpos, ypos, zraise } (M240 X Y Z)

  // Duration to hold the switch or keep CHDK_PIN high
  //#define PHOTO_SWITCH_MS   50 // (ms) (M240 D)

   * PHOTO_PULSES_US may need adjustment depending on board and camera model.
   * Pin must be running at 48.4kHz.
   * Be sure to use a PHOTOGRAPH_PIN which can rise and fall quick enough.
   * (e.g., MKS SBase temp sensor pin was too slow, so used P1.23 on J8.)

    #define PHOTO_PULSE_DELAY_US 13 // (µs) Approximate duration of each HIGH and LOW pulse in the oscillation

 * Spindle & Laser control
 * Add the M3, M4, and M5 commands to turn the spindle/laser on and off, and
 * to set spindle speed, spindle direction, and laser power.
 * SuperPid is a router/spindle speed controller used in the CNC milling community.
 * Marlin can be used to turn the spindle on and off. It can also be used to set
 * the spindle speed from 5,000 to 30,000 RPM.
 * You'll need to select a pin for the ON/OFF function and optionally choose a 0-5V
 * hardware PWM pin for the speed control and a pin for the rotation direction.
 * See for more config details.
  #define SPINDLE_LASER_ACTIVE_STATE    LOW    // Set to "HIGH" if the on/off function is active HIGH
  #define SPINDLE_LASER_PWM             true   // Set to "true" if your controller supports setting the speed/power
  #define SPINDLE_LASER_PWM_INVERT      false  // Set to "true" if the speed/power goes up when you want it to go slower

  #define SPINDLE_LASER_FREQUENCY       2500   // (Hz) Spindle/laser frequency (only on supported HALs: AVR and LPC)

   * Speed / Power can be set ('M3 S') and displayed in terms of:
   *  - PWM255  (S0 - S255)
   *  - PERCENT (S0 - S100)
   *  - RPM     (S0 - S50000)  Best for use with a spindle

   * Relative Cutter Power
   * Normally, 'M3 O<power>' sets
   * OCR power is relative to the range SPEED_POWER_MIN...SPEED_POWER_MAX.
   * so input powers of 0...255 correspond to SPEED_POWER_MIN...SPEED_POWER_MAX
   * instead of normal range (0 to SPEED_POWER_MAX).
   * Best used with (e.g.) SuperPID router controller: S0 = 5,000 RPM and S255 = 30,000 RPM
  //#define CUTTER_POWER_RELATIVE              // Set speed proportional to [SPEED_POWER_MIN...SPEED_POWER_MAX]

    //#define SPINDLE_CHANGE_DIR               // Enable if your spindle controller can change spindle direction
    #define SPINDLE_CHANGE_DIR_STOP            // Enable if the spindle should stop before changing spin direction
    #define SPINDLE_INVERT_DIR          false  // Set to "true" if the spin direction is reversed

    #define SPINDLE_LASER_POWERUP_DELAY   5000 // (ms) Delay to allow the spindle/laser to come up to speed/power
    #define SPINDLE_LASER_POWERDOWN_DELAY 5000 // (ms) Delay to allow the spindle to stop

     * M3/M4 Power Equation
     * Each tool uses different value ranges for speed / power control.
     * These parameters are used to convert between tool power units and PWM.
     * Speed/Power = (PWMDC / 255 * 100 - SPEED_POWER_INTERCEPT) / SPEED_POWER_SLOPE
    #define SPEED_POWER_INTERCEPT         0    // (%) 0-100 i.e., Minimum power percentage
    #define SPEED_POWER_MIN            5000    // (RPM)
    #define SPEED_POWER_MAX           30000    // (RPM) SuperPID router controller 0 - 30,000 RPM
    #define SPEED_POWER_STARTUP       25000    // (RPM) M3/M4 speed/power default (with no arguments)


    #define SPEED_POWER_INTERCEPT         0    // (%) 0-100 i.e., Minimum power percentage
    #define SPEED_POWER_MIN               0    // (%) 0-100
    #define SPEED_POWER_MAX             100    // (%) 0-100
    #define SPEED_POWER_STARTUP          80    // (%) M3/M4 speed/power default (with no arguments)

     * Enable inline laser power to be handled in the planner / stepper routines.
     * Inline power is specified by the I (inline) flag in an M3 command (e.g., M3 S20 I)
     * or by the 'S' parameter in G0/G1/G2/G3 moves (see LASER_MOVE_POWER).
     * This allows the laser to keep in perfect sync with the planner and removes
     * the powerup/down delay since lasers require negligible time.
    //#define LASER_POWER_INLINE

       * Scale the laser's power in proportion to the movement rate.
       * - Sets the entry power proportional to the entry speed over the nominal speed.
       * - Ramps the power up every N steps to approximate the speed trapezoid.
       * - Due to the limited power resolution this is only approximate.

       * Continuously calculate the current power (nominal_power * current_rate / nominal_rate).
       * Required for accurate power with non-trapezoidal acceleration (e.g., S_CURVE_ACCELERATION).
       * This is a costly calculation so this option is discouraged on 8-bit AVR boards.
       * LASER_POWER_INLINE_TRAPEZOID_CONT_PER defines how many step cycles there are between power updates. If your
       * board isn't able to generate steps fast enough (and you are using LASER_POWER_INLINE_TRAPEZOID_CONT), increase this.
       * Note that when this is zero it means it occurs every cycle; 1 means a delay wait one cycle then run, etc.

       * Stepper iterations between power updates. Increase this value if the board
       * can't keep up with the processing demands of LASER_POWER_INLINE_TRAPEZOID_CONT.
       * Disable (or set to 0) to recalculate power on every stepper iteration.

       * Include laser power in G0/G1/G2/G3/G5 commands with the 'S' parameter
      //#define LASER_MOVE_POWER

        // Turn off the laser on G0 moves with no power parameter.
        // If a power parameter is provided, use that instead.
        //#define LASER_MOVE_G0_OFF

        // Turn off the laser on G28 homing.
        //#define LASER_MOVE_G28_OFF

       * Inline flag inverted
       * WARNING: M5 will NOT turn off the laser unless another move
       *          is done (so G-code files must end with 'M5 I').

       * Continuously apply inline power. ('M3 S3' == 'G1 S3' == 'M3 S3 I')
       * The laser might do some weird things, so only enable this
       * feature if you understand the implications.


      #define SPINDLE_LASER_POWERUP_DELAY     50 // (ms) Delay to allow the spindle/laser to come up to speed/power
      #define SPINDLE_LASER_POWERDOWN_DELAY   50 // (ms) Delay to allow the spindle to stop


 * Coolant Control
 * Add the M7, M8, and M9 commands to turn mist or flood coolant on and off.
 * Note: COOLANT_MIST_PIN and/or COOLANT_FLOOD_PIN must also be defined.
  #define COOLANT_MIST                // Enable if mist coolant is present
  #define COOLANT_FLOOD               // Enable if flood coolant is present
  #define COOLANT_MIST_INVERT  false  // Set "true" if the on/off function is reversed
  #define COOLANT_FLOOD_INVERT false  // Set "true" if the on/off function is reversed

 * Filament Width Sensor
 * Measures the filament width in real-time and adjusts
 * flow rate to compensate for any irregularities.
 * Also allows the measured filament diameter to set the
 * extrusion rate, so the slicer only has to specify the
 * volume.
 * Only a single extruder is supported at this time.
 *  34 RAMPS_14    : Analog input 5 on the AUX2 connector
 *  81 PRINTRBOARD : Analog input 2 on the Exp1 connector (version B,C,D,E)
 * 301 RAMBO       : Analog input 3
 * Note: May require analog pins to be defined for other boards.

  #define FILAMENT_SENSOR_EXTRUDER_NUM 0    // Index of the extruder that has the filament sensor. :[0,1,2,3,4]
  #define MEASUREMENT_DELAY_CM        14    // (cm) The distance from the filament sensor to the melting chamber

  #define FILWIDTH_ERROR_MARGIN        1.0  // (mm) If a measurement differs too much from nominal width ignore it
  #define MAX_MEASUREMENT_DELAY       20    // (bytes) Buffer size for stored measurements (1 byte per cm). Must be larger than MEASUREMENT_DELAY_CM.

  #define DEFAULT_MEASURED_FILAMENT_DIA DEFAULT_NOMINAL_FILAMENT_DIA // Set measured to nominal initially

  // Display filament width on the LCD status line. Status messages will expire after 5 seconds.

 * Power Monitor
 * Monitor voltage (V) and/or current (A), and -when possible- power (W)
 * Read and configure with M430
 * The current sensor feeds DC voltage (relative to the measured current) to an analog pin
 * The voltage sensor feeds DC voltage (relative to the measured voltage) to an analog pin
//#define POWER_MONITOR_CURRENT   // Monitor the system current
//#define POWER_MONITOR_VOLTAGE   // Monitor the system voltage
  #define POWER_MONITOR_VOLTS_PER_AMP   0.05000   // Input voltage to the MCU analog pin per amp  - DO NOT apply more than ADC_VREF!
  #define POWER_MONITOR_CURRENT_OFFSET -1         // Offset value for current sensors with linear function output
  #define POWER_MONITOR_VOLTS_PER_VOLT  0.11786   // Input voltage to the MCU analog pin per volt - DO NOT apply more than ADC_VREF!
  #define POWER_MONITOR_FIXED_VOLTAGE   13.6      // Voltage for a current sensor with no voltage sensor (for power display)

 * CNC Coordinate Systems
 * Enables G53 and G54-G59.3 commands to select coordinate systems
 * and G92.1 to reset the workspace to native machine space.

 * Auto-report temperatures with M155 S<seconds>

 * Include capabilities in M115 output
  //#define M115_GEOMETRY_REPORT

 * Expected Printer Check
 * Add the M16 G-code to compare a string to the MACHINE_NAME.
 * M16 with a non-matching string causes the printer to halt.

 * Disable all Volumetric extrusion options

   * Volumetric extrusion default state
   * Activate to make volumetric extrusion the default method,
   * with DEFAULT_NOMINAL_FILAMENT_DIA as the default diameter.
   * M200 D0 to disable, M200 Dn to set a new diameter (and enable volumetric).
   * M200 S0/S1 to disable/enable volumetric extrusion.

     * Default volumetric extrusion limit in cubic mm per second (mm^3/sec).
     * This factory setting applies to all extruders.
     * Use 'M200 [T<extruder>] L<limit>' to override and 'M502' to reset.
     * A non-zero value activates Volume-based Extrusion Limiting.
    #define DEFAULT_VOLUMETRIC_EXTRUDER_LIMIT 0.00      // (mm^3/sec)

 * Enable this option for a leaner build of Marlin that removes all
 * workspace offsets, simplifying coordinate transformations, leveling, etc.
 *  - M206 and M428 are disabled.
 *  - G92 will revert to its behavior from Marlin 1.0.

// Extra options for the M114 "Current Position" report
//#define M114_DETAIL         // Use 'M114` for details to check planner calculations
//#define M114_REALTIME       // Real current position based on forward kinematics
//#define M114_LEGACY         // M114 used to synchronize on every call. Enable if needed.

//#define REPORT_FAN_CHANGE   // Report the new fan speed when changed by M106 (and others)

 * Set the number of proportional font spaces required to fill up a typical character space.
 * This can help to better align the output of commands like `G29 O` Mesh Output.
 * For clients that use a fixed-width font (like OctoPrint), leave this set to 1.0.
 * Otherwise, adjust according to your client and font.

 * Spend 28 bytes of SRAM to optimize the GCode parser

 * CNC G-code options
 * Support CNC-style G-code dialects used by laser cutters, drawing machine cams, etc.
 * Note that G0 feedrates should be used with care for 3D printing (if used at all).
 * High feedrates may cause ringing and harm print quality.
//#define PAREN_COMMENTS      // Support for parentheses-delimited comments
//#define GCODE_MOTION_MODES  // Remember the motion mode (G0 G1 G2 G3 G5 G38.X) and apply for X Y Z E F, etc.

 * Startup commands
 * Execute certain G-code commands immediately after power-on.
//#define STARTUP_COMMANDS "M17 Z"

 * G-code Macros
 * Add G-codes M810-M819 to define and run G-code macros.
 * Macros are not saved to EEPROM.
//#define GCODE_MACROS
  #define GCODE_MACROS_SLOTS       5  // Up to 10 may be used

 * Host Action Commands
 * Define host streamer action commands in compliance with the standard.
 * See
 * Common commands ........ poweroff, pause, paused, resume, resumed, cancel
 * G29_RETRY_AND_RECOVER .. probe_rewipe, probe_failed
 * Some features add reason codes to extend these commands.

 * NanoDLP Sync support
 * Add support for Synchronized Z moves when using with NanoDLP. G0/G1 axis moves will output "Z_move_comp"
 * string to enable synchronization with DLP projector exposure. This change will allow to use

So I finally got it to print with the above configuration but it starts a couple MM above the bed and the z offset wont adjust it lol - I am about ready to go back to the old creality silent board. I always say people do too much to their printers and here I went and tried to go 32-bit *sigh*

More updates - this thread is going to be really long LOL

I found out the z offset LIVE is not working. I can change the z offset but have to do it, save it and then reprint my test file - This is in MARLIN mode on the tft35.

Main reason I am using MARLIN mode on the tft35 is because I get a bunch of errors in touch mode and I still have not been able to get anything to print in touch mode! It is so weird as I can print the file perfect in MARLIN mode but it just sits there extruding filament in touch screen mode.

Filament sensor is hooked up but I have turned it off in the touch menu settings for now. I wanted to try and get it printing properly first so now I am going to see if I can get that beast working.

Still really curious about the config files above and whether they are actually correct or not.

Another minute, another post lol.

Ok so I think I figured this out. Still need to run some tests but it seems the filament runout sensor will not work in BOTH marlin and touch mode. Hook to the motherboard and it works in marlin, hook to the tft35 and it works in touch mode - HOW STUPID IS THIS? I hope BigTreeTech reads this as this is the most insane thing I have heard since you hook everything to the motherboard (bltouch anyone) and it can be controlled in touch mode so why not THEIR OWN device? *sigh*

I am printing right now in touch mode after figuring this little tidbit out and turning off the filament sensor in touch mode. Printing a bracket for the filament runout sensor ROFLMAO I think I have gone insane.

Okay, I am a little confused now. I think you have to hook the filament runout sensor to the pins that BTT have defined in their pin definitions.

Also, I have heard a lot of people having issues with the touch and marlin mode both on one screen. You have to hook both sets of wires up to the motherboard, and enable it in the config. I have also heard about issues with the touch mode and marlin mode with filament sensors. See the reply on this subreddit for other person having that issue, maybe reply to them?


Most of your changes look good, you may need a few more. Also make sure you are wired up to PC15 + GND on the board. Below are the changes required for the Filament Runout sensor:

Filament Runout Sensor/Detection and Filament Change

E0-STOP (PC15)

    • (Length from the extruder gear to the nozzle + 10)
    • (Change it to your retraction speed)
    • (Change it to your retraction length)
    • (Length from the extruder gear to the nozzle OR set it to 0 for manual filament extraction)
    • (This needs to be less than or equal to EXTRUDE_MAXLENGTH)
    • (Length from the extruder gear to the nozzle OR set it to 0 for manual filament insertion)
    • (This needs to be less than or equal to EXTRUDE_MAXLENGTH)
    • (10 might be too much/annoying, if so, lower it to your liking)
    • (Adds M701/M702 Load/Unload G-code, and Load/Unload in the LCD Prepare menu.)

Yes I have it wired to the E0-STOP on the mainboard. Maybe i was confusing myself as I thought some were saying the sensor could be hooked direct to the tft35 to use touch mode OR hooked to the motherboard to use in marlin mode. My brain is going buggy from all this 🙂

One other problem I found is it has the Z steps at 800 while mine is the original Ender 5 so I had to change to 400mm and now I have to redo the z offset and it is a pain in the butt because the live changing doesnt work 🙁

I am going to go through my config file and see about the ones you listed. I still have not even tried the runout sensor, I just have it attached but calibrating comes first.
