Hello,

New to 3d printing. My printer was working great, printing tons of things with my son. I upgraded the Motherboard to the SKR Mini E3 V2 and it worked even better..

Then I got a Genuine BLtouch V3.1 and I cannot print. Ive download tons of Marlin files and even used this https://www.reddit.com/r/ender3/comments/h8y1ia/marlin_20x_guide_skr_mini_e3_v20_ender_3/

a couple of times.

1) I cannot get the VSCode to upload

2) when it was printing it was pringing off the front of the bed

3) when I use pronterface "TMC connection Error"

4) if I autohome the extruder shoots to the right and makes a horrible noise.

 

I recently got rid of the springs and use silicone bushings

https://www.thingiverse.com/thing:3148733

is the Mount Im using for the BLtouch.

if anyone could help I would greatly appreciate it!!

 

Let me know and I can send you the VSCode I'm using, well not working..

Hello!

So, was the board working before you attached the BLTouch and now it isn't? Have you tried to disconnect the BLTouch and the machine work again?

 

Or did you upload a firmware partially and cause it to become corrupted? Pronterface should still connect to the mainboard even if there is a TMC connection error.

Have you tried the version of Marlin for BLtouch from our website?

yes it was working great with the new board. The trouble started when I got the new BLtouch 3.1

I have not disconnected the BLtouch but that is a good idea, I just got silicone bushing to replace the springs with.

 

Pronterface just says printer is online. it doesnt give more info like I have been reading it should.

 

I haven't tried the firmware from  your website, but I will now.

Thank you for helping

You would need to try the one for the Ender 3, and enable the BLTouch stuff. I would try to make sure the printer works on basic firmware before enabling anything on BLTouch though.

 

Pronterface should connect, and be able to move the axis with the GUI.

@print3d

 

if I can move the printer axis with pronterface is the TMC error relevant?

@boddingtonsz

It's relevant still, last time I had that TMC error I burned up my Z axis motor due to the incorrect settings. The relevant settings for Ender 3 and that error are in Advanced Configuration; My firmware that I uploaded on the website has the correct settings in it I believe.

Are you saying your printer is still working via pronterface?

Look in adv_config under tmc_smart and these settings to fix the TMC connection error.

 

  #define  X_SLAVE_ADDRESS 0

  #define  Y_SLAVE_ADDRESS 2

  #define  Z_SLAVE_ADDRESS 1

  #define X2_SLAVE_ADDRESS 0

  #define Y2_SLAVE_ADDRESS 0

  #define Z2_SLAVE_ADDRESS 0

  #define Z3_SLAVE_ADDRESS 0

  #define Z4_SLAVE_ADDRESS 0

  #define E0_SLAVE_ADDRESS 3

  #define E1_SLAVE_ADDRESS 0

  #define E2_SLAVE_ADDRESS 0

  #define E3_SLAVE_ADDRESS 0

  #define E4_SLAVE_ADDRESS 0

  #define E5_SLAVE_ADDRESS 0

  #define E6_SLAVE_ADDRESS 0

  #define E7_SLAVE_ADDRESS 0

And you are still experiencing the TMC connection error on your HMI? Are you sure it's a Ender 3 regular running the SKR Mini E3 v2.0 and NOT the version 1.2 or 1.3?

HMI?

yes I have the SKR Mini E3 V2.0

and lol.. I have another issue

So I think I fixed the BLTouch and size of bed, I used your software. but now it doesn't feed filament.

the knob I printed turns but no filament is coming out.

I went online last night to see whats up and found its most likely the stock Bowden extruder? so I purchased a metal dual bowden extruder and going to put it on tonight. is there anything else it could be?

I cleaned the nozzle, then turned it up to 250 and manually pushed through some filament. I haven't taken off the nozzle though, I may have to do that.

I want to get this guy working through the SD 1st then go to pronterface or Repetier (downloaded haven't messed with yet) or which ever you recommend. I was thinking Repetier because I'm familiar with Cura.

@boddingtonsz

Pronterface or Repetier doesn't matter; I advise you to use the SD card slot if you don't have a Raspberry Pi running octoprint. Glad that software fixed your issues.

Did you make sure you have proper tension on the extruder and the plastic arm isn't broken? If the extruder is spinning but not moving filament you could have a jam. Try to heat it up, and pull the filament out by hand. If you can push it by hand, and the extruder is turning; but no filament is coming out then it must be tension arm on the extruder.

Thanks so much for all your help!

I got the new Extruder and it was missing parts, so I'm going to send it back and order again. Apparently the Stock Extruder has issues.

Ill let you know whats going on when I reinstall it.

Thanks again!
