M569 P3 S0

Thank you so much. Do I have to reverse it every time I turn the printer on or was it just an initial setting mistake I didn't pay attention to?

Gixxerfast

@re_tour No, just change it once in config.g and it wasn't a mistake. Really hard to know how the wires are supposed to be, just as long as the pairs are correct it's good. Many has to adjust that AFAIK.

re_tour

@gixxerfast Thank you very much!

re_tour

@gixxerfast So I didn't input that change into the config.g yet, but wrote it into the console. Printed 2 things, the strange thing is that at the end of each print the mechanism pulls the filament all the way out. Why could that be?

Gixxerfast

@re_tour You must have something wonky in your slicer. Check if there some custom end print gcode in Cura (it was Cura you were using, right?)

re_tour

@gixxerfast Yes sir, let me check.

@gixxerfast This is the last few lines of the first gcode:

;TIME_ELAPSED:2311.874865
G1 F2700 E788.98313
M140 S0
M107
G91 ;Relative positioning
G1 E-2 F2700 ;Retract a bit
G1 E-2 Z0.2 F2400 ;Retract and raise Z

and the end of the second gcode:

I really don't have a clue. I'm just guessing but...

Try to find where these are inserted

And comment them out /remove them.

See if it makes any difference.

@gixxerfast You were right, G1 E-2 F2700 pulls the filament nearly all the way out. Thank you (once again)

Gixxerfast

@re_tour That's great!
Happy printing!

I think you might have to revisit the offset configuration. The mesh looked a bit shifted. But that's for another day

and as long as it prints and you get the first layer right, it works
