UM3 Invert extruder direction um3

[frankie_um3 1]

Hi, what is command line by putty sfw for inverting direction of bondtech qr extruder?  I don't know where are the lines showed in bondtech troubleshooting or Configuration.h in my um3 frw !!

Please help me

I think these lines are from a different documentation.

There's a separate installation guide for the UM3:

https://support.bondtech.se/Guide/03.+QR+for+Ultimaker+3/14?lang=en

 

But...

The "QR Ultimaker 3 Kit" comes with its own stepper motors, there should be no need to change the rotation direction?

If you use a different setup... the direction of stepper motors can usually be changed by swapping one pair of the four cables.

Which Bondtech instruction tells you to swap wires on a cable? Can you post a link to your document?

 

The document linked by @tinkergnome mentions that the kit comes with new cables, one for the left and another for the right extruder. Did you get two cables? If yes, then perhaps you swapped the cables.
