Stepper Extruder problem Hello, I have following problem with my stepper extruder. I want to test the stepper extruder. If I select extrude it does not work but if I select reverse it works. So stepper only works in one direction. I checked the hardware (both H-bridges work with DC motors) Stepper motor works in both directions on stepper control board but not on extruder controller board Any ideas or suggestions what could be wrong? thx https://reprap.org/forum/read.php?151,59490,59490#msg-59490 Thu, 12 Mar 2026 13:25:45 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?151,59490,66698#msg-66698 Re: Stepper Extruder problem https://reprap.org/forum/read.php?151,59490,66698#msg-66698 Please post a picture of how you have it connected.

But I found it.

In my Gen3 electronics the analog ground and digital ground was not connected and that caused the problem.

I have following problem with my stepper extruder.
I want to test the stepper extruder. If I select extrude it does not work but if I select reverse it works.
So stepper only works in one direction. I checked the hardware (both H-bridges work with DC motors)
Stepper motor works in both directions on stepper control board but not on extruder controller board

Any ideas or suggestions what could be wrong?
