Hi, my extruder go only backware, I know that I can inverse the extruder in the firmware, but the real probleme is that it can go only one way. I tried two firmware Marlin and Sprinter. I know that the motor can go both way, because I tried that motor on an other axe.

If the problem moved with the stepper driver, then you know that particular stepper driver is defective. You can stop here and replace the stepper driver.

If the issue stayed with the extuder, then the issue is probably with your controller. I would trouble shoot these points:

Make sure that the solder join that connects to the direction pin on the stepper driver doesn't have a bad solder joint. To fix a bad joint: Disconnect the controller, remove the stepper driver for that socket, heat the joint with a soldering iron, add solder if needed, allow to cool, reconnect, and test again.

If that didn't fix the problem, use a meter to check the connection from the direction pin of the stepper back to the signaling pin on micro controller to make sure the path isn't interrupted in some way.

The bad thing is both of these issues can be conditional, like the controller has to be so hot or so cool before the issue presents.

When you go into your host (driver) software and tell it to extrude and then tell it to retract does the motor go one direction on extrude and the opposite direction on retract? (For the purpose of this test, it doesn't matter if it's the wrong way.)]]> appdev007 Reprappers Fri, 21 Jun 2013 23:00:50 -0400 https://reprap.org/forum/read.php?4,220303,220391#msg-220391 https://reprap.org/forum/read.php?4,220303,220391#msg-220391 Spartatux Reprappers Fri, 21 Jun 2013 14:42:03 -0400 https://reprap.org/forum/read.php?4,220303,220354#msg-220354 https://reprap.org/forum/read.php?4,220303,220354#msg-220354
With the power off to the printer and the filament removed from the exturder can you turn the extruder both ways by hand relatively easy?]]> appdev007 Reprappers Fri, 21 Jun 2013 12:05:47 -0400 https://reprap.org/forum/read.php?4,220303,220303#msg-220303 https://reprap.org/forum/read.php?4,220303,220303#msg-220303
