Topic: extruder motor runs only is one direction

My extruder motor seems to run only in one direction... reverse.

I can put my hand on the end of the motor shaft and feel it is not pulling filament into the extruder head.

anyone know what I can do about this.

Thanks.

Homer

You can confirm by putting a bit of a marker on the Shaft of the extruder.
If it is confirmed you might verify the connectors...

Another possability is the retraction is causing missed steps from being too fast.  My extruder was not limited on MM/S in the eeprom settings and I was getting missed steps on retraction and prime.
