Dual extruder but only one move

raymond

Hi,hope somebody can help me with this.

I config the repetier firmware 0.92.9 version with the online config tools,dual extruder, when I test my printer,all steppers move pretty well  except the one for  extruder 1, when I move it on LCD controller, with temperature reach minimum,

As showed in this photo,the E on the top is alway 0.00mm,yet the E below moves though, and motor doesn't move a bit.

The other motor for Extruder 0 works perfectly.I don't know what happen.Could somebody tell me what to do?

You might have set steps per mm in eeprom to nan or 0. That would cause such problems. Happens especially if you had 1 extruder config in the past. In that case also check the other eeprom values for extruder 1.
