how come my extruder motor doesnt move?

Hi,

I installed sprinter firmware, when I was controlling it manually in Printrun, I could set the extruder motor to run, but whenever I pressed the print, the motor just didn't turn?

This happened the same to replicatorg software... I could move all axes, but not the extruder...

Can anyone explain to me why is that??

Cheers,
Adrian

I think it has to be firmware + software communication problem?? I just installed repetier.. and it worked fine! Is there any setting that I've missed out in replicatorg and printrun?
