Extruder motor not working

[cujul]

Hello,

I use Mach3 with the config I found on the yahoo group.
Motors X,Y,Z are working fine but when I try one of the Gcode found on seemecnc.org (star.nc) or generated by replicatorg (modified version), the motor don't move.
i set up pin 16 and 17 for extruder step and dir.

I think the problem is in the config of mach3,so I will try EMC2.

Any idea?

cujul, are you using an easydriver to run the extruder motor? If so, you might have some old gcode that was before we used that setup. Try using slic3r and generating your own g-code from an stl on thingiverse, and i bet it will work then. Odds are that old gcode file was for a constand speed extruder setup we had origionally. Look at the top of the gcode and you will see a Sxxx M03 and that will tell you it was an old file

Yes, I have the easydriver.

When I run the slic3r gcode with my demo of Mach3, it'sblocked on " G82 E0 ; Reset extruson distance" or any other instructions if I remove some of them.

Could you post a slic3r config?

I would like to test the extruder motor on Mach3 without a gcode, is it possible? (like with X,Y,Z axis on right,left,up,down,pg up and pg down keys)

EDIT: Also, the Z axis don't go on the good direction (when I hit PGUP, it go down), how to set this properly?

Ah, ok. In slicer, make sure you use the G-Code flavour (under printer tab) of mach3/EMC. The hotkeys for A axis are the 10-key plus and minus keys.
