Hello,
I've got a reprap set up with all the hardware working -- steppers, extruder, etc working via firmware. When I try to use the host software, however, it seems like the communication between the Arduino is failing. The host software reports the correct temperature but can't seem to move the steppers. I can query the Ardunio via a serial console -- ie M105 to get temperature -- but I'm not sure what to send to make sure I can move steppers.
Any ideas on what could be going wrong?
Thanks
-Jim
