both stepper motors are working fine, but the pen servo only goes to the almost the maximum upper position and then does not move. When power is turned off and then on again, it briefly goes to the absolut maximum, and then returns to almost maximum. No control options from Inkscape makes it move.
I asked the EBB for its version info, and it replied:
EBBv13_and_above EB Firmware Version 2.0.1
I'm using a mac with os x 10.8.2.
The eggbot was built yesterday. Help appreciated.
