just finished building an eggbot kit and wanted to give it a try on the old laptop (still running XP) here in my hobby room.. looked like everything installed fine, but it seems something’s not quite right. if i enable the motors the pen-servo starts jumping quite erratically.
i shot a video, but it’s taking quite a while uploading from here, will post the link to it when i arrive home. but maybe someone knows about this kind of issues..
The “enable motors” command doesn’t actually do anything to the servo, it just turns on power to the steppers. That suggests that it could be a power supply problem or (yes) some other problem on the EBB. Are you using the original power supply?
