Just got a WatercolorBot and ran into some issues. The motors seemed to be cogging so I went through all the suggested steps to fix and now it's really not working properly. I also checked the voltage and it seems to be correct.
The servo is twitching slightly up and down any time I plug the power in, whether USB is plugged in or not.
When I try to run a paint job
Running MacBook Pro w/ El Capitan with the 2.0 RoboPaint release. I'm hoping I didn't screw things up beyond repair. Thanks for any help.
