[FRC] [problem] Motor issues...

When I asked if it was hooked up, to a gearbox (and mechanism), I was wondering if that could also be the source of the problem... what gearbox is it? What's hooked up to it? Perhaps post a picture of your setup.

Have you tried swapping the polarity on the motor wires (AFTER the speed controller!) to see if it follows the mechanical system or if it follows the code? Perhaps also try a similar version of this by swapping the polarity of the code. You could be sending conflicting values in separate lines of code.

I'm with Nathan - this may be a case where you're in a mechanical stall condition due to binding, change in surface properties, over-tightening of bolts on a gearbox, or other such type of nuance that isn't obvious. It will become obvious once the motor catches on fire (I kid!), but until then could you post a picture or describe the mechanism?

Write the output to motor controllers to smart dashboard. Easy way of seeing if it is hardware or software. What I am saying? It is always software.
