775 pro with a Versaplanetary gearbox bolted to a piece of aluminum stock through the side mount holes on the versaplantary. The motor controller is a PWM Spark Max.
When the motor runs in one direction, it runs fine.
When it runs in the opposite direction, it acts like it’s fighting itself. Another motor in the same index subsystem runs funky as well.
If we unbold the versa planetary from the frame, the problem goes away.
We already swapped to a different, new 775 motor. Issue seemed like it was fixed, but is recurring again.
Could there be an electrical issue that goes through the gearbox into the frame? How does that figure since we swapped out for a new motor?
Any help would be greatly appreciated.
