Hi
I am using the Servocity 720oz-in 105rpm gear motors with a roboclaw 2x15A board, and am finding that one wheel always reports about 40 ticks per rev more than the other, which is affecting a mapping application I built my bot for.
I am getting the numbers from the Motion Control app that lets you run PID tuning / setup etc, and I have carried those things out. I suspect I may have damaged a gear when mounting the motor with a mounting screw. The motor does seem to run noisily.
Is it possible to calibrate out the error? Unfortunately robotshop has been out of stock for more than a month or I would just buy another one, and the ones I have took 3 weeks to ship from the US so I am looking for a software solution.
Thanks for reading!
EDIT: I notice that the QPPS per motor is different in Motion Control studio:
I have also experimented with the PID, not much seems to change it. Using a set amount of clicks to move through, one wheel always advances slightly more than the other
