How do You mean - count the same way? If I understand correctly, then I tested this: If both motors turned clockwise Then rawcounts increase in positive direction for _both_ motors. The thing is: For working motor - turning clockwise is movement in positive direction. For nonworking motors - turning clockwise is moving in negative direction. I have: INI file scale values (input, output scale) with "+" signs for working motor; INI file scale values with "-" signs for nonworking motor. Bldc scale value for all motors is -8192 Should I also have Hall pattern changed so that it is exactly opposite to working motor? What is _recomended_ approach for reversing the direction? I also tried Your suggestion: setting all PID parameters to 0 and choose small P. I set P to 3 and turned motor by hand. The resisting torque increased. It felt like gradual increase. I turned it both directions, it felt the same strength of resistance. I was able to turn it approximately full turn in each direction, it did not cog or jump anywhere, but returned approximately to starting point.
