Re: Lead Screws Spinning Out Of Sync
The proper solution is to mechanically link the two drives.
Failing that, PID position control will probably work.
Simply calibrating the motor controllers will probably make it better, but will not fully solve the problem - motors and assemblies are non-identical and small differences in motor output and friction can contribute to significant differences in behavior.
