found the problem was the shafts in the reduction pulley would turn almost a full turn then catch and then release. Know the opposite side is doing it. I dislike to have to use set screws to secure to a shaft as this would happen. And yes I did flatten were the set screw hit the shaft. First time setting pulse for movement right on the nose.

The drive seam to race each other for the lead. I have a x axis setup that works fine just the slaved y . each side fight for the lead. The gantry was Squared when started but each motor is pulling it out of square but will change from side to side . Flipping the cables had no effect

I have  stepper drives with belt drive reduced 4-1 . when drive take off start the same but seem to fight each other one going faster then the other then changing sides. you can watch it do it. Belts are tight pullys are the same size as well as the motors. Changed cables no difference. has to be in a setting in mach. Motor tuned the same.

Thanks Randy
