    Hello,

    Coming so close to outer perfection on the calibration of my Workbee, I noticed as I hope you will see in the attached video, that as I move the gantry in the Y directions, the stepper motors are not triggered at the exact same time so that as I try to move in one direction and then move in the reverse direction, you can notice that the farthest stepper motor is on a slight vacation as it sort of rocks itself where it should go. I checked my belt tensions.... They are fine. I checked that the weels were not binding.... They have eccentric spacers tuned not to tight. Can someone throw in a suggestion? Thanks.

    Checked grubscrews on pulleys, added loctite? Looks like pulley slipping on motor shaft

    I feel like I'm in confession.... But yes Peter, I did, based on your previous intervention. I will check again
