Hi,

We are using EziServoST 86XL motor and driver for the X axis of a prototype CNC machine, we made some upgrades to the gantry and now we have a problem with the motor accuracy, the problem is;

in +X direction the axis moves more than it is commanded by the controller, error increase with the movement, for example it moves 0,5mm more when the axis commanded to move 300mm but it returns to the 0 point without an error. We could not fix this by adjusting the controller, actually this error is fixed, whatever we adjust in the controller error keeps the same. There is no mechanical error in the axis which can cause this much error, Y and Z axises are working normal without any error and these axises have regular stepper motors.

There is an position gain and in position adjustment on the driver but in the manual there is not enough description about these adjustments, what are they? can they fix this problem? and if not, what can cause this much error in this axis? thanks.

The controller is Mach4 PC based controller with 4Mhz Ethernet Smooth Stepper motion controller, resolution set to 7200 on the driver.
