Question #: 14891

Question: Developed an issue, when moving the y-axis it started to move, than stalled and sounded like gears grinding. Had to re-zero the y-axis. Using the USB controller with Mach3 software. What would cause this?

Current Solution

The velocity is too high and/or the acceleration is too high and/or the axis is not calibrated and the motor is trying to move too fast, or trying to move too much inertia that the rated torque cannot overcome.

The recommended action would be to lower the velocity and the acceleration and do a calibration using the "set steps per unit" wizard on the settings tab of Mach3.

Once the calibration is completed and you have confirmed that the motor is moving the correct distance in reality compared to the DRO (digital readout) in Mach3, then you can increase the velocity and acceleration in the motor tuning section of Mach3 (config -> motor tuning).
