Backlash Compensation

Calibrating Backlash Compensation

Now we can have OpenPnP run its automatic backlash compensation routine to make all head movements more accurate. Read the OpenPnP docs page about this step here.

  1. First, we’ll select the axis we want to calibrate backlash compensation for. Under the Machine Setup tab, select ReferenceControllerAxis x under Axis. Then select the Backlash Compensation tab.

  2. Next, click the Calibrate now button. The machine will go through a long routine (between 5-15 minutes) where it measures the machine’s backlash, and determines the best settings to account for it.

  3. When it’s done, you’ll see the output data from the calibration. We suggest selecting OneSidedPositioning for the Compensation Method, but experiment with the different options to see which gives you the best results.

  4. Perform steps 1 - 3 but with the Y axis instead.
