Testing PINDA Probe

If you are suspecting an issue with the PINDA probe and whether or not it is functioning as expected, please try the following:

  1. Connect the printer via USB and Pronterface
  2. Ensure the nozzle is clean and the print surface clear of any obstructions
  3. Issue a "G80" command, this will start the mesh bed leveling process
  4. Once the process is complete, send a "G81" command, this will report out the interpolated Z values for a 7 x 7 array that composes the mesh bed.
  5. Repeat the process at least 3 times
  6. Compare data points for each reported 7 x 7 array.

You want to make sure there are no large deviations (>0.2) between each point of the array with each interpolated Z value. Remember that each data point is a position, and you should compare that same position with the same position of the other reports.
