Would Like to Create a Calibration Benchmark Database



I have been working on Holey Triangular Calibration for a while. Because there are still a few missing elements, it is not quite ready for everyone to start using it.

I would like to create a calibration benchmark database, so there is some baseline for Holey Calibration. I am thinking it could be just an excel spreadsheet with everyone’s benchmark result, with the addition of some metadata like process (e.g. Triangular or Holey or Optical) attempt (e.g. first was mediocre vs. second try was better)

I can review the forums to find where everyone has posted their calibration benchmark result, but if everyone could attach any historical calibration benchmark data to this topic, it would help quite a bit.


Accurate MaslowCNC manual calibration, how to

1 Day, I need to bump this important post up. Sorry, but I’m not.
Missing heavily is statistics (from my limited point of view).

List of variables?
For a start:

  • motor distance
  • total sled weight (how else would you calculate chain sag)
  • angle of the frame
  • distance motors over the top (better bottom) of the sheet


You could just generate a Google sheet and share it with fields for everyone to report what they are getting…
