I realize I’ve been blowing the troubleshooting area up quite a bit lately, apologies. I have to admit that I’m kind of at a loss. I have run several calibrations, large and small. Today, I started from scratch just to make sure I wasn’t missing something. The first calibration I ran was 800x800 in a 5x5 grid and I got a fitness score of .95. I ran a test cut of a 200mm square and it came out 185mm X 208mm. I reran the calibration this time 500x500 in a 3x3 grid and got a fitness score of .56 and cut the square and it was identical… 185mm x 208mm. I’m a total CNC beginner but my gut is telling me that there must be something simple I’m missing because the end results are identical. Just in case, here is the serial output from the last calibration and cut. If anyone has any ideas I would really appreciate the assistance. I realize this is a long shot but if anyone is in the Olympic Peninsula area and has figured this out and would be willing to take a look, let me know haha!

Update 6/29: Ran a few more calibrations to see if I could improve the performance. I ran another large grid and another small grid when that one failed. I got fitness at .69ish. Tested the box again and got the exact same result… 200mm box cut a 185mm x 208mm. At least it’s consistent in its offages.

It is quite consistent, but it’s also quite off!

It does seem like there are cases where the math can converge on an incorrect value and we’re not exactly sure why. Since the calibration process uses the last successful calibration as a starting point, maybe it’s just finding the same incorrect locations for the anchor points each time.

Can you try deleting your maslow.yaml file and uploading a fresh one? That should make the process start fresh without using it’s past calculations as a starting point.
