Trying to make sense of camera calibration.
I’m trying to use it on a piece of stock that’s 23mm thick and can’t get it to line up at all.
I did some tests and printed out a grid to see what was happening:
I did the camera capture on the paper flat to to the bed and then using that I arranged a smaller grid and laid out some letters to use to check:
Those results are acceptable (although vertical is off a couple mm but I can adjust for that):
Then I tried a camera capture of the grid 24mm off the bed. The grid starts to show some problems (center squares aligned, but outer squares are off, had to change size/shape of letters )with alignment :
Ran a pass and it’s completely off:
Am I missing some adjustment or way to compensate or calibrate for a thicker piece? Something wrong with my camera? I assume that if I tried to do the calibration on top of a raised piece that the toolhead would slam into the piece.
Any suggestions?
