Movement test with PuzzleBox32 Mini
06/02/2025 at 10:30 • 0 commentsGot the PuzzleBox32 Mini up and running with GRBLHal.
- Tested all limit switches (TL-W5MC1) and they are working!
- Tested the probing and it's working!
- Tested movements on all axis and they are working!
- Configured GRBL settings for correct direction, step sizes, limit switches
- Tested old PWM board - sent 10V back to the ESP32 and that was unfortunately (luckily this was done on a demo board, so it didn't fry the PuzzleBox32 Mini)
Next, the PWM board will be redesigned and made.
Most of all, the optical hole finding code needs to be updated to be more automatic (Baby steps...)

Fisheye conversion works... sort of
05/06/2025 at 14:13 • 0 commentsPlayed around with OpenCV for fisheye lens compensation. The new camera isn't ideal for this, but it fits better underneath the Z axis. Done the chessboard test and got some decent results from it.
Next step is to make a script for automatic centering the camera over the hole.

Hole tracking works.
05/03/2025 at 11:12 • 0 commentsGot the alignment hole tracking to work in a simple demo script using a cheap Chinese "microscope" camera with a decent lens.
Switching to another smaller camera with a fisheye lens, so conversion is needed.
