Leveling the bed in software is easy. I already have that on lockdown. The problem is that Simpson has a slightly warped (only noticeable on parts over 100mm) coordinate system and it is hard to know what values to tweak in order to remove the warping. The purpose of the webcam calibration will be to get a 3D (not just 2D bed leveling) map of arm positions and xyz positions. This way even a poorly assembled Simpson can produce nice square parts of the correct dimension. (To be clear, I currently have Simpson dialed in to +/-1%.) The only requirement is that the machine has repeatability.
Dream:
Get a Simpson kit.
Assemble the Simpson kit. (preloaded firmware that is approximately right.)
Run the calibration routine with any old webcam (The FOV will have to be determined first.).
Put the new calibration numbers into firmware.
Print. Be happy.
