How to obtain highest camera accuracy?

If you’re pointed at a small area, and the camera is hard mounted so it cannot move it’s possible. The accuracy of the camera is only going to be as good as the best mechanical accuracy you have on whatever is holding it - for example, if you were to drill a hole in the acrylic lid directly over the bed center, that would mean the camera angle and lateral position could not move, which would be ideal. That said, if your hinges have half a millimeter of slop in any direction, that will translate into half a millimeter of inaccuracy with camera placement too.

The head mounted camera feature should allow for better accuracy, especially with larger lasers. There hasn’t been significant progress on it yet, but I’m hoping to get some time in soon.
