Yeah v interesting answer.

>>> You can setup optical switches, accurate to about 1-2 microns, for less than 20€ each.

Would love to know which ones?

Probably the same ones that exist only in Hanermo's mind.
He loves posting all this on various forums, but has never yet produced a single bit evidence any of his machines exist anywhere other than in his own personal universe.

As I said, the bottom line is actually putting a piece of steel etc on the machine and cutting the damned thing. A proper test piece will exercise the machine in all axes, with internal and external surfaces, circular and flat features etc.

Effects like backlash and machine flex happen when cutting real parts rather than on unloaded machines cutting air. Measure how the test piece compares against the model including circularity, flatness, perpendicularity, dimensional accuracy etc. It would be interesting to hear how the lunchtime legends got on....
