About electricity cut, you suggested it…
Your last question is interesting, I didn’t think at it.
If only one motor misses one or more steps I will get 2 axed not in square and then theorically an ellipsis instead of a circle, but, missing the steps in the middle of the cnc program I would see a different path for the subsequent layer passed by the end mill. My ellipsis instead is identical on the three layers passed by the end mill. And I’m not sure I should get an ellipsis instead of an open curve.
Anyway, let’s return to my original question: is the play on the axis shown in the videos normal?
