Each consecutive pass will be 0.25mm up on the Y axis. X axis is perfect.
Seems small but when you do 5 or 6 passes the difference becomes noticeable. End result is a cut that is stepped or not 90 degrees square.
Also causes the bit to increasingly vibrate as you go deeper since the cutting edge is increased on one side.
Anyone have this occur to them or have an idea on how to solve?
I’ve calibrated again and have an extremely accurate setup at this point, but maybe
