Trouble with Z-Zero for PCB making.

fixing it to the edges it will always rise in the center, I also tried with the vacuum the one in the center instead pulls it down too much .. the best solution is the milled plate and double-sided tape. I use "eurocel 50 x 25" but it is too strong and boring to remove, they told me that there are types that are less strong on purpose but I have not tried it yet.

Exactly what I mean.... I tried a "chinese" one; not really strong (I can detach it easily enough), but is so sticky.....At the end you waste more time cleaning the adesive debris than milling the PCB......

Reading back, the adaption is in the G-code as Z moves? Then run the G-code with the spindle turned off and check the dial indicator reading as it runs around the board.
You could do the probe, then mount a dial indicator in the spindle and jog down to a constant Z and see what the indicator says.
