I took the X axis apart to align the cars on the lineair rails. Z axis behaviour unknown to me.
Just be sure to remember to re-align the ATC, to save some of your ISO30 holders.
Btw, I made a cheat-sheet for measuring the Z and Y position on the tool forks (inline ATC only) so you only need to measure 1Z position and 1Y position. Just use a dial indicator to measure the tools position in Z height and Y depth. Works like charm on mine. Only need to measure X position for each fork and all the other Y/Z values are calculated from 1 measurement, on fork 1.
