Have taking this thing apart adjusted everything multiple times still the same problem starts cutting right and then towards the end it gets deeper I’ve make sure the waist board is level and things are squared up what is clamp down nothing is moving cannot figure out what’s going on if anybody has an ideal please help all ears.
A level machine dont have to = Z is truly parallell with your wasteboard.
Your discrepancy come from change in elevation relative to Z reference.
The most common fix for this is to add a 2nd layer of wasteboard and perform a skim cut, skimming the surface, milling it down to a uniform level relative to Z.
Another possible scenario could be that you have lost some steps on Z, causing it to ride lower and lower, but my money is on the first
