Hdu depth inconsistencies

what drives do you have?

The pinion and v rollers are tight.
I have a new collet.
The track is clean and lubricated.
I have even changed out the computer.
The wiring is in place correctly.
I ve even used a dial indicator so see if theres any change in the z depth and position in the beginning of a file and after and it goes to the same place. The depth on the files are all the same so no variation there.

do you have gecko 210's or 212 drives with the multiplier attached?

we have recently had to convert 9 machines back to 201's because of this.

So you are saying all movement on Z test is consistent and accurate yet when you cut real HDU files the depths vary from one location to another. Is that correct?
Quite strange?? I would suspect something in your electrical system or file but you say the file is good. Did you verify the code is instructing the Z to cut the same depths everywhere?
a 1/16" variation on the same sheet is huge.
Do you have some large tolerance settings in your design files?
I'm stumped, sorry. But very curious what you finally isolate the problem as.

I have the same problems.
I try to simply not pocket too much.
I try to design with a texture or wood grain so I won't have that problem.
