run single block without the tool to determine which line causes the problem
looks like something to do with tool length offset
run the program without the 'T1 M6' to see if it does the same thing

My understanding here is that homing doesn't actually set the current
z point as zero. Touch off is what does that.
My normal sequence is to power up the system, home all of the axes...
this simply performs the calibration for the actual machine position.
Load my matierial to cut and move t
d even when you close EMC - not something I
would have guessed to be honest.
Thanks again for the great response Chris!

I watched the video - very useful to show what's going on. I do not
know anything about cambam but the gcode does n
I have no idea why this is occurring but it's driving me crazy. It seems the
very first pass I do in an operation is resulting in it burying the Z-axis far
deeper than it should. I've been able to reproduce this consistently. I've even
created a little video that shows it happening:
