Thanks Fixittt , what is really cool is 1.5 hours into the job the tip of my .25 V 30 bit broke ( they are needle sharp,maybe sharper even)
It broke maybe .02 off the tip, definitely noticeable in the carving. I stopped the work re zeroed my Z axis, backed up 20k lines of code in Mach3.
started the code again. I can not even tell it happened... Thanks to MACH3 ....
