purchased a VF4SS and VF6SS under a year ago and I have already tossed some parts because the probe on the VF4 somehow lost .018 in it's Z value.....today the VF6 had a positive value for my probe height.

While I disregarded the first problem to me somehow hitting a button in error....I know for 100% positive that I in no way changed the value of the H for the probe today. I just did not hit enough buttons to make it possible.

on the good side the value was such a significant difference that when I ran graphics it had a z over travel error....but I can't even tell you how pissed I would have been had the value been closer to the original number and enough to slam my spindle down into my part at rapid speeds.

I don't know what the fawk is going on with Haas control software...but the bugs in it really need to be addressed. our old machines I trust a hell of alot more than the big money stuff recently purchased.
