I am experiencing something weird when zeroing Z with my touch plate.
Usually the bit will retract 50.8mm (2”) after touch off, this is also what the setting is in Mach 4.
Just recently though, it started to cut shallow and I noticed that the bit only retracted 38.8mm instead of the usual 50.8mm, My cuts were also left shallow by 6.13mm.
On testing, I note that when starting the machine and Mach afresh, the bit will retract the 50.8mm after zeroing, but will leave the cut 6.13mm shallow, and then the retraction height is again only 38.8mm I can verify this depth by touching the bit to zero on the table and this is the difference.
If I just set the tool zero manualy by touching on the table and setting the Z to zero in mach, the cut is perfect.
I haven’t updated any software recently and the computer is quarantined from the internet and the Avid setup software (to turn off many programmes and settings etc, can’t remember what it is called) was run when the machine was setup.
The machine is a 4’ x 10’ Pro has NEMA34 motors and is approx 5 years old and it is run in a semi production mode, e.g. most every day, but was certainly run harder it’s first few years.
I have scratched my head trying to figure out what may be the issue, I’m convinced that it must be a software thing, but of course may be way off?
Hoping that someone can point me in the right direction, for now I can continue working by zeroing manually but have gotten so used to the touch plate that I really miss it.
Thanks
