It moves down fine and if I set the jog rate to slow jog rate to 90% it will work fine but nothing more than 90% and it will lock up again.
It does this when trying to run a program as well when the machine attempts to move to rapid clearance height it will lock, the DRO will get out of whack and the program is shot.
Running Mach 3, did an upgrade yesterday to see if that would fix it, no help. full reboot and shutdown of all systems no help.
Have made no changes since thursday when the machine ran fine.
Any suggestions on what the issue may be and some trouble shooting tips.
Thanks
