All the parameters and settings had been wiped out, I'll not discuss how (chair) .
The machine is back up and running except for one small thing.......
It has to be switched into "Manual" mode to open and close the chuck.
Before the wipe-out it wouldn't bar pull, it would interlock alarm on the next line after "M69".
Even if it was "M68" to immediately close the chuck.
Any info pertaining to the chuck parameters would be greatly appreciated.
Param #s, bits and their corresponding functions.
How our back-up was missing this is beyond me.
