Hi all,

Came in on Monday after a weekend out of the shop, fired up the Hardinge Conquest GT and was greeted with a '911 RAM Parity Alarm (4n+1)'

Tech guy on the phone said there was no way out other than Reset + Delete on start up to gain access to the motherboard and rule out that the motherboard wasn't FUBAR.

This does indeed load up and required me installing all my parameters again, no problems there, restart the machine, all looks great except now my collet open / close button doesn't do anything, also means that it won't start the spindle without the collet being closed.

Apparently there is a procedure for regaining the collet working, requires the air being turned off and then a parameter change and then turning the air on. Unfortunately I can't find anything on it, so could anyone shed any light on the situation?

Thanks in advance!

Andy
