Hi,
I have a 92 Mycenter1 and having problems with the tool change operation. In MDI mode I call up a pot number the machine responds, when I type in command M6 the pot drops down as should but the spindle spins at 1000 to 1100RPM rather than the slow RPM I’m use to seeing. Then the spindle stops then nothing happens no ARM movement. The same happens when a program is run.

Could someone shed some light on this problem?

Thanks In advance,
Eric
