My operator hit some button accidentally and now the tool length offsets are all wrong. We had a procedure written down for this which includes going to MDI > SET UP "Tram 0" "setup 1" "M37=0.0000" with a note that says
"Reset M37 for tool length set"
But it seems to not give me the option to change M37 (which is at some random number right now). Is there a switch on the back of the machine that needs to be enabled? Some kind of "parameter write enable" or "service safety" button? Please help asap!
Oops! Got it figured out. Parameter "M37" can be reset back to zero by hitting Mechanical Jog hardkey.
