Hey I'm hoping to get some help with an issue I have created with one of our old machines.
Bridgeport VMC3020. The controller is Fanuc 21i.

When I try to enable parameter write it briefly changes to 1 then goes straight back to 0.

This happened after i changed a parameter 3290 thinking it would change Key3 so that i could edit a macro.
I also changed 3292. Now I am unable to enable parameter write.

Please tell me someone knows a work around for this?

Thanks in advance.
