Centroid Community CNC Support Forum

I recently upgraded to CNC 12 V5.20 and now have received this error.
Problem is I don't have a door switch.

If you updated to v5.20 specifically to gain some of the new features that are only supported in new PLC programs (e.g. separate rapid override, diagonal jogging on the VCP) then you are stuck using a new PLC program. In that case you can either edit out "SafetySwitchInterruptStage", or invert INP8, or wire a jumper to INP8.

If you were happy with the PLC features you had before, and just wanted to have the latest CNC12, then you can simply restore your most recent Report from before the update, since that will contain your previous PLC program and its supporting files.

If you want the new PLC-based features, but you also want to retain the spindle brake delay timer (Parameter 960) that I added to your previous PLC program four years ago, then you will need to do some editing to merge the custom features of your old program, into the new program.
