Pitfall in v5.20 mill update: WCS file lost

Oak, Allin1DC and MPU11 users should be aware: installing the v5.20 update will overwrite your WCS file with a new, blank file.

That will remove your software travel limits; zero out any custom return points (such as a fixed tool setter location, or the G30 Z coordinate for an umbrella or swing-arm tool changer); and zero out all your work offsets.

You can recover normal operation by restoring the last-known-good report from before the update, or by extracting the cncm.wcs file from such a report and copying it into the c:\cncm directory.

And, to forestall any "but you can't ever install CNC12 as an update" replies, yes you can. Only Acorn installations, with their heavy interdependence between the setup Wizard, custom VCP, and all-inclusive PLC program, have a "no updates" restriction.

I noticed yesterday that the v5.20 update will also overwrite any custom park.mac file in the c:\cncm\system directory, and likely any custom MPGMacron.mac files.
