Rehome when opening another version?

Have these other versions of PC-DMIS been used in the past? I'm not entirely sure on this, but are the machine parameters correct?

Press F5 and under the Part/Machine tab and see if there's anything that sticks out on the versions with offset coordinates.

Has the machine ever been homed on them?

What are the versions you use and the last time you've used them?

We use 2020R1 and 2020R2 on our machine without homing between them. Both versions are mapped to the same probe directory. 

Once the software has been set up the first time for machine parameters and probe rack locations it doen't seem to make any difference. Also when switching between them it does not prompt you to re-home the machine. It will ask you what probe is loaded at times but otherwise seamless.

Yeah that makes sense. I just wasn't sure if it keeps all parameters shared between old and new versions, like 2015 to 2023, since they added that machine environment thing

Hmm, maybe I need to share the same probe directory between the two.  It appears that this CMM was originally installed with 2015.1, then upgraded to 2017 R2, then upgraded again to 2023.1.  All three are still installed.  I believe it's the original PC.  I'd like to be able to run older programs in the version in which they were written because if I migrate them to 2023, it does a whole lot of validity checks and there are a LOT of invalid GD&T commands in these older programs that Xact Measure allowed, but GeoTol won't.  I'd like to be able to fix them, but that would require fundamentally changing a lot of the programs.  

No idea what you're talking about there..

However, on that note, you should be able to take them to 2020R1 with no issues, and then take advantage of its more modern features. 

We still have many programs that have not crossed over that threshold for the same reason you do, we tend to leave them until the parts rev and then incorporate the geotol/xactmeasure mess into the update.

I would NOT share the probe file folder to all versions.  If you haven't noticed, Pcdmis will pop-up a warning about using a probe file made in a previous version, "DO YOU WANT TO UPDATE THE PROBE FILE TO THIS VERSION?" kind of thing.  Honestly, I have no idea what could be different between versions for the probe file, but I don't think you will be able to use the probe file in an older version if a newer version updates the probe file.

I can only speak from my experience with 2020R1/R2, as that's what they were using when I started here. Its used on every piece of equipment and computer. If there is a conflict between "version years" that's a different thing entirely. Seems that 2020 plays nice with itself.
