XL and Core Belt. Are they the same??
Does anyone know if the belts used on the XL are the same as used on the Core One, except for length? I would like to use the XL belts on a Core One for easier installation then trim to length.

They are the same (2GT belts, 6mm wide, 2mm teeth), but then my question would be why? Are you having a problem with your existing belts? If you are finding that the provided belts are "too short" then you are probably doing something wrong with the routing.
RE: XL and Core Belt. Are they the same??
It is more about my hands. I have big and arthritic hands. I fumbled with the short exposed teeth a lot, and it is frustrating and time-consuming. I don't mind paying for longer OG belts then trimming them. I spent hours getting the originals installed, and by the time I had them working, my hands were sore. I resorted to purchasing a roll of GT2 that looks the same, but I am having a layer shift on large, wide prints and cannot get the Y-axis to pass, so I am going to replace the belt material I purchased with some OG Prusa belts for the XL just to see if that is my problem.
THX for help.

Usually if the Y axis is not passing and you have layer shifts, that means either the belts are too loose, the gantry is bent or both. I would start by completely loosening the belts and check that the gantry is still square. Then follow this guide closely: Adjusting belt tension then most important point is that the gantry needs to start off square/parallel to the front of the frame and the belt tension screws need to be tightened by exactly the same amount and never independently.
Until the Y calibration passes, expect layer shifts.

That is my next item. I want to break it down and make sure everything is still square.

Yes, the $13 each XL belts are the same and 70cm longer than the Core One belts. The works out to about 1.5 cents per mm for the extra 700mm. Where as the Core One belts are .02 cents a mm for the original belts (????) I just couldn't deal with trying to get 4 teeth to stay put when tensioning, and I was tired of support telling me it was the replacement belts I had installed so they were long enough to work with. So I blew $30 to buy 2 XL belts and have them shipped to put on my Core One. Just my 2 cents, but having an extra 20mm or so made running the belts and installing them a 5 minute problem instead of an all night problem.
Now I will get back to support trying to solve my Y-Axis failing. Prusa...it would break you to add 20mm to the C1 belts and let us trim them off.

I understand your issue with mobility etc. At least on these forums this is the first I have heard of this issue of the belts not being long enough.
Anyway, glad you were able to resolve this.
As for your y axis calibration failing, you must manually bend the side of the gantry that is not square (parallel) to the frame. Once you have done that and have properly tensioned the belts, then y calibration will pass. You can follow the guide I linked above.

It's square! It's square! It's square!
Y axis will not pass. I think I have done it all.

How did you determine it was square? With the belts loose or under tension?
RE: XL and Core Belt. Are they the same??
The gantry is square and touches both sides properly. Belts are T 98 B 94

Is the gantry square when the belts are loose? That is my question.

See @mccluskey1's post in the parallel thread and my reply. I think we have found the underlying assembly issue; correcting it should resolve the Y axis failures.
RE:
Thanks Jürgen, I see that thread.
I'll post on this thread for posterity. If the belts seemed too short, then as pointed out in the other thread (and in the second post of this thread), that they were routed incorrectly. Buying longer belts only made finding the original problem worse.
