So I am working on something completely different while background thought processes continue to ponder a better solution for materiel setup and alignment on the tables.
I get to thinking that I already have 2 torches set up and ready to go, one for my 1650g3 and the other for my 45xp. I saw that one of the users here used a picatinny rail and scope rings for the machine torch and went with that idea. I picked up some cheap scope rings with large hex nuts that need little torque for this application and with the through hole in them I can stick an allen wrench through it if needed.
Anyhow, back to the problem at hand…Lasers have been approached from multiple different directions but none that I saw involved removing the torch from the gantry to mount a laser that way…
You see where this is going right?
Here is a laser cross hair mounted in a 3d printed 1" housing - either remove the torch from the OE v clamp, or in my case, loosen two nuts, remove the torch, install the laser, and regardless of torch height, x marks the spot. Get set, remount the torch (Picatinny rails pretty much guarantee you are as square as it was when you removed it). 1/4-20 set screws to zero position on x,y, regardless of height.
I went with a more expensive laser this go because I can use the mount elsewhere, and the power supply as I don’t want to crack the Langmuir box just yet to tap into that power supply.

If you wanted to get fun, there are scope rings with rail sections on them Left, Right and Top, and quick release/lever lock.
My rail was mounted to the OE Langmuir torch base sans v clamp. Quite centered and parallel.
