Swappable CNC/Laser engraver

Just to be clear, the V1 has firmware for the SKR Pro 1.2, not the 1.1. I think the chart is still accurate for differences.

I am based in Europe it’s somewhat harder to get the imperial measurement bolts, which I understand fit better on the printed parts

For the Primo (latest) version of the MPCNC, all bolts are metric. Here is the current parts list for the Primo.

As for the SKR 1.4, if you are comfortable with modifying firmware settings, flashing firmware, and perhaps working through problems, I’m sure you can get it working. I don’t have an SKR board, but I scan most of the posts that come across the form. And I see posts like this one where the builder had to do some work in order to figure things out.

I was not meaning they needed to be mounted at the same time, but rather that either could be mounted to the “fixed” part of the z carriage without needing to make a change to the that fixed portion

No problem there. The only issue is whether you can find a mount already modeled on Thingiverse for your specific laser, or whether you will have to model one up. I done a couple of mounts, and they are pretty easy to create.

And of course the SKR bundle is not in stock

I remember a post recently where more of a couple of kinds of boards is expected soon.
