Fix for errors when trying to add a new machine definition

[jdow749]

Cool project! Tried to follow the intro video using Blender 4.21 and got the following error when I tried to add a new machine definition for my Shapeoko 4 XXL.

Looks like a commit last month changed these (and some other) variable names and broke this. I updated to the new names where needed. Hope this helps!

Hi @jdow749 , thanks for contributing the code - development primarily happens on @pppalain or @SpectralVectors branches, with changes pushed here once they stabilize. Apologies, we should do a better job of letting people know where to submit Pulls.
It looks like the Preset Operator has already been patched, but when I checked the Preset files themselves there were a number that required both fixes you posted here, so they have now been updated and will soon be pushed to this branch.
If you're interested in contributing you can join the Matrix chat, or submit Pulls to @pppalain or @SpectralVectors where they can get worked into the experimental branch before moving on to main.
