Hi Folks,
I have a bit of an odd use case. I have an RF45 clone machine, and given the position of my z crank, I don't ever want to touch it, and would prefer to use the Z controls of LinuxCNC. However, I want to maintain manual control of my X and Y crank for the occasional manual operation.
Is there a reasonable way to make LinuxCNC control my Z, without getting unhappy about following errors on my X and Y, without having some kind of "modal" behaviour, where it "snaps back" to the commanded position when I exit that mode?

One option is MPGs, you could install two MPG encoders.

That is a very good idea as it eliminates many issues caused by other methods regarding feedback and jumping to position and ...
There is another similar topic going on here on the forum but i do not think this idea was presented there, i will double check if i bump into it.
