I'm trying to write g code using G02 and G03 with variables commands. It won't let me use a variable for the Z end position. The x end works fine. When I try to use a variable for Z UCCNC version 1.2111
will not load the program back from editor. It doesn't show any error just won't load program until I put the number back in then it works fine.

can you show the actual examples of what works and what does not work

This is the G code that works. When I replace the numbers for Z with the variable #2 then it doesn't. thanks

It would be much better if you post the code that DOESN'T work.
And what version of UCCNC you are using.

This is the one that doesn't work. I'm using version 1.2111

Looks like you need a G18 for an arc in the XZ plane?

I do have a G18 at top of g code

Oops, sorry. I'm so used to my programs having several lines of comments at the top I just passed right over it.

I can see there is a problem (is it doesn't work if you change Z-0.250 for Z#2)

but I cannot see why it does not work or allow the file to even load (I tried a few things to get it to work + load)

but just a side note, looking at the cut paths, I think you are going to suffer from tool rubbing because of the thinning of the cut path at the end of the cut.

It seems to be a bit complicated. (I tested on both 1.2113 and 1.2049.)

If I change Z to Y and go back to the G17 plane then all works fine:


If I load the original (bad) code and put a G17 before the M30 then it displays with the Z#2, but the arcs are in the bad direction and also leaving the X-Z plane:


If I use the original (bad) code and change Z#2 to Z-.250 then the arcs are in the X-Z plane:
