Regarding UVW as axis 6,7, and 8

I have seen many mentions of UVW being "arbitrarily-assignable".

I have also seen many mentions of them being considered "parallel" to XYZ. Is this for the sake of displays?

I am trying to conceive some automation projects in my shop and would love to have 3 more axes that I could utilize independently from my use of XYZABC.

For example, I have a bunch of parts to make for a project. I would like to first build a little part-loader and activate it similar to how M6 is used for a tool change.

I like the idea of having UVW -- via GCode -- to drive this part changer.

Can UVW truly be used as 3 "arbitrarily-assigned" axes driven by GCode without having any affect on XYZ ?

Thanks in advance.

Hi
linuxcnc
is PID orientaded
so you can also have a NON Axis letter Joiunt
moving by gcode
saying M150 Palet 0 in
M151 pallet 1 in
...
behind the Mcode is a simple Gcode that moves the changer

but you can also configure 9 Iso axis and only show 3 xyz
there are many things idees you can go with

you may also look on YT linuxcnc pallet changer

Thanks for the answers. I was with you up until you wrote, "trivkins".

Is "trivkins" refering to the typical operating mode most people use or is this a mode I need to use in order to use UVW as I mentioned?

I have seen the word "trivkin" many times before, but I never really looked into what it exactly meant.

You are right, of course.

I was hoping as much, as I've finished with the part loader and can't wait to run it.

I had also been thinking of possibly using 2 different LinuxCNC boxes and tying them together with a simple I/O handshake using M codes to perform the I/O.

Using UVW is better.

Thanks again!
