I'm trying to add a fixed tool length probe to my 3 axis CNC router.
I don't have an ATC or any way of indexing tools in my router, so I'm just looking to reference my tool changes against the first tool I started using.
So my current expected workflow will be:
1. Home machine
2. Get the initial tool length
3. Zero tool on workpiece
4. Run a program
5. Change tool
6. Get a new tool length
7. Run another program
Firstly, does that sound right?
I've been through the M31 script, and with a few minor tweaks I've got it to move to above the fixed probe location and touch off. It stops at the probe and everything is good there, but I'm not sure what it's supposed to do next.
The M31 script has G44 H1, but isn't that loading a tool offset rather than setting it? I've tried running the script as is, and it doesn't seem to update anything, the workpiece zero is still at the same point.
So I'm guessing I need to switch out G44 H1 for something else, any pointers as to what?
Thanks
