Help needed: Software setup for 4-axis tangential stone cutter (Mesa) was created by souh-hil
Hi everyone,
I’m building a 4-axis CNC machine to cut marble and granite slabs. It uses a large vertical diamond disk, and the A-axis swivels the blade to follow the cut direction . I’m using a Mesa 7i92 for the control.
I’ve built several plasma tables before, so I can completely handle the mechanical and electrical sides of this build. However, I have no idea about the software side of it. I’ve always just relied on the Pncconf wizard and have never manually edited HAL or INI files.
Could someone point me in the right direction for the software setup? Specifically:

Could someone point me in the right direction for the software setup? Specifically:
- How to configure LinuxCNC " A-axis that automatically follows the X/Y path"
- How to set up the CAM software so the cut is perfectly to size without the top of the blade overcutting the part.
Any examples, component recommendations, or guides would be hugely appreciated. Thanks in advance!

1 No.
2 No. but...
If i understand correctly, it is a bridge type CNC that turns the head where the circular saw is mounted, so that strictly implies no A axis moves while the head is down into material.
Basically, it can not cut curves or rounded corners.
It should be easier to just use a text editor and do gcode manually, or if you have repeatable dimensions, do a VCP panel with a choice of cuts preprogrammed.
Also strictly requires interlocks to prevent anything (auto, manual, MDI) to turn the head if the head is under a certain value where the material can be, those saws cost a lot, and forcibly stopping such big motors is never healthy as you have about 2-15 seconds before it permanently retires. With smoke.
