Definitive guide for Shapeoko?

[ctdodge (Stan Krupowies)]

I have a Shapeoko 3XXL and I just purchased a Jtech 7W laser kit for it. I haven’t installed the laser yet but before I do I’m trying to find a consistent description of GRBL settings that need to be changed.

From what I can tell I need:
$30=255
$31=0
$32=1
$10=0
G10 L2 P1 X-812 Y-812

Is that everything? And I think I need to reset when I use CNC so I would have:
$32=0
G10 L2 P1 X0 Y0
$10=1
Is this correct?

So it would make sense to have a “Use Laser” macro that does the first set and a “Use CNC” macro that would do the second set?

Please let me know if this should cover it.

Thanks
Stan

The link I am providing is the definitive as it is produced by the nice folks over at JTech. https://jtechphotonics.com/?p=10204

Scroll down until you see a section about setting up the macros for their detailed instructions.

That looks correct, yes. The setup is covered in detail on this page: https://github.com/LightBurnSoftware/Documentation/blob/master/CommonGrblSetups.md#common-grbl-setups

The first paragraph hits all the ones you’ve specified. Though the $30=255 setting can be pretty much anything as long as it matches the S-Value Max in the Device Settings. The controller and the software just have to agree on a number - it matters less what the number is.
