I'm trying to use GRBL 0.9g on my own board with the Carbide Motion

I’m trying to use GRBL 0.9g on my own board with the Carbide Motion software but it isn’t seeing my board. What baud rate does the nomad board typically use? I’m at 115200 and I get the “cannot connect to nomad” error.

Version 2?

Version 2, I downloaded it just today.

Just a guess, but probably expecting a different string for the handshake. GRBL default is something like '[Grbl v0.9i ‘$ for help’]’, but carbide motion is expecting something like ‘CarbideMotion’.

I’d suggest on open source solution, like chilipepr. http://chilipeppr.com/grbl
And don’t miss the G+ chilipepr community

I’ve tested and like chilipeppr, but I’m always looking for different software.
I looked in the GRBL github and it doesn’t seem to have anything special about the startup string for Shapeoko3.

If anyone has specific info on the startup string, please let me know.

It wouldn’t - Carbide3d forked GRBL and added some special sauce or something.

This might help, maybe: https://github.com/grbl/grbl/search?utf8=✓&q=GRBL_VERSION

yup, I’m using 0.9g, they use 0.9i. —EDIT, Actually, I uploaded 0.9i built for SO2 and it fails. They must be doing something special after all.

I would suggest bCNC instead.

@William_Adams Thanks! this looks awesome.

The “CarbideMotion” welcome string is holding me up. I don’t feel like compiling GRBL and changing it myself, so I’ll bypass their software and look for others. bCNC looks great as does grblgui https://github.com/cody82/grblgui
