lcnc-suite — web UI for LinuxCNC

Now that sounds pretty neat! I take it your Arduino Q contains literally both the mini-pc running Debian 13 AND the motion controller grblHAL STM32. The entire system on one compact little Arduino board the size of Arduino UNO!
I bought one of those Arduino Q when they introduced them. I'd love to unpack it and try that, but I'm currently working overtime on another big project, that should be done in a few more weeks...

i just thought about this, a interface without the load of the display manager, searched i came to your project. I have a rpi4, a 7i90 and a 7i84, a 26pin conector and a sort 50pin cable. 7i90 flashed to spi. every thing to test it. i reply with my feedback, great project.
