grblHAL It seams to work but....

[stefan63]

grblHAL seams to work (Have nott yet fully tested all features) however top left header says "grbl: not connected despite grblHAL is connected and works :0)

To Reproduce
Steps to reproduce the behavior:

1. connect controller with grblHAL firmware
2. Conect it
3. Home all axis
4. Jog or run G-code

Perhaps you can show me the start-up message from grblHAL? Just check the shown checkbox before connecting.

Thanks, that helps to fix the issue: "GrblHAL 1.1f ['$' or '$HELP' for help]"

Great I realised that the footer kind of correctly reported grbl connected!? Den fre 19 dec. 2025 kl 18:17 skrev Sven ***@***.***>:

I love your work and admire your skills but like many techy guys (I´m guilty of) the user friendliness is 2nd, however you are among the ones that partly succeeded. If you don´t mind me saying the UI of the "new" gSender looks really nice but is lacking in a feature that I love ; Surface mapping for PCB work. Please reach out to them and offer your profession and skill. They would love it. Kind regards/Stefan stockholmviews.com Den fre 19 dec. 2025 kl 22:48 skrev Stefan Lindgren ***@***.***>:
