Problem while pressing STOP with grblHAL on STM32 BluePill ERROR 3 and ERROR 9

Dear friends.

Here is the topic on GitHub:

I’m using a STM32 blue pill with a GRBL firmware called grblHAL. Looks pretty nice, and I managed to get it working with LightBurn, but not totally.

The problem is when I press the STOP button, I get ERROR 3 and ERROR 9, look at the GitHub topic indicated previously.

Is there a way to edit the GRBL Commands sended while we press the STOP button?
