Thermal Shutdown Response? #753

Open trbLeeciN opened 4 years ago

trbLeeciN commented 4 years ago

Hi there, I searched all issues, I couldn't find or I missed my problem. Are there any response message or alarm message if stepper driver got thermal shutdown? Thanks.

No.... there's usually no input back to the processor that Grbl is running on that the steppers have a problem.

Edit to add: there is a reset/abort input; but I've not seen it actually hooked up to anything on most builds. If you have a suitable signal, you could route it into that pin; and on overload have it halt Grbl.

However...

If you are having thermal shutdown issues; you really need to sort that out at the hardware level (fan? heatsink? liquid cooling, the way high-performance PC are setup?).
