Hi, terjeio, can grblhal be used for lathes? The lathes depend on the spindle synchronous threading function? Can I claim that grblhal supports lathes? #237

I don't have a lathe, I don't know much about lathes

can grblhal be used for lathes?

Yes.

The lathes depend on the spindle synchronous threading function?

No, this is optional - and not extensively tested. And only a few drivers support spindle sync: MSP432, iMXRT1062 and STM32F4xx (hopefully I'll soon be able to test the F4xx in my mini lathe). STM32F7/H7 should be able to handle spindle sync as well.

I claim that grblhal supports lathes?

I think so - up to a point. Radius/diameter mode and constant surface speed is always supported - the latter requires spindle speed under control by grblHAL, enabled by setting $32=2 (lathe mode). By enabling the controller tool table indexed tools should also be possible to use.
