GRBL generic post not posting M5 (spindle off)

[Anonymous]

Is this a command we can add to the post. I just put a new spindle on my machine that can be controlled via the program and the post for GRBL doesn't output an M5 Spindle off command.

If I knew where to add this to the post I would do it myself. I have been manually adding the code. ;D

Thank you
Tim

Where and when does it not do this?
I mean we need more info on what it is like now and how you need it to be.

Sure, below is what fusion is currently posting. after doing some reading I think the M30 should turn off the spindle and reset the program. I belive there is a bug in the GRBL firmware that is not letting the M30 process correctly. I understand there should be an update to the firmware in the next few weeks. maybe a post change is not needed.

As long it is not fixed in your firmware, use this post instead, it will output M5 at the end of the program.
