Does anyone use the M670 command and G1 P parameter?

[dc42]

I am looking at changing the way M670 works so as to make it easier to implement over CAN. The change would be that M670 would no longer take a list of pin names in the C parameter. Instead the P parameter would be restored and this would be a list of GpOut port numbers that have been assigned using M950.

Is there anyone out there who would be adversely impacted by this change?

FYI for those like myself who don’t have every G and M code memorized:

M670: Set IO port bit mapping
Parameters
