M18 vs M84 - same thing?

[lael]

I'm running through the example macros provided here: https://github.com/Duet3D/RRF-machine-config-files/tree/master/DBotCoreXY/x0r-wifi-RRF3/macros

and noticed that the macros are frequently using M84 without an S parameter [idle time in seconds] (Stop Idle Hold) to disable steppers. Is this actually doing the same thing as M18

Gcode references here:

Hmm, I dunno. But those are my macros and I can confirm that M84 by itself does let me move the motors freely.

Thanks! I appreciate the macros! It's super helpful to have a framework to begin with. I'm working through them now, and then I'll create that mesh.g and test it properly... may have some more questions when I get there

Yes M18 and M84 do the same in RRF.

@dc42 Thanks!
