Is M92 modal?

[Esseff 0]

I believe that the M92 command is modal i.e. it is active til it is cancelled. Is this correct. As far as I can tell if I put it at the beginning of the g-code it should be fine the entirety of the program. Also not really how to differentiate between the two extruders. Does the M92 command effect both equally? If not then how do I apply separate values to the different extruders?

 

Thanks.

Btw this is for Cura 4 beta (although that shouldn't make a difference) and the printer is a Creality CR-X

The behavior highly depends on the firmware of the printer (and nothing else).

 

A recent version of Marlin can be build with enabled "DISTINCT_E_FACTORS" - but doesn't have to...

If the firmware supports it, you can add T0 / T1 options as with other commands (e.g. M104)

 

The recent version of Marlin (1.1.x) synchronizes it's internal positions after each M92 command on its own. For older versions you have to do this explicitly with a subsequent G92 (i don't know when this automatism was added).
