I haven't looked but I am fairly sure the the software supports mcode with decimal places ? M7.0 or m7.1 etc and so on.
the current coolant/cutting fluid controls are way to limited and require to much special handling. It would make sense to update the current scheme with mcode that could be numbers
M7.1 air blast
M7.2 mist
M7.3 flood
M7.4 through tool
etc and so forth. I can modify the existing post processor but where exactly would this change have to be made in the core of the linuxcnc software base ? Also the existing mcodes for coolant can be left standing. I am just trying to avoid creating custom mcodes for controlling the various cooling systems I am adding to my machines, but many NEWER cnc machines also have many varying types of coolant schemes.

Minor suggestion - leave the mist as M7, and flood as M8 and save the 'derivative' M-codes as M7.n or M8.n
M8 - main flood
M8.1 - supplemental
M8.2 - TSC
M8.3 - washdown
M7 - main mist
M7.1 - supplemental
Etc.
M8 - main flood
M8.1 - supplemental
M8.2 - TSC
M8.3 - washdown
M7 - main mist
M7.1 - supplemental
Etc.

As far as I'm aware Mcode numbers must be integers (Gcodes can have decimals)
You could create a single custom mcode with a P word though.

Ok, so configure coolant m codes as follows
M7 p1 mist
M7 p2 derivative
M8 p1 flood
M8 p2 through tool
M8 P3 high pressure through tool
M9 p01 mist off
M9 p100 all off
As kind of a loose structure?
Thanks for the reply. If anyone knows where in the code base to look for this stuff it'd be nice to save me the time of having to dig through tons of folders and files

I was actually picturing a remapped (ie currently unused Mcode). This would be a rather simple gcode remap where you could then use 'motion.digital-out' pins for the appropriate coolant flow.
Actually adding this to the source code will likely involve
a) a number of files in '/src/emc/rs274ngc'
b) pose the additional challenge of there not being a suitable NML command for all the different coolant variants you have in mind.

This is what I did for my non-standard cooling stuff. Just cooked up some Mnn.ngc files to take care of stuff like spindle taper air blast, washdown, and multi-mist nozzles on my gang lathe.I was actually picturing a remapped (ie currently unused Mcode).

are you at liberty to share those mappings ?

The issue at hand, the lack of NML commands is a problem that requires a lot of extra effort for every retrofit that could be solve once and be done with.I was actually picturing a remapped (ie currently unused Mcode).

M210 to M213 are my extra mist valves. Subroutines look like this:
The other ones are main and sub drawbars, and 268/269 are G10 front/back tool rotations (hoping to incorporate that in post processor so the display automatically flips to the right orientation).
I could have mapped them to a more logical M-code number... Maybe I'll see if m207.1.ngc & m207.2.ngc work and not cause LCNC to vomit.

They're just basic xxx.ngc subroutine files, specified in the INI file. Not an actual remap of an existing M-code with new behavior and -P/-Q passthrough params.
are you at liberty to share those mappings ?
