or2 example correct ? need to flip on VFD with coolant requests

So you'll be fine until you add your through tool coolant now
Then you might need an or3 which does not exist
You could daisy chain things in hal or you could use that as a really simple example to write your own custom component based on or2.comp
Its so simple or2 is achieved with one line of code...
Source is in github github.com/LinuxCNC/linuxcnc/blob/master.../components/or2.comp
Use of halcompile is well documented linuxcnc.org/docs/2.9/html/hal/comp.html
Any custom components are treated as if they are core code once built and installed which is very cool.

next up is learning how to add gcode the to IOcontroller, the whole remap m6 call toolchanger thing, really irks me.

I started dusting off my programming concepts books, haven't cracked them since my freshman yr of highschool.
