Air Assist control on Omtech K40+

Starting my laser journey on a new Omtech K40+ (upgraded version from Omtech) and trying to set up air assist control. I need some insight on how to do that within the GRBL version of Lightburn.
The Omtech upgrade card is apparently not compatible with this latest K40.
Any help is appreciated.

There is little data on these OMTech or Monport upgrade cards. There is nothing I’ve seen to support any kind of air assist using them.

Other boards, such as the DLC32 types, have codes/pins to support this, but not these…

How about a manual switch on the console?

Yes, little information is correct. Even from tech support, there is little information.
