As you may be aware, Langmuir plasma tables use CrossFire proprietary controller and PC machine interface software. My understanding is that the controller gcode dialect is a superset of grbl v1.1e (GRBL-M3 in LB), specifically in cases of M and/or G words for THC and IHS control. It may be that LB’s device gcdoe blocks/templates for ‘Tool ON’ and ‘Tool OFF’ will suffice for the scope of their use once per cut. However there are some toolpath conditions (sharp corners and circles specifically) where using THC and feerdate words will improve cut quality, and I don’t believe LB device profile will have that interface.
