CORRECTED gcode…
Since you don’t have a THC nor a Z axis, all you’re going to need in the Tool On device action is:
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;tool on
;|ABS| (macro wasn’t available in last beta I used)
;adjust this code for G91 or G90 mode
G0 Z3.7 (move to pierce height)
M3 S1000 (fire torch either via Spindle Enable or SPWM)
G4 P0.800 (hard coded, dwell var not available here)
G1 Z1.5 F1000 (move to cut height)
G1 F{speed}
;|RESTORE| (same as ABS I presume)
;end tool on
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
In LB, use menu Edit->Device Settings, Custom GCode tab
to edit the device actions. See the doc for more details and edit macros and choices.
