As of version 1.90.060, Art added a new G-code that may work for you. Here's his explanation:

OK, A mixed bag of tricks today.. a new toy in the Gcode, and new PlugIn
stuff..


1)

First, lets talk about the new Gcode command before letting the non G100 people
tune out.
(This one'll get me in trouble for being non-standard Gcode. :-) )
This command is for Plasma OEM's, but Ive released it in the general program
just in case
glue appliers and such need it. It is the "ExternalControl" Gcode command
specified as

"EePp"

This command must be on a line of its own. Its purpose is one not found in
other CNC programs, but handy
for those that need it. It will turn on or turn off an output without stopping
movement. In other words, consider
the following CV moves..

G1X10
G1X20
G1X30
G1X40

These 4 moves will run without stopping from X0 to X40. If we wish to turn on
a glue application gun, (or turn off THC AntiDive ) between X10 and X20 we can
now do the following..

G1X10
E1P1
G1X20
E1P0
G1X30
G1X40

The parameters of the EePp call are Ee where "e" is the output signal..ex E1
measn OUTPUT1
The Pp paramater is state.. ex. E1P1 = (Turn on OUTPUT1).. E1P0 -- Turn off
OUTPUT1

Any of the 20 OUTPUT signals may be used. They may be turned on or off during
movement in that way.
I dont know of any similar fucntion in Gcode, all CNC machines stop to set ins
or outs, sothis one is new and for specific purposes where a person wants to
trigger action at a certain spot, but doesnt want to stop to do so..
It was invented for a Plasma OEM who wanted to turn off anti-dive before the
leadout move, but it has application for solder flux application, or glue
applciation, painting , and so on.. A paint gun could trigger any of 20 nozzles
for example.. It is IMPORTANT that this command be on its own line. This is
because the "E" command, is also a number specifier ex. 1E-6 so a G1Y1E1P1 woudl
not be seen as syntactically correct.

Anyway, its there if one has the requirement..

thanks, but how do i trigger an output while the dwell is active? I'm using sheetcam to convert the Dxf to Gcode and there is a function Preheat that triggers the dwell command before starting to cut but i don't know how to use it as an output. Any ideas?
