Hey folks, not sure if this is the right place to look for help but...

i ran across this video on Youtube...
https://www.youtube.com/watch?v=Vbk6...MdK9mk7pVRwYO6

and liked how he has his air blast/mist coolant "pulsing" on and off and was wondering if this is doable in Mach3.

I have an oldie DIY unit running off a g540 and using Fusion 360.

some guidance would be greatful.

thanks in advance,

Al

oh, when i asked Youtuber, his reply is as follows:

add to main.HAL file
#**********************

# generator for ALCOHOL
#**********************
addf comp.1 slow
addf siggen.1.update slow
addf constant.1 slow
addf oneshot.2 servo-thread
addf timedelay.1 servo-thread
addf and2.3 servo-thread
setp constant.1.value 0
setp siggen.1.frequency 1
setp oneshot.2.width 0.5
net s2 siggen.1.sine => comp.1.in1
net n2 constant.1.out => comp.1.in0
net a2 comp.1.out => and2.3.in0
net alcocycle1 => and2.3.in1 #checkbutton input
net alcocycle2 and2.3.out => oneshot.2.in

#**********************
# ALCOHOL CONSTANT-overrides generator for alcohol
#**********************
addf or2.1 servo-thread
net alcoconstant => or2.1.in0 #checkbutton alcoconstant input
net alcy oneshot.2.out => or2.1.in1 #alcocycle output
net alcoout or2.1.out => hm2_7i76e.0.7i76.0.0.output-11(depends about interface)

and yea, i'm still scratching my head.

He gave you information for linuxcnc not mach3/4. You could setup a macro that pulses an output in Mach software

Hi,
It should be quite straightforward to implement. The way to do it in Mach3 is to use the Macropump feature, or use the Brains function.
If I recall correctly the Mach forum has a section there for Brains. If you ask the question there you should get your answer.
Cheers
Peter
