Using the built-in Ruida “Wind” connector and a relay, I put an interupter in place for the aquarium style compressor. Ultimately, I’d like to have a compressor with tank and an on/off valve, but I can use the same mechanism when I get there.
The relay turn the power outlet to the air compressor on/off. I also used the cut-through mode on layers to give the compressor 2,000ms (2 seconds) to turn on and 250ms to turn off.
Interstingly, the test cut/engrave is much cleaner with the air off (right) than on (left) - less overspray from the smoke.
I’m looking into using dye/powder as a method of fusing color to acrylic. Normal burn with air-assist to get the pattern, then add powder, defocus, and turn air off to melt.
