I wanted to share my relay control for the dust collector and the spindle.
I was originally going to go with the IOT relay that adafruit sells, but it was a little expensive and I would need two of them (because my dust collector is a hog and I don’t want it on the same circuit as the spindle/x-controller).
So I decided to build my own.
Solid state relays (x2)
50 mm fan
8 position terminal board
SPDT 3-postion rotary switch
I already had all of the lugs, wire, cable grips, and an extra outlet sitting around from various projects. I used 20 awg wire for the control signal and 14 awg wire for power.
I made the box out of 1/2" pine using the box maker app in Easel. I made cutouts for the cable grips, the control switches, the fan, outlet, and some ventilation holes.
I split the outlet by snapping the tie-in clips on the hot and neutral plates. I wired everything per my (poorly drawn) schematic below.
Hope this helps someone get automatic control without spending a ton.
I had some bad information and the control signal is not +/- 24v. The relays work just fine, but I need to put the fan on a separate circuit.
Luckily I have a bridge rectifier and some buck converters laying around. Back to work. I’ll update this post and the schematic when I’m done.
