Wireless remote dust collection override with bitrunner

[nateo (Nathan)]

I have my dust collection tied into my bitrunner so it turns on when the bitrunner turns on and was looking for a way to have a remote override. I found these parts and had it working without having to touch mains 120V.

I just added a 120v splitter that normally goes to the router, added a 5vdc power supply that i had laying around.

I used a AC/DC outlet that has a signal input:

along with a wireless relay as well:

and added a 12vdc power supply to the always on outlet of the strip to power the remote relay.

This way I can take 120VAC from the main power supply and not run the dust collection through the bitsetter. Overall this is very handy and is working out very well.

See picture for wiring, note I am not an electrician and you should only do this at your own risk.

I checked one of those units out, but didn’t want to have so many individual boxes with cables running all over the place.

I had already put together a dedicated project box with an E-stop, manual switch & power monitor in it.

So I decided to enhance it further with the addition of an adjustable current switch, power relay, auto/off switch.

The current switch(orange arrow) is adjusted to turn on when it detects the increased current of the router(when the BitRunner turns it on), but stays off when it’s just the Shapeoko/LED lighting using power. Then via the power relay(yellow arrow) turns on my speed-controlled shopvac.

I have found that by keeping my dust collection hoses as short as possible, eliminating the cartridge filter from my shopvac(still has a re-usable bag inside) & venting to the outside, I can still get adequate dust collection air flow when I throttle the vac back to 500W vs the 1200W it pulls when running full out. This is a huge difference in power usage for long-duration 3D carves. Also keeps the overall circuit utilization well within the limits of a 15A breaker & reduces the shopvac noise level.
