This may already be addressed somewhere. If so, I apologize and please just supply a link. Otherwise, I am trying to think of a way to have the dust collection system auto start when the spindle is on. Then Auto turn off when the spindle is off.
I'd think a simple relay switch would do the trick but that is where my knowledge ends.
Any ideas... BTW my dust collection system is 120V. Thanks Chris

I opted for a foot switch instead of an auto-on function - this one works well for me:
MLCS 9089 Billy Pedal - about $40 on eBay. (Step on the pedal once for on and once for off, they also sell the same pedal as a 'deadman', i.e., you have to keep your foot pressing on it for it to power your vacuum).
Not particularly heavy duty, but I've been running it for over a year with no problems.

It's a little convoluted, but you COULD mount a normally closed limit switch on your Z axis so that once the Z axis goes down so far (to start routing), it is off the switch, and energizes a relay to turn on your dust collector. Depending on the amp draw of the dust collector, you may be able to get away with just using the limit switch.

I would be really surprised if there isn't an "enabled" signal that is accessible from of the VFD that powers the spindle. At the very least, it would be possible to piggyback off the signal from the processor that tells the VFD to run. This is something I'll be working on in the next couple of weeks as I extend my dust collection system to the router. I'll post details when I get to that point.

I use a small remote clipped to my belt loop to activate my dust collector. That way I can use it for other machines. I usually keep it on a hook at the entrance to my workshop, same as hearing and breathing protection. That way I'm geared by habit to grab them for my woodworking sessions. Yes, I do wear the breathing protection even with dust collection units on.

So the reasoning behind the spindle on/off activation is so when I leave the machine alone. When the routine finally ends the dust collector doesn't keep going until I figure it out. It's sort of a dual purpose. Not excessively running the 1.5 HP dust collector unnecessarily and an indicator that the routine has ended. The spindle is a;ll but silent compared to the dust collector. Before anybody gets overly concerned about me leaving the machine alone I start to gain trust after the fist couple are good. Hmm that another thread....

Trying to get in touch with full member Train Driver who I saw in another post lives in Augusta. I live about an hour west of there on I-20 and would like to see his machine and learn a few tips and tricks before I actually make the plunge to order mine.

Hmm that another thread.... I haven't yet gotten into this on my machine yet but it's coming. I did, however, have a consideration to consider. The coolant pump cycles on and off with the spindle enable and it's powered from a small typical wall outlet power supply (presumably from 220V AC). You could rig up a relay off that 220V power to the 12V power supply or off the 12V power itself that cycles the coolant pump. That's how I plan to make mine work...but in natural fashion for me, it will be a little more complex ;-). I'm hacking a relatively low cost remote control setup (Amazon) with a small arduino processor that will mount inside the enclosure to monitor that 12V signal and send the RF signal to the dust collector receiver to turn the dust collector on/off. That gives me the flexibility to move the machine without fret for the signal wiring.

Ahhh. Yes. I like the idea of my relay working off the 12V Pump. Great idea!! Please keep me posted if you beat me to it. Thanks! Chris

Nice job. With the Arduino you can add colored flashing lights....
