This is similar to my setup, but not wireless. I run a combination of the Iot Relay plugged in to the iVac switch. When the iVac switch senses the current draw from the router it turns on the ShopVac. This also enables you to turn the ShopVac on and off as needed. For times when I’m also running air I have an electric solenoid valve, which I also power with the Iot Relay, to shut off the air supply once everything is done.
I tried that but the spindle just stays on, I am one if I got a bad ardurino. I can control it with the toggle on the power box.
any update on this…is it necessary to buy that relay…or you can do something in the coding without buying the relay…if so pleas post detailed instructions…my x-carve is coming within this month…and it will come with the 240v dw611 spindel…forgot the exact model…
@Kasba Show a pic of how you are wiring it to the x-carve.
@BryanJosue Yes, you need a relay of some kind. The easiest option is to find something ready to play similar to the following, but in your case you would need to find a 240v version.

Ok so sorry if this is a dumb question or has been covered but i have read this whole thread and many like it. My question: if i buy the relay linked to from amizon. This will enable the G-code to control the spindle as in on/off and any rpm (or even a min of 12000 or whatever was discussed to enable the relay).through some sort of g code commands?
I am familiar with editing g code and have no issue if i have to manually edit the code.
I am not familiar with firm ware and scares me to mess with what is put on the ardino but if i have to i will figure this out.
So long question short is what i described even possible? I have been reading that rpm control can only be achived with the $155 pdi or whatever and that may only work by manual dial and not through g - code.
Guess i am getting lost in the complication of this. I just want the dewalt 611 to be controlled through g code comands including setting and changing rpm. So maybe someone could make a video of how to do this or break it down in simple step by step how to.
A relay does not allow control of RPM on the Dewalt. Can only turn on and off from the Gcode.
Thank you for the quick response. I guess on/off automation is a good start as i wont have to baby sit the machine as much. I guess i will see how it goes with just setting the dewalt spindle speed on its own dial. My concern is dialing in proper feeds and speeds and having the ability to program specific rpms would be awsome. To me. But maybe im being too fussy and might not even be an issue. I pick up my machine in 3 weeks and cant wait to get started. Thanks again. It helped me alot.
Hopefully this thread hasn’t gone too stale. I purchased the relay and have it wired up the exact way you see in the photos of this thread. However unlike some of you who had the probably of getting the switch in the relay to actuate I’m having the opposite, I can’t turn it off. I have the PWM and GND wired to the correct pins and the wiring from the PSU to the relay are also wired to their respective postions. My router is plugged into the “Normally Off” outlet and the second I turn the Arduino on the switch triggers. I can’t turn the relay off with the toggle switch either. The only way to kill power to the relay is pull the wires from the PSU. Is the arduino bad? could my wiring be bad? Really at a loss here and was looking forward to running it off the relay.
Is your power switch on the power supply set to logic?
Hi Erik,
Yes it is, but even when I switch it to off the relay stays on.
Is it wired just like this post describes?
Yes, just like the post and the previous photos at the top of this thread
Have to buy a new multi-meter today, will check the voltages tonight. With everything wired the switch is active and the green LED is lit. If I remove the red and black wires from the relay via the green wire clip the power is cut, LED turns off, and the Normally On outlets get power so it seems to me that the relay is functioning properly.
I got the same one it works perfect 
I use the command M3 to start spindle and M5 to stop spindle and it works fine…
Hi Phil,
Tested the voltage and they are as follows:
23.5V - Off
24.4 - On
22.4 - Logic
Fingers crossed you can make heads or tails of this
Rewired and soldered the pins to the arduino. Ran new wires from the header pins to the logic switch, only the two yellow(4th pin) and black(7th pin) wires are attached so no limit switch wires are in the way. Fired it up and am still getting the same readings… Is there any way to see a diagnostic of what the arduino is outputting to the different pins?
Do this test.
- Unplug the connector that is on the gShield for the homing switches and PWM signal.
- Place the spindle toggle switch in the off position.
- Place the power supply switch in the on position.
- measure the voltage on the right two positions of the four position plug in connector to the power supply module. Should be approximately 24 VDC.
- measure the voltage on the left two positions of the four position plug in connector to the power supply. It should be approximately 0 VDC (you could have a small voltage reading), not 24 VDC.
If the measurement in step four (4) is 24 VDC and the measurement in step five (5) is 24 VDC then you have a bad Inventables circuit board (the part that has the spindle toggle switch and the plug in connectors to the power supply).

@LarryM both sets gave me an out put of 24.4V. So I guess I need to contact inventables and ask for a new circuit board for the PSU?
