AlanDavis and PikeLake had the outstanding intro and feedback on the box. The relay controls the router power on/off essentially. I set the speed on the router. I have not tried to determine if I could control the speed with the box at all. In my case, I have the yellow and black cords running to both the power relay and the gshield pins. Essentially copying this photo:

This is awesome! I do have a question though. I am using a TB6560 control board and will be using Mach 3 with a DWP611ā¦ will this product work for me given my setup? Thank you

I bought this relay in anticipation of my X-Carve. I finally did my machine setup yesterday and this worked beautifully. Thanks for this!

@WilliamJames Iām not sure. Iām using Easel straight up on a Mac. Plug and play 
@pike_lake Cheers

@pike_lake - have you used this relay to power on your spindle via UGC? Mine powers on if I flip the spindle switch on the power supply to the on position, but in the logic position, my 611 doesnāt power up - Iāve got it wired just like in your first picture. (for some reason I canāt connect to my machine via Easel - Inventables Tech Support couldnāt figure out why though)
To turn mine on I have to send an M04 command and for off an M03.
Little odd, but it works.
@ErikJenkins Iām REALLY new to this (like, tech support got me rolling this morning). I assume the M04 and M03 get edited into the gcode before itās brought into UGC? I tried that and it doesnāt turn my 611 on.
try to type in the commands in UGS and see what happens.
make sure it works for you before adding it into a gcode file
try to turn it on with an M03 command
I tried the M03 command in UGS - it returns with OK, but the 611 doesnāt start up.
Try M04, mine doesnāt start with M03 either
Stupid fat thumbā¦I meant M04 doesnāt start it (but neither does M03, for that matter)
Check your wiring, make sure the switch is on logicā¦
Also verify that you are using the correct pin on the arduino.
Which pin on the arduino? That could explain a few thingsā¦ I went just like in the top pic in this thread. S+ and S- on power interface to the +/- on the relay, the spindle switch on the power interface was set to logic (even though itās set to off in this photo), and the 611 was powered on, plugged into one of the normally off outlets, and the power switch on the relay was on.
Do I need to change up how itās wired?

I canāt tell in that photo where the black and yellow wire are attached on the arduinoā¦
From the left, pins 4 (yellow) & 7 (black)
So is that pin 11 and Ground?
yup
