That is a cool gadget for the price and would probably work well for on off control of all the equipment you mentioned. In assuming you’ll hardwire the E-stop but how would you implement the spindle and vac on/off, with an M42 code?

I use an SSR on my homemade arduino reflow oven and i think it only cost a few dollars but I doubt it could switch fast enough for pwm. I think the on/off control is a good idea but i find that i only set speed when i start a job or after a tool change so not sure I’d make much use of pwm spindle speed control.
