I have an IOT relay wired to the PWM on my Shapeoko board to turn on/off my router and vacuum. I recently added a JTech laser using the header install from their Shapeoko kit. Now when I turn on a toolpath to use the CNC both the router/vacuum and laser come on regardless what the $32 GRBL setting is set at.
Is there a way to selectively turn off the IOT PWM versus the Laser header. I am assuming not since I think they are both PWM connectors but hate to assume.
