IOT Relay wire up with 7W JEtch Laser

I am currently using a IOT relay to control my dust collector and spindle. The PWR control for the relay uses the same ground location that my JTech Laser says to use. Can I put both grounds in the same connector or will that cause an issue?


Yes. All the grounds on the board are connected.

i have the relay setup with spindle and dust collection. I have the laser but was never able to connect this to the relay also…
Do you have all three items working auto through the relay?
Dust, spindle & laser? if so can you share the wiring please?
