Laser will only fire with CNC turned off!

Don’t follow you here. It looks like you have wp (water protect) wired to the L-AN1… ?

What kind of sensor do you have for wp?


Most of us wire LPWM1 to the IN. L-AN1 is the analog output of the Ruida.


Why do you have two wires going to L-AN1? What is this wire bundle, water protect?

Why is the red wire going to L-AN1?


Does this thing actually ‘home’ properly when booted?

Do you have ‘Crash’ switches on your machine outside of the normal ‘working area’ limit switches?

That is the only case I know of to use the Lmt*+ connections.

My suspicions are that you have it miswired, at least with L-AN1. If there is not a specific reason, I’d move that to LPWM1 on the controller. The red wire that I pointed out in the ‘bundle’ is questionable.

The type of water protection sensor only needs a pair of wires. Yours has three… a pwm sensor like this isn’t compatible with the Ruida input. It’s looking for a path to ground indicating it’s ‘active’

Good luck
