Dear All.
I add Solid State Relay to control the Spindle recently.Relay is working well with board (Probotix). But,when i using the Touch plate /probing function,spindle turn on when cutting bit touch to the plate(sensor). Anyway to solve it?

Oooh! That's not good! Sure won't do your touchplate any good! That's got to be a wiring or grounding problem. Not likely anyone here can do much to help find it. You need to very carefully double-check your wiring and grounding. It is especially important that all grounds tie back to a single point. Never daisy-chain grounds! Put a voltmeter on the control input of the SSR, and see what it does when you ground the touchplate. It should be at 0V and stay there, but I think you'll see it is jumping up.

Check that you do not have the same pin set for the probe as you have for the spindle.

That may be stupid and simple check if you have short in your ribbon cable and change it.
I did have similar issue at some point as I was changing stuff on my machine.

thanks to all. Will checking the wiring again.

I use smooth stepper setup and 2 BOBs by Campell design where my bobs are connected to smooth stepper board by ribbon cables and that is where I had issue.
If you still have problem explain your set up.

Is BOB problem. When i took off the wiring,only connect with PC and power supply. The Probe Led in Mach is blinking.... :-\
