Does anyone have a better copy of the "CNC Router Controller" document here on post #16? I can't read half of whats on there. It looks like what I need to understand and finish my setup!

Thanks in...

Does anyone know if there is info out there to do the "Big Tex" touch off method for UCCNC?

Kinda like groping in the dark, how do you know what to ask, if your trying to learn. lol

Could I wire in a 12v power supply to a power distribution block and run both the UC400ETH and the Relay also? Good practice or method, or not?

Is there any other advice that I might not foresee...

So this brings up another question. My UC400ETH Ethernet CNC...

I don't know all these things you already know. So I have no clue, that's why I ask.

I am hoping to grow in this knowledge.

When you say, " it might be cleaner to find a relay with a 12V coil...

Okay, I think I see now.

The blue wire marked VCC is the same as the Yellow block top left marked 5v VCC.

And the IN3 marked blue wire is the same as the Yellow block pin marked IN3, right?

I am sorry, I guess I am either too dumb or you are assuming I know more.

The 5v on the VCC top left, where is that coming from? A 5v power supply I am providing?

That yellow block it's going...

I know you are trying to help me, but are you saying the relay I have will do what you have in that diagram?

116 people have viewed, not one response. You responded, but only to inform me of my lack of info, yet you hit the nail on the head in your response... "E.g. How exactly do I wire a 12v water pump to...

Yup......

Gotta love community....

I have a router table I am trying to complete, and I am new to this field.

I have the 4'x8' Gryphon CNC with the MX4660, 2.2kw water cooled spindle, SainSmart 4 channel relay module, UC400ETH...
