Here's the generic RuiDa wiring diagram that came with my laser:

Thanks for posting that schematic.

My cheapass red & black didn't come with an air solenoid, so the RDworks question "If Blowing: (yes/no)" is meaningless and I have to turn the blowing on and off myself.

I had a look at the controller and saw the pin marked "wind" and wondered if that might be the output for a solenoid but hadn't poked it with a meter yet to verify.
The schematic shows that "wind" is indeed the drive pin for the air solenoid so I just need to get an appropriate solenoid and do a little plumbing.

I don't suppose anyone has a source and/or part number for the connectors that fit the controller?

Cloudray sells a complete kit. I think it is in collaboration with Russ. Russ has produced a video on his experiments and installs.

see pg 26 - note power ratings

Some more data - I do not recommend powering a solenoid via the controller - I recommend using a relay like this- using the controller to operate the relay which in turn will complete the circuit to power the solenoid using a 24v DC external power supply

However Russ and other have engineered configurations shown below This spread sheet may be of use ordering some stuff.

Thanks Doug & Pete for the info!

The Cloudray kit is a temptation for $60, but all I really need is the air solenoid and a connector that fits the controller. I think I have all the other hardware lounging around here (somewhere).

Extra credit thanks to Pete for the controller manual pdf. I hadn't seen that yet.
Since I had no idea how much current the controller output could sink I figured on using a P-channel MOSFET to drive the solenoid. I've got oodles of electronics parts around here.

EDIT:
The connector for the controller appears to be 0.040" square pins on 0.200" centers and I found a connector that has 0.100" c/c pins from a... something... that fits fine and I can make work.(Yeah, I'm a bit of a pack rat)
So now all I need is a 24vdc solenoid and I'm in business.

Hi Jeff. Simple question for someone not into electronics. I note there is no Z motor functionality shown on your diagram that connects to the LCD?

Hi Brian- I have been looking at that schematic for 3+ years and never noticed the Z wiring was missing. But yes the Z axis is wired to the controller exactly like the X & Y and controlled by the controllers front panel. Some machines have AC motors and separate up and down switches for the Z and then there is no Z stepper or stepper driver.

Neither is Y. The other axes are omitted for clarity. They are wired in the exact same way as the X axis (which is shown).

Personally I took the old fashioned way out.

My exhaust blower that came with the machine is NOISY! even on the other side of the wall. And it so happens my Red and Black China machine had an unused switch on the front panel.

Now of course it couldn't be that easy, the switch in place was way below the required amperage to switch the blower on and off. Time to start scrounging!

Well the switch was the easy part it turns out. Snagged a switch from an old power strip. In the US they are also breakers, an added advantage. A little time with my nibblers and the small square hole is now a somewhat larger square hole. A piece of an old extension cord ran down to the back convenience outlets, and my top outlet is now controlled by a 15A switch / breaker on the front of the machine.

Part of my reason for switching the exhaust and air assist is that with all my research I managed to get a unit with a top wisdom controller, and the AutoLaser software does not like loosing the link to the cutter. That and it's not sucking all my heat / AC out of my shop just sitting there waiting on me.
