I have a monport 80W laser and used most of this video for my air assist upgrade. Great Video btw. I only ran one solenoid my set up because I tied it into my existing air assist. My thought behind this is the existing air assist can give me the low pressure air and the compressor can give me the high pressure air. When the solenoid is activated by the machine, it is not outputting the pressure that it is intaking. It only increases the pressure slightly. Any thoughts? I only used light burn to program the settings. I have it wired to my "wind" terminal.

Great video How do you remove the air from the system? When installing the hoses there might be air

Why did you use 2 solenoids?

Thank you very clear, question other than the chiller being powered on. The laser machine is off the whole time correct?

What size tubing do I get?

Make sure you distilled water not any other bottle water. Also recommend adding some anti algae to the water.

Hi a very good explanation. I recently got a cw5200 and having some temp issues. Does the length of the water lines affect the cooling ?

I enjoyed your detailed UA-cam video, and I think we have identical machines, including Kt322N controller I'm having a problem. I wired the LP solenoid to the status terminal and air flows as soon as the machine is turned on. The HP solenoid works fine When I'm running a job with the Lightburn air assist turned on, both solenoids are on. I assumed that the output terminals would be live only when the laser is on. I'm finding that this is the case only with the HP solenoid wired to the air terminal Any suggestions?

Great video. But, I can't stop thinking that you sound like Kurt Russle. I like the mentality of, "Let's rig this up and see how it works first."

How do I wire it ?????

Great instructions. Easy to follow.

A lot of relays do not have an internal "protection" diode" that prevents a back EMF - kickback voltage from the coil when the magnetic field collapses after turning off. These voltages can measure in the hundreds of volts and with using a ONE DOLLAR DIODE - typically a 1N4007, (700 PIV @ 1 amp), you can help prevent the damage that can occur to the device that controls the relay. Install the diode across the relay's coil's wires with the Cathode -banded end - to the positive coil wire and the Anode - looks like letter "A" viewed right side up to the relay negative wire. When the coils is turned off, the diode shunts-shorts the coil's kickback voltage from flowing back into the control circuit. This is how I wired my relay to control an external AC powered air assist for my laser. The laser outputs 24 volts DC to power the stock air assist so I used a 24 volt, (coil rating), DC relay to control a 120 volt AC air pump. SO, don't take my word for it, look it up and discover that this is a way to protect sensitive electronics from damage due to a relay's kickback - back EMF - voltage that is very easily preventable....

Hey man, sign shop owner here and I just bought a omtech pro and would love to call you for some pointers getting it set up

Why didn’t your laser home when you turned it on? And how did you setup your smart plug to turn on the laser and chiller? Thanks Tim

What size are the barbs on the back of the chiller?

Its possible to mady dry test of Air assist connection? I making DIY laser and now have made electric box with drivers. But don't have connected axis and laser power supply. Try use pulse signal but it not turn on relay.

Did this, can get the computer to move the laser but can’t get a file transferred. Using a Mac book over WiFi. Any suggestions?

Hey there thanks for putting this video together. I am finally looking at upgrading my air on my 60 w big blue Chinese laser. Would your kit that's available compatible with that?

The uk code doesn't work for me, is it expired?

Thanks for the vid! I couldn't make sense of the instructions that came with the chiller. Really appreciate you showing how to enter settings on the machine.

Just tried the air assist setup with one solenoid, will not work correctly. I have one on my other laser, not an Omtech but hooked up the same way, works. I have both wind connection and status like yours, tried both ways non working. Anything you can Think of that would help.Thank You.

Thank you 🎉

Exactly what i was looking for. Just got my AF2028-80 today, and will be getting it setup this weekend. Thank you!

Is the 2 solenoid approach used because you have an always on air compressor? I have a dedicated airbrush type compressor for mine and only use one relay for dual air control. If it helps others in this case you can use the status line to power up the compressor and have that coupled with a single solenoid setup on a Y with the second part of the Y flow straight through to a reducer. In this case the laser fires up and status turns on the compressor and if the layer has air assist off it just flows through the branch of the Y with the restrictor, when air assist is turned on that enables the single solenoid on the other leg of the Y so you get high pressure flow. When status goes off - the SSR shuts down the compressor Or short version - instead of 2 solenoids and an always on air supply, you can also have the air supply on a relay/SSR and then control low vs high air supply with a single solenoid

I don't see blow type in the options in RdWorks. Under the other section its just not there. Do I need to update my Ruida Controller firmware? I have a Ruda 644XG Red 80W with RDLC -V8.00.67.

dose the neutral connect to the ground as there is only two terminal on the solenoid. the video leaves this out and wanted to double check

Is your laser on during the reset process?

After a few months of searching i was finally able to find your video that shows me everything that i needed to make my own automatic air assist. I've had pumps before but using relays to power them on or off automatically sometimes causes power spikes in the line making the machines reboot (prob poor grounding on chineses air pumps). with your video im able to do my own setup with my compressor and even modify it to be able to run 2 machines at the same time from the same compressor and keeping the automatic function working! thank you! Just one question do both solenoids close as soon as the power is off on the machine or they keep the previous state? Asking this because if they stay on the current state and you need to close the air from the compressor yourself then its not need 2 Solenoids, you just had to use 1 to allow high pressure to pass (Air Assist ON) and the flow control on the second line to be gentle air (Air Assist OFF)

my button said RST, not RET. this caused me alot of problems. the manual I received was also wrong. hit RET to save the settings I just changed.

I have the CW 5200 chiller. Would food coloring in the water be detrimental to the system? It would make seeing the water level much easer.

Great video, thank you so much. A few questions...1/4 fittings and 12 or 24v on solenoid?

I went through the video for the air filter/water separator and I am still not getting any pressure. It's just blowing out of the bottom. Do you have any suggestions?

HI AS I LIVE IN HOT COUNTRY LIKE IN PH IVE EXPERINCE SOME WATER CONDENSER ON TUBE AND HOSES WHAT IS THE RECOMENDED SETTING FOR 35 DEGREES CELCIOS.

I have a question for you i have the same laser you have here.. how do i get my control panel Arrow keys to move around 🤔 also my bed to move up n down. I set something up wrong n my control panel..

Excelente, gracias 🙏

Thanks, it was super helpful, I was able to set up my Vevor DZ5200LS-QX chiller with these exact same instructions.

I can't get the template for the focus tool to download is there another way

Omg you lost me setting it up after good down the right arrow and the set button

my low pressure isnt coming on is the something i need to set in the settings

Do you have a picture you could post of the diode installed. Does it go where the wires go into the block 24 volt and wind?

Is it possible to leave the wiring on the old air assist pump and run to led strips inside the unit for extra light?

Do you have to put the resistor in or is that optional?

Hello. I could use some help in troubleshooting my issue after trying to do this upgrade. I am not sure what to do at this point. Not sure if I possibly damaged the control board that I can't get air assist to work properly, or if there is a wrong setting. At this point air assist work whether I have it selected or not, and it will not power the low pressure solenoid. The "Status" pin seems to fire the high pressure on, but the Aux Air pin doesn't seem to actuate the solenoid.

Did you use distilled water? Anyone know if that helps keep the water/system stay clean longer?

Do you have the diode video?

did you ever switch the resistor for the diode? is that actually needed to be done? just ordered everything but wanting to make sure i should install the diode. thanks for the great video!

Since 24 volt is a simple circuit, "Ground" is like the "Neutral"...the return path completing the circuit.

Great video!! It has helped so much. I just have one question because I'm a visual learner and with all the reds I am confused... I have my blue electrical wire in the one with the flow control valve, which spot (status or wind) does the blue wire go ? I used red , green , and then blue and white. Thank you :)

Do you connect rotary to X axis driver?
