I enjoyed your detailed RU-vid 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?
I am guessing something is wired incorrectly. The LP (low pressure line) air should only turn on when the laser is firing. The HP (high pressure line) should only open when the laser is firing AND air assist is on for the particular layer being engraved. I suggest you double check all of your wiring
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.
first off I don't see an issue using the stock air assist as the low pressure option. I will note though that typically those air pumps are loud. so going to a dual solenoid setup will make your machine more quiet when on. I am not exactly sure what you mean by if is not outputting the pressure that it is intaking. can you clarify> How did you plumb your lines? do you have a check valve on the stock line to prevent the pressurized size from backflowing? are you using a needle valve or pressure regulator? i'm guessing you are experiencing an issue potentially due to the way you have everything plumbed
i do not unfortunately. the diode goes between the two terminals on the solenoid. check the video description for information on how to install the diode
@@oeadesignworks well it was actually working but the power and trigger wires were reversed and it wasn't allowing the led to come on even though it was working. Instructions said it didn't matter but I guess it does. Swapped wires and light comes on now. Thank you
I ordered parts to do an upgrade on my Monport 80 watt CO2 engraver. I watched other videos and yours and have a question....why not just cut the wires going to your existing air pump and power the solenoid with those wires instead of running extra wire to the control board? Thats what I plan to do. My control board is different than most of the ones I see in these videos to, so I cant just use the connectors. I will mount the regulator on the wall by the laser so I can easily turn it up or down to control pressure, based on if I am cutting or engraving. Looking forward to it
I ran two solenoids as shown in the video. The wires to the existing would only be enough for one solenoid. Running new wires also allows me the ability to be able to place the solenoids where I want without having to worry about how much wire I have. Using two solenoids as shown in my video you don't have to adjust pressure for cutting or engraving once it's set up. The reason for two solenoids is to eliminate the need to constantly adjust or tune air on or off.
Awesome install video! Thank you! With the low pressure line, does it only run when there is power to the laser tube or when there is power to the Rudia?
Thank you. The low pressure line should be open/blowing only when the laser tube is powered . The high pressure line will be on only when the laser tube is firing and air assist is turned on in Lightburn
So I can have two different air pressures and so the air only comes on when the laser is actually firing. Otherwise, the air would run constantly unless I manually turn it on and off each time
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?
i don't have a kit per say. but i do have a parts list on my website. Not knowing your machine i cannot make any guarantees but i would assume it should if its similar to the omtech machines www.oeadesignworks.com/airassist
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)
glad it worked out for you. its been a while since i set this uo but i beleiev thry both close. many of the other setups that onky use one solenoid require the user to manually turn the air on and off. this setup does not require that with the 2nd solenoid. air is completely controlled thru lightburn and nothing blows when the machine is off
Thank you. If I remember correctly yes 1/4" fitting and for omtech machines at least I believe it's 24v. I have a full parts list with links to Amazon here Www.oeadesignworks.com/airassist
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.
My setup is based on two solenoids. So I wouldn't expect it to work correctly with only one solenoid. Did you turn the air assist on in the machine settings? Is it wired correctly? Plumbed correctly?

Does the RYXON support 300mA per output. 300mA for Aux Air and 300 mA for Status? Or is it 300mA for both in total? I‘m a bit confused, can I safely operate two solenoids 24v 6W without the risk to burn the RYXON controller board ?
i am not sure i completely understand the question but as you see in the video i have the two solenoids hooked up. I have not had any issues at all with mine.
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
yes, i always leave me compressor on. I have an 80 gallon compressor located in my garage that i use for other purposes as well. so i keep it on all the time. i'm curious though what kind of psi you get out of your airbrush type compressor. For cutting i generally run around 25 psi.
it may be possible but i havent looked into so i am not 100% sure. as an alternative i upgraded my led lights by cutting the wire to the stock led lights and under the gantry and tapped into thay wire instead
First off awesome video and thank you for taking the time to video this as it makes it so easy to follow along. Any tips on what to set the air pressure at? Just waiting dor the 6 pin connector to come in and I will install the kit on mone before I level it off and set it lol
glad the video helped. for the cutting layers i usually run about 35 to 30 psi. for engraving i close the needle valve then open it back up about a 1/4 to 1/2 turn. jut enough to get the air to flow thru the nozzle to keep the smoke off the lens
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 :)
the solenoid with the flow control valve should be wired to the status terminal. check out the wiring diagrams on me website. hopefully they will help too www.oeadesignworks.com/airassist
Great kit list and install instructions. All the components arrived today and I am planning to tackle the install next week! Just a heads up, the link to the 6mm flow control valves on your site actually takes you to 8mm flow control valves. Just noticed it when my materials arrived. Free returns and replacement 6mm valves set to arrive early next week. Thanks again for the great tutorial. Look forward to completing the mod on my laser!
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!
you don't want to switch the resistor for the diode. i misspoke when i called the resistor a diode. you should leave the resistor along and add the diode still. see notes in the description for which way to install.
Great video, I have an 80w coming and I’m looking through your mod videos. Can you clarify the function of the diode in the solenoid for me? To prevent power back feeding to the board? Doesn’t the solenoid already have that as part of its own electronics?
@@neilphillips9163 its purpose is to short out the back emf when the power is cut. When that happens the power stored in the coil will reverse and the diode will short it out so that control circuit is not damaged.
let me see if i have this straight... when you start lightburn to burn a file the low pressure comes on imminently ...then when lightburn get to a layer that the air assist is set to on the high pressure comes on and continues until that layer is finished then the high turns off and goes back to low pressure..when the entire burn is complete and light burn stops the file all air turns off...is that correct..? question....what do you do if you want to burn a file with no air at all..? disconnect the compressor..?
That's right. If you want no air at all you would have to disconnect, shut off the air compressor or close the needle vale and set air assist to off. I have not run into a time when I don't want any air. The low pressure helps keep the lens clean. In fact i have my needle valve almost all the way closed so almost none comes thru. No air means it very susceptible to the lens getting dirty or damaged much easier
@@oeadesignworks ...i was thinking ...put a switch on the low pressure solenoid to turn it off....there are laser paint techniques the low air pressure will interfere with. thanks
the resistor should already come installed on the solenoid. the diode is addition and should be added. check the video description for more details on how to orient for installation
is it needed to have two flows? can't you control everything with one solenoid? what is the benefit? I'm like a week away from doing all my upgrades all at once. i have the chiller upgrade, i have the exhaust fan upgrade, i have the lights upgrade, but im still researching more on the air assist. your video seems like i can save myself the hassle of adding a 2nd solenoid later on. can you explain more on benefits of low pressure and high pressure lines? based on your answer below, does lightburn automatically change from low to high power when cutting? if you are not cutting what is the benefit of have low air still coming out?
you want two flows, 1 for cutting and 1 for engraving. the higher flow on cutting helps give a cleaner cut along with other benefits. the lower flow on engraving is really just to keep the lens clean. Lightburn will switch between low and high as long as everything is set up properly and you choose air assist to be on or off in your Lightburn layer settings. I have more information on my website about what air assist does that might help clarify. www.oeadesignworks.com/airassist
@@andyvillegas487 the diode comes in a 5 pack and is llinked on my website below. The resistor is is that I incorrectly noted as a diode in the video. Www.oeadesignworks.com/airassist
The low pressure actuates when the laser is firing only. The high pressure actuates only when the laser is firing AND air assist for that layer is turn on.. If the laser is not firing there should be no air flow.
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?
@Tiffany Mosser this is on a boss laser? Did they provide the regulator/bowl? The bottom of the glass should have a small pin and spring. This allows the water to drain out once it accumulates. Unless you are pressing on it though it shouldn't blow air. It may not be seated properly and ultimately letting air out
@OEADesignWorks Yes, I have a Boss Laser. It did come with the glass bowl and pin. When I press gently pull down on the pin, it stops flowing out, but there's no pressure.
@@tiffanymosser3606 the air pressure should push that pin down from the inside. That's only for draining water. You don't want air coming out that pin all the time. Only if you push up on it and drain all the water
not sure on that one. I only have a single head machine so i don't really know how the wiring or anything works on the double head machines. although i suspect you could probably do a similar setup and just tie your final air line into you existing air lines
@@oeadesignworks think the solenoid is no good? not worried about my wiring that was triple checked. the full air kicks on i can hear that solenoid click the low side doesn't do anything. also the restrictor is fully closed and alot of air coming out i dont notice any difference with pressure while adjusting the set screw
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....
