This was exceptional help in getting my system quickly adapted! Thanks Matt!
No Prob - Cheers
I didn't expect such a thorough video from Korg. Thanks a lot! Going to be doing this to mine tomorrow when it arrives.
hope your install went well - cheers Matt
Following this video I was able to install it in my Ruida 6442s - thanks so much!
You're welcome! Cheers Matt
Nice touch to add the extractor to the relay, clever.
Thanks 👍
RUclipsr of the year! I love the time marks in the description, so so helpful. I'm surprised that kit doesn't come with a small piece of DIN rail to help mounting.
Thank you, Yes it would be nice to have some mounting options included in the kit.
Thx for the great tutorial! I upgraded my air assist because this video!!
Nice add on, thanks for sharing!
Thanks for the comment Jeroen, It is a great addition to the machine and it is working well. Cheers Matt
Works perfectly, thanks. I did not use the relay, but am considering it to control the exhaust fan, but from a spare switch on the front of the laser.
May add the air compressor and cooler in the same manner just via front panel switches as well. I'll replace the external power outlets with proper 240V 3 pin Australian ones in the process, and will likely add compressor/cooler/fan power via a separate inlet at the rear rather than the main power to the laser
good idea, not wise to have a compressor on the machines power outlet circuits, run separately
great video I was thinking i need this, now i know how to do it. Thx
Thanks for your comment Wayne. It was pretty easy to install. My goal with this video was too demonstrate installation in an easy to follow manner. I hope it helps 😊. Cheers Matt
Great video Matt!! Thank you so much for this tutorial. I love my new ultimate air assist!
Good choice!
It's funny that you also have the chiller on the right side. I bought an 80W Omtech laser a few months ago. And I bought the exact same air assist that you have. The only difference is that there is a little air pump on the Omtech laser and I want to connect my compressor with it.
Just ordered this kit for my laser. Looking forward to getting installed. Mine will be a little different as I have an 80 gallon compressor I use in my shop.
Cool. I plan a video for additional solenoid to shut off air for air compressor so it does not deplete the air in tank when not in use. Cheers Matt
@@MWLaser That's great, I hope that one comes along very soon! Thanks for your videos, they are very easy to follow and understand.
This add-on works beautifully. I've spent a couple of days trying to wire up a "Delay Off" relay with no success. It would be very useful to keep the exhaust going for 5-10 seconds to clear the enclosure. Would you consider coming up with a wiring diagram for this and a link to the proper Delay Off hardware?
The 100uf capacitor can be increased to 220uf for ~20 second delay.
Very good video, very in-depth on how to install. Shane these aren't factory fitted. I'm finding that when I'm engraving with air that the engraving has a white residue that is hard to remove. Without air it's perfect.
Glad it helped
Thanks for this video as i have just ordered my self this item but sadly i cant find the manual which you said was on the net do you by any chance have a link to it many thanks
FANTASTIQUE
Sorry I didn't see this comment earlier - Thank you. I'm glad you found the video helpful. Cheers Matt
@@MWLaser thank you mat
Great! How to work double head?
Hey Matt, great videos. It’s hard to find much about installing this other than this and Russ’s video. I was wondering, on the over ride switch. Is the ground wire soldered to the middle two pins or the end two?
The ground gets wired across the middle two pins on the switch.
Thanks for the feedback I hope this helps.
Cheers Matt
Add a delay OFF timer for the vacuum to keep running a bit longer.
good tip - cheers
This was super helpful but then I got lost. There is already a black connector for the control panel with a brown wire going into pin 6 the 24v. Do I remove this? Hoping not to make a big error. Thankyou
Thanks for posting the video. Will this work with a Thunder Laser dual air assist (also will be using an external compressor rather than the small pump provided with the laser) or is there even the need? I have just received my Thunder but don't have it set up yet so not at all familiar with the operation other than watching a ton of RUclips videos over the past year. Thanks.
The flow limiter on the pneumatic relay, is that so it can be "off" but still supply a minimum amount of air (blow the stuff away from the nozzle & mirror but not blasting at full strength)?
Hi Matt,
Love your work, could you please help me about wiring diagram of Trocen anywell AWC708C controller. Didn't understand where to connect wires on this controller.
If need I can share pictures of controller
Know this is OLD in technology world but your using a aquarium pump ? And run it off the relay and solenoid ? This is what I was looking to do since I can't add a compressor. So are you still with this setup ? How did or as it worked for knocking out charring and better cutting ? Thanks. Great video too.
Great job on the video and the explanation. What size diode did you use on the relay. They are very tiny and hard to read. The one that I got was completely blank out...
The info I have is Diode = 1A 50V 5x2.5mm
@@MWLaser Thank you Matt..
I have it installed however it will not turn on the air. Everything seems to work up to that point. I would appreciate your help.
This air assist can be used in conpressor as well?
Awesome video, great help thank you! Does it matter which mains feed to the pump you break into? Live or Neutral?
Thanks, I have more info and diagram here - mwlaser.com.au/ultimate-air-assist-wiring-for-ruida-controllers/
Exactly what I needed! I guess I can plug my air pump AND my exhaust fan into the same power board and control them both.
Great video. Purchased one but it did not include a wiring diagram or instructions. Where can I print those out from?
www.cloudraylaser.com/products/ultimate-air-assist-set
Great video! Especially helpful since I didn't receive any instructions with my Ultimate Air Assist kit! I am puzzled, though, by your comments about hooking your exhaust fan to the relay, so when the air assist relay kicks on, your exhaust fan kicks on. But what about exhaust when you're doing engraving and not cutting? Seems you would want exhaust on whenever the laser is running. Only turning it on when cutting would also tend to fog your lens. Am I missing something here? Thanks for your clarification, and thanks for your great videos-- very helpful!
I was thinking the same, would be better to have exhaust fan kick in whenever a job or the laser is active?
also ideally would require a delay (off) to give it time to completely exhaust al the smoke at the end.
With the ultimate air assist kit the relay switches power to the exhaust and the air pump.
When you select Air ON or OFF the relay still turns on both the Air pump and exhaust so they are always ON when the laser is operating. The ultimate air assist kit also includes a pneumatic solenoid, it is that solenoid that turns ON or OFF with the engraving or cut layer options for Air on or off. This solenoid also allows a small flow of air to protect the lens while the laser is running even if you have selected Air off for engraving.
The result is. when you start laser, the relay switches on Air pump and Exhaust, the solenoid controls Air on or off for each part of laser work, then at completion of job relay turns off air pump and exhaust.
I hope this explanation answers your questions.
Cheers Matt
@@MWLaser I assume that is why you added a diverter section of pipe to bypass the solonoid ? ( to allow a small constant flow of air while engraving )
Video was very helpful. When I finished I have the full air all the time, seems the selnoid is always open. Perhaps I wired the toggle wrong. How is the toggle switched hooked up exactly? Thanks
Email me and I'll reply with a copy of updated wiring diagram
Cheers Matt@mwlaser.com.au
@@MWLaser
Nice video matt, any chance you could send me a wiring diag how you hooked up the ultimate air assist and extraction, orcacidiots guide that would be so helpfull, thanks again for info great video
This looks like it could be a good for me to add to mine, just added a 25litre silent compressor. there is nothing to stop it just draining the tank though as it just keeps running
Install a tap on the air line, and the pressure regulator, this will help with reducing the drain on the tank when you're not cutting. If you have the air assist solenoid installed this also reduces the air flow when air is not required.
@@MWLaser awesome thanks for your reply, I will get some taps installed so i can keep the tank from draining :)
Good video. What size pump do you and do you think it is powerful enough?
The basic air pump 70-150L/min is enough, but you are better to have the air compressor if you can. See ruclips.net/video/4P-5nIckybM/видео.html
I have my laser on the way and want to purchase this kit. Can you share some instructions for wiring the relay to the plug with 240v i couldn’t really understand from the video.
I will post a new diagram on my website for the RD Controllers. when I have completed it. I will leave a link below when done. Cheers Matt
I understand pretty much all of it except the last part. Do you not take the existing power cable for the pump to the mains supply and splice the negative and connect this up to the relay switch? i didn't really understand the power socket hooked up at the back...
email me and I will reply with an updated wiring diagram, with a brief explanation. Cheers Matt@mwlaser.com.au
hi matt..appreciate your replys thanks....one further question, you seem to have the flow restrictor dialled all the way in but thats fine as it still lets a minimal amount of air through to the nozzle stop lens fogging...but then you have the ball valve? whats the point of the ball valve doesn't that and the flow restrictor do the same thing?
regards tony ;-)
the ball valve allows manual flow control, without the adjustment of flow restrictor. In most cases the installation of the ball valve is not necessary.
Please add the steps necessary to turn on air assist output in the vendor settings on the controller. I just spent several hours troubleshooting my install and finally decided to go through the controller options.
G'day, there are not any Vendor Settings required to enable air assist. The option to have air on or off is set on the Layers of your work plan. Eg if you have a Layer that is set to cut you open the layer and make the changes there. Eg for RD works open the a Layer of your job, and you will see the option "If Blowing", set this to Yes if you want air on, or No if you want air off. You make the necessary changes on each layer you have for your work. In Lightburn there is also the option in the Layers labelled "Air Assist"... again turn on for Air on, and Off for no Air Assit.
Cheers Matt
I wish I had read the comments before wasting a 2 days finding this on my own. You are absolutely correct. Vendor settings, on the "other" page and make sure the Blower check box is enabled. Neither the WIND nor STATUS outputs will activate if this is not set correctly.
@@MWLaser Matt, Jeremy is correct. I spent 2 frustrating days learning this on my own.
Great video. May I ask a question? I have a laser that already comes with it's own air assist. A little compressor is plugged in the 220v outlet in the back of the laser and it switches on and off while cutting, it works fine. Now i wan't to use more air power to cut thicker material from external compressor. I am wondering if I can just plug 220v solenoid valve in the back where that electromagnetic compressor is plugged and not mess with the wires at all. Do you understand what I mean? Thank you.
Yes it worked.
Hi Matt, great video.Everything ok intil 11.30 minutes on video. I have connected the relay to the controller and now I am stuck in connecting the relay to the power . the compressor does not receive power from the laser so can you explain the following steps to me? thanks
I can assist via email matt@mwlaser.com.au - send photos of your current setup and your query - Cheers
thanks for sharing, what diodes do you use to connect in parallel with the coil?
1N4001 or 1N4002 or 1N4003 etc... Any of those will work.
If you want an "ultimate" air assist, try putting a little air above the lens so it blows smoke away from the top of the lens.
nice tip to keep the lens clean, but that is not the purpose of this upgrade. this allows you to control air on/off during different cutting layers using the software settings
Hi, I recently purchased 2x kits and used the second dpst switch to switch between air pump and workshop air compressor circuits. It works great as I can use my compressor during the day and run the air pump at night if needed. Just wondering if you bypassed the oem air pump switch, I've left mine connected at the moment while testing, but can't really see a use for it anymore. Cheers
great idea - My air pump was separate, so there is no bypass. cheers
Hi Matt,
I followed your YT video on the ultimate air assist that I ordered from Cloudray. All went well with the installation. When I switched the power back on, the machine came on as well as the air pump. As soon as I switched the air pump off/manual, the entire machine went dead. Will you please advise on where to start and look for the issue? I have no power whatsoever. Thanks in advance
Regards
Jaco
I have replied to your email. Cheers Matt
hi Mat, nice video.....
i just ordered the kit, i have a question, in my controller now i have two cables inserted 1 in pin 6 (+ 24v) and 1 in 3 (out1)
when I assemble the kit are these two cables or do I leave them away?
thanks
ps I can only mount the valve without the l? manual switch?
email me and request wiring diagram for the Air Assist Install. Also send me a photo of your current wiring configuration. Cheers matt@mwlaser.com.au
Hi Matt ... Thank You for making this Video ... can you tell me if the Relay can control a 24v Air Solenoid ... I want to hook this kit to my Shop Air. Take Care
Hi Matt .. finally got my Ultimate Air Assist Kit .... I wired everything according to your video ... I hooked the wires on the Relay Terminals 9 and 5 to the Air Solenoid on my Air Compressor .... but it doesn't engage .... should I be using different Terminals on the Relay ? .... and Thank You very much for producing all your Videos :)
Sorry I've been busy - I've replied to your email
@@MWLaser Hi Matt, I'm still waiting for my laser to arrive, but I'm planning to use an air compressor instead of the pump, so the situation will be the same as Boomer088. I think I need to substitute the relay with a solenoid. Am I right? Thank you
I’m trying to install my air assist. However you lost me when you started wiring the switch and the relay. Seams like some parts of the video skipped over some things. Frustrating.
For anyone installing this and not able to get the WIND or STATUS controls to activate... I wracked my brain trying to figure out why I could not get mine to work and finally found the reason. In the vendor setting, on the "other" page, you must enable the blower check box and save those settings to the machine. Mine was not enabled. Maybe I missed this in the video?
Another symptom of this check box being wrong: When the STATUS signal is grounded and then ungrounded by the switch, the controller resets. This had me completely stumped for two days. I was about 10 seconds away from giving up when I found the blower enable check box.
Hi Matt. Thanks for the tutorial. Laser newbie here. I purchased the air assist from cloudray, but cannot seem to get the relay to work. I tried the toggle switch and it will activate the air valve solenoid, but not the relay as well. I removed the switch for now.
To get the air solenoid to work I had to change the vendor settings to “Enable air-assist output - true” in Lightburn. The green LED on the relay is on. I have 3 outlets on the back of my laser that are daisy-chained. I routed the supply from the second one to terminal 9 and then from 5 to the 3rd outlet, where the air pump is connected. When I bypass the relay by checking terminal 9 to the negative on the 3rd outlet my circuit tester shows 124 volts. When I check terminals 9 to 5 I get 67 volts. Do you think the relay could be bad?
Thanks for any input or suggestions.
Possibly yes - email me to discuss further if you need.
Cheers
Matt@mwlaser.com.au
When I added a 50L air assist to my k40 laser It turns on and off by itself, what is the SOLUTION please 🥺?
Hi matt... did you have to change the flow restricter ... or adapt it in any way as some that have purchased this set from cloudray say that the restricter flows the wrong way?
no I don't need to change anything for the kits I install, All installed exactly as described in the video. If you are having issues with yours, email matt@mwlaser.com.au
Hello Matt, thank you for this video. I decided to buy it after watching your video, I thought i could do it!
But now, after receiving the product I have a couple of questions, it seems more difficult:
1. Can I connect the air blower (550w, 220v) to the same plug or just the air pump? The relay switch can support it?
2.1 I didn't understand how did you connect the wires to the plug, (between 11:37 and 12:25), did you remove the old plug wires?
2.2 I am missing some details, relating to the relay switch. Where goes the cable number 9 (and is a power in or out) and number 5 wire?
2.3 Is the controller supporting the power of that plug (as source) 24 volts?
3. The last question, it's a beginner question, but is important what kind of wires I need to buy? 0,5 copper wire, because seems you are using two types one for 220v and other for 24v?
Thanks for your videos and support
Send me an email cheers Matt@mwlaser.com.au
@@MWLaser I have the same questions....
Hi same question please. Tony 😀
Hi Matt, I'm watching all your videos 😊 does this air assist work with the rdc7132?
Yes it should as it also has the same connections for Air Assist as the RDC644X Series
@@MWLaser right it does 😊 anyway i have ordered it, I'll let you know if it works. Thank you
I purchased this setup but am having issues with installing the diode. I'm not familiar with wiring diagrams at all - foreign to me. I'm stuck at 4:19 mark. How do I install the diode and then the wire? Do I bend the tips of the diode 90° down and insert them WITH the wires? Your schematic covers up what you're doing.
Thank you in advance
g'day, to install the diode you can trim, bend 90°and insert in the terminals with the wire. the Line on diode is + terminal
This is great! Does it work with Ruida Controller RDC6442G ?
yes
Where does the relay pin #9 connect to? Thanks.
did you know now?
Thank you for the video, Have one question. I want when job starts solenoid to turn on and do not tur off until job is finished, is there any way achieving that, because while moving around rdc controllers turns on and of solenoid while starting and stopping cuts
yes watch this video - ruclips.net/video/ZbCbLGymNhg/видео.html Cheers Matt
@@MWLaser thank you
hi matt .... im awaiting delivery of my compressor, until then im using this Air Assist in combination with a built in air pump that only turns off if i pull the plug out ...when i toggle the switch it reduces the amount of air considerably i imagine this is to stop the lens fogging up..will this ruin the pump or is normal to be able to regulate the flow of the pump
regards tony
you are right - this is to prevent lens fog and protect lens. As to the pump, there is extra resistance when air solenoid is closed, but I don't believe it would ruin the pump, maybe put in a switch to manually control pump power so it may be turned off after you finish with the laser and not leave it run too long on restricted flow. Cheers Matt
Nice video! I just ordered mine, and I was wondering what you use for the air? A compressor or a fishtanks air that comes with the laser? If it is a compressor, what size would you recommend for a 100W laser?
Just the pump supplied with the machine, for my larger machine I have a lager version of the same 'fish tank" style pump
Just purchased a 80w Laser cutter, I do not know where the other end of the yellow green wire goes. one end is attached to the machine not sure where the other end goes. Thanks in advance.
This is for the earth grounding cable. Yes the connection is a pole screw on the back of the machine near the power output sockets. The grounding cable gets attached to that and a then run the other end to your earth ground rod. This is different in each country and electrical code, and with me not being an electrician cannot give advice on this, I consulted an electrician when making a decision about this on my machine, I'd suggest doing the same if unsure.
With my setup I have been advised that in Australia the earth grounding is the third prong on my 240v power lead and I do not need the additional earth grounding.
Cheers Matt
Thanks for the reply. I am in Melbourne Australia. will ask a few electrician friends.@@MWLaser
Thanks for the help, appreciate it.@@MWLaser
t type of diode is in use here? I blew mine up. The switch has been turning off my controller and not the compressor, any thoughts?
For the diode - The only info I have is... Diode = 1A 50V 5x2.5mm
As for turning off controller and with switch...... check your wiring is correct and there is no short circuit.
Cheers Matt
Unfortunately your diagram covers the step where you put the diode in the solinoide electircal component and how to wire it.
line on diode to Positive terminal
I recently added the air assist upgrade and now my Door Protect kicks in and will not allow me to burn. Why would wiring a solenoid cause the door protect to kick in? (Green light will not light up). The machine came with the air pump wired to 24v and Ground.
check your wiring, send a photo of mainboard wiring and setup to askmatt@mwlaser.com.au and I will try to assist that way. cheers matt
I bought myself such a solenoid. It passes air by default, without supplying power to it. Is this how it should be?
air will pass though when solenoid is switched off, that is by design to protect lens it requires a small air flow. to adjust the air flow with solenoid off use the valve to reduce flow, if you cannot reduce flow enough you can add a better or additional valve.
What type/model diode you used in air assist solenoid?
The only info I have is... Diode = 1A 50V 5x2.5mm
What's the benefits of having air off during engraving?
the engraving does not have the smoke and debris from laser blown back onto the material, giving a cleaner result.
can this be used in RDC6445G. I HAD ALREADY ORDERED JUST NOW.
Yes works on RDC 6445
Just ordered trocen awc7813, does this controller able to do air assist as well? Thanks
Yes it does - this video shows AWC7813 - ruclips.net/video/_MgA9D4wh-8/видео.html
@@MWLaser yes, i bought it after watch this video but still have to wait it to arrive. Great video
Anyone with rdc6445 can check voltages between GND wind and status when laser is iddle and when work?
On the RDC6445 the STATUS and WIND are both GND terminals. They are switched to GND when they are activated. In other words when machine is active for STATUS or WIND they are switched on to GND and you will have 24+ VDC between the 24V terminal and the STATUS and WIND. When machine does not have active STATUS or WIND they will read 0 VDC
Thank you. So its a issue with my driver...
You might be hitting the same problem as me. In the vendor setting, on the "other" page, you must enable the blower check box and save those settings to the machine.
What is the purpose of the solenoid valve? If I'm interpreting the schematic symbol correctly, the solenoid allows unrestricted flow when the air pump is off (but since the air pump is off, nothing is flowing), and volume controlled flow when the air pump is on. Why not just put the volume control in line and skip the solenoid? I get using a solenoid with an air compressor (though I don't think this specific solenoid configuration wouldn't work with an air compressor), but I don't understand it's application with an air pump. Can anyone clarify? Thanks!
The air pump/air compressor is always ON supplying air to the the solenoid valve (SV).
The SV the RESTRICTS the air flow to allow a minimum flow when you select Air OFF on the cut layer in the software. (This protects the lens from smoke and fumes getting to the lens due to the positive pressure).
The SV opens to provide FULL air flow when the Air ON is selected in the cut layer.
@@MWLaser - Thanks! Makes perfect sense now.
Does anyone know if this will work with the Top Wisdom controllers?
yes
Can I control air assist with Ruida 6432?
Yes. 6432 is compatible with air assist solenoid.
@@MWLaser okay, thank you
Would this also work with the Ruida RDC 6442s?
Yes
@@MWLaser Thanks Matt love your videos!
@@MWLaser one other thing my kit only came with two diodes isn't that all that's used in this setup
@@henryhartsfield4574 yes one for the solenoid and the other on the relay
Why the solenoid on the air line? Just turn the pump on and off. Unless your running a tanked pump.. Then you want the air solenoid but only that.
you always need air. when I mention air on or off it is actually ON= full air and OFF - low air, just enough to protect lens. if you have NO air then the lens is unprotected and there is more chance of fire starting
What gauge wire should be used?
You can use 18AWG
@@MWLaser Thank you! One more question: Does each side of the diode go under each screw terminal? Or does it get soldered where the beads of solder are?
@@mpark0 Yes the diode legs can be trimmed a bit shorter and use the screw terminals to secure. the "white" line goes closest to the Positive Terminal. Cheers Matt
@@MWLaser for the switch, the two static pictures shown in the video seem to differ slightly- in one photo, it looks like the ground wire is soldered across the middle two pins and in the other photo it looks like it’s soldered across the terminals opposite of the wind and status connections. I guess my question is, where does the black ground wire go on the switch pin and does it get soldered to one pin or across two?
@@mpark0 Black Soldered Across the middle two pins of switch
Great video sir, i have been running around to get those parts,is there way i can contact via email or whats app
Do you really want the air pump to turn off? By the look of that solenoid, it allows a little bit of air through a restrictor to keep air flowing through the head even when air assist is off, I would imagine to keep the lens from getting fogged. Surely if the air pump is off, this feature wouldn’t work.
The air pump starts at beginning of job, and remains on until the job is completed and then switches off. The solenoid controls partial or full air as set in layers of the job. So air is protecting lens from fogging throughout the entire engraving and cutting process.
Cheers Matt
Links are dead :(
New Website - Links now fixed - thanks
Hmmm.... I did get the smoke.... :-( Luckily the laser is fine
Glad to hear you have it resolved - Cheers Matt
How do we make sure this doesn't happen? I'm so scared to do this upgrade but want to so bad. I will be hooking up to a compressor
@@lorirodriquez6100 If you put the diode in backwards, you will get smoke. The end of the diode with the line goes to the + terminal of the relay and solenoid, which is directly connected to 24V.
Oii
Thanks as always Matt, your videos are great. Still working on setting up my laser. Have the ultimate air assist kit and just waiting on compressor to arrive. Since I'll be using a compressor rather than the air pump, do you think this would be a good way to go to keep the air from running all the time?: www.amazon.ca/dp/B07BW21Z5M/
sorry, because of the link this comment was hidden.
YES that is the same units I have recently purchased to add onto the air assist system to eliminate leakage from air compressor while the machine is not in use, I am currently preparing the video for installation. Cheers Matt
