Put your ground rod outside wherever possible & run the lead to the machine. You are the first person to discuss the need for a large air compressor & the duty cycle of the plasma cutter, WELL DONE!

[@PortfireStudios]

Hi David, I just wanted to say thank you for sharing this video. I appreciate your honesty in sharing your mistakes and subsequent learnings. You have saved me from making many of the same mistakes in my own build. Well done and keep them coming!

[@SteveSiegelin]

Okay so I just bought my first plasma cutter. Nice unit but it was broken when I bought it. The gentleman I bought it from could not figure it out. I took my time downloaded all the manuals and tracked all the systems. It only took me two weeks to get this one working. Plasma cutters are usually pretty simple if you happen to buy a used one that's not working. Make sure it at least turned on and air flows before you buy it though. If it does not turn on most likely the main board is bad and it's not worth the used price. I picked up mine for $200 and it's a PCM 750i so this is the one I will be incorporating into my table! I'm glad to see a lot of people building these things. I have access to one all times it's such a massive machine though that I'm not cutting any steel that size I've seen him cut upto 4 inch thick Steel whereas my machine will only do about an inch-and-a-half maxed out! Another word of advice is run about 40% of the duty cycle to keep the longevity of your unit

[@jjgoyn5324]

This is the best tutorial i have seen ever.

[@jbodden6977]

hang the cables from the ceiling and use swivel support arms and weights to maintain tension... using weights allows for 'floating' movement instead of like fighting a spring when the changes in head position occur.

[@dominicgoodwin1147]

This is the absolute gold standard on how tutorials should be made. Informative, thorough, well researched, clear, easy to follow. It shows what went wrong and how it was fixed. It shows different alternatives and the factors to consider when evaluating alternatives. I don't think I have ever seen a better designed and presented tutorial. Well done.

[@DrDFlo]

Thanks for your kind words!

Noise mitigation Easy - have a separate cord that just connect outlet ground to the water box. Have your power supply plugged into a filtering power string and the box connected directly to the ground of your outlet (possibly a plug where only the ground is connected). Also separate power supply from frame with an insulator (e.g. mount to wood mounted to frame) Medium - some power supplies have dc- connected to AC ground. This can be tested with a multimeter with everything unplugged measuring resistance between negative terminal and ground terminal of power supply. If there is a connection get a better power supply (I think meanwell have isolation, based on online diagram). Hard - what you really need to do is isolate the ground of the processor from the ground of everything else, which is something that would have to be in your controller. A 5v dc-dc isolator (b0505S-1wr20) is a couple bucks used in CAN bus electronics. But you probably can't do that reasonably.

I don't know if this is elsewhere, re Compressed air, you do not want "contamination" as in oil or particles coming out of the plasma nozzle, it must be clean air. I use a "oil less" compressor. I added a "air filter", "dryer", and "de oiler" at the output of the compressor. I also use a "as short as possible" & "dedicated" air hose, meaning it is only used for the plasma cutter. And if you can use a 3/8 air line from the compressor to the plasma is better (more volume!) Additionally, I added two "portable" 10 gal. air tanks to the line. This addition is way cheaper (about $100) than it would be buying a new and very "large" compressor. It adds volume which increases the duration of "air time" to my unit, it also helps even out the "pulse" when the compressor kicks in and out, making for a more "even flow" of air. I'm using a Lincoln electric tomahawk 625. The air compressor is a Porter Cable 3 HP, 4 Gallon. This setup works easily for a 4 -6 foot cut in 1/4", and up to 8 foot in thinner material, which covers just about everything I do. If required, you pause in a cut and allow time for the compressor to recharge for longer cuts.

[@lds113]

Hi, I don't know if you still want to try it because it has been some time you posted this video already and you bought another machine but... I am an electronics engineer and have worked with EMI for some time. What I would try first to solve the HF interference issue is: -Route the plasma cutter negative cable as close as possible to the torch cable. If possible moving the ground connection with the cutting head to minimize the loop. -Adding a choke around the output cables instead of everywhere else can be helpful as well. -Try to shield the spark gap in the HV generator inside the machine. If you or anyone else reading this comment try any of these, let me know if it helped. Nice video !!

[@Land-Rover-Discovery-Adventure]

The best tutorial I have ever seen! wow

[@creamofbotulismsoup9900]

There are plenty of easy to print heat resistant filaments out there. Annealed PLA is pretty awesome but there are polycarbonate and nylon blends that have desirable properties that can be printed on a relatively ordinary printer. Overture easy Nylon and Polylite PC mainly come to mind but there are others. ABS is a very good option for building mounts, brackets or other structural parts, it's fairly heat resistant, it doesn't deform as bad or has a tendency to crack over time like PLA or PETG does. Then there is ASA which is very similar to ABS but is more UV resistant, and assuming it doesn't go above 100C would probably be perfect for a mount.

[@markofarrell4040]

With regard to the noise issue, there are two ways to induce noise into a cable: Electrostatically i.e. capacitively and magnetically. The insulating of the table from the work piece reduces the electrostatic portion, but the magnetic part is made up of a loop which is bounded by your cutting current cable and your grounding current cable. The greater the area enclosed by the separation of these two cables the greater the inductance and thereby magnetic coupling to other devices cables. It also makes the electrostatic worse because the ground cable becomes more inductive, allowing the workpiece to radiate electrostatically as well. To reduce the inductance run the ground and the cutter cable as close to one another as possible for as long as possible(their magnetic fields will tend to cancel one another). Only let the ground diverge from the cutter current cable for as short a length as possible to connect to the workpiece. It will massively reduce the inductance and that means that the ground cable and workpiece will act more like a ground. Hope this helps.

[@TheAlastrina]

insulate the black box from the frame. and ground the shielding to the black box. Only ground one end of the shielding.

[@tcratius1748]

Absolutely love it! To help you lead screw last longer you can add a dry lubricant as it does not bind with dust and other particles in the warehouse environment and lubes. I have seen these screw painted with a dry lubricant as well, however, I do not know what the process is. Nevertheless fricken awesome dude, you damn well read my mind. Just got to figure out where I can put it lol.

[@DrDFlo]

Appreciate the lubrication advice!

[@teresashinkansen9402]

This dude looks like a mixture of styropyro and Carl Sagan. Very cool projects

[@Greolt]

The thermal dynamics is a good machine, however if wanting to stay with a cheaper cutter there are many examples of machines similar to your first , that have pilot arc. I use a ltp5000 which is an inexpensive pilot arc plasma. I run the torch lead in the same cable chain as the stepper cables and it works with no noise issues on my diy cnc plasma. Most of these use a SG-55 or AG-60 torch. There are cheap straight versions of these torches.

[@rodrigoenriquez2747]

Recommendation, insulate the water table from the machine fram, print PLA or PC spacers that separate it from the frame itself and you should be more capable of using AC start on that plasma torch, that way you can also just ground the water table to the Plasma generator rather than reply on a clamp to the work piece. I recommend also adding a drain port to the water table

[@DrDFlo]

I'm working on the drain port! Adding a welder here shortly to the shop.

[@fawkyooo7377]

Giving your slats a slight bend makes them less likely to wobble with gantry movements. Also makes it less likely to line up a slat with a straight cut causing cut issues.

[@sspence65]

opto isolators for the limit switch can help decouple noise.

[@steeltree-fabricatingandcu3796]

It’s grounds everything needs to be grounded Lots of grounds Should help Drive a ground rod outside Come into the shop with a large braided copper wire obviously being close to the ground as possible

[@johnellis1952]

Re: the compressor air flow....could you simply add a second compressor (identical to your existing unit) and 'T' the output lines into the cutter? I have a California Air Tools compressor and I love its performance and quietness, so I understand not wanting to change. Good luck.

Can I change Y and X axis for bigger one so I can fit sheet 1x2 metres and everything will be alright?

[@DrewTeter]

Can you use a Y adapter to have 2 different air compressors work together? Each compressor supplying ~4cfm at the same pressure into the adapter, giving you ~8cfm out the adapter. Or is this not a thing?

[@paulsomero]

Yes. Depending on the type of pump (s) you might need check valves so as to not have the teed pressure overload one pump or the other during startup, but most respectable compressors will have a head relief valve that blows off that head pressure so startups are softer...

[@Projectblackkjack]

Use a gun scope mount to hold the torch

[@geedon1]

Awesome work. This has been very informative

[@MrDabrudda]

Ground the aluminium frame to the ground wire on any 3 prong outlet. (test the outlet to ensure the wiring is indeed grounded) Put a rubber pad underneath the water pan to isolate the frame and pan. Ground the pan and the plasma cutter. Buy a metal box big enough for the controller. Put the controller inside the metal box and ground the metal box. Any air cooling openings in the metal box should be covered with metal screen or metal mesh to prevent EMI. In otherwords...GROUND EVERTHING!

[@DaftFader]

You should get a lapel mic dude, I had to turn the sound up loads to hear you properly but the background noise makes that unpleasant. With a lapel mic the signal to noise ratio will be much higher giving you a much better sound quality, isolating your voice so you can be heard more clearly. ;)

[@bikefarmtaiwan1800]

It is a great video and super informative but if the audio was better it would be twice as awesome.

[@larryrobinson7492]

Plasma outside cuts should always be clockwise and inside cuts ccw, keep the cut to the right side relative to direction of cut. Think of it as climb milling. Not sure why you are talking in metric, you seem to be American to me and I'm sure most of the viewers talk in inches. Nice work by the way.

[@guypatts494]

Thanks learned alot from this video

[@stephenburgess3828]

Remove your power supply and stepper controller from the plasma cutting machine and you will eliminate the noise - the power supply and the stepper controller use their chassis as ground reference, and the noise will back feed into the electronics and cause problems (I'm surprised you haven't burned out the 24V power supply)

[@zaremiadraigtmoore324]

Hallo D-Flo, You have mounted two switches on the floating head. One for the floating function of the floating head The (other), I guess, is for the total Z-Axis. Are these switches wired ORs? Or is the switch on the floating head used as “Probe” Function on your controller? Great video, keep up the good work! Best regards, Diego

[@theodorenickel7462]

Hi Dr. D-Flo, Good video. I am about 2 years late and I have not read all the replies to your original video, BUT, had you thought about isolating your water pan from the frame and maybe even coat the inside of the pan with an epoxy or some reasonable facsimile to isolate the water from the pan? Just a thought.

[@timothyball6608]

It would be cool to add an attachment to do CNC pipe notching/cutting.

[@eliworks8549]

I wonder if with the first plasma cutter, you ground the cutting tip directly to the ground clamp. Tricks it into thinking that the tip is touching the grounded part and giving a clean path to ground. I hope to test it if my mpcnc works. I'm also going to use a SD card to eliminate the USB cord from the computer.

Your hand torch is ok for the thin flat material but it is not suitable for thicker material. the hand torch will be melt by heat. It is necessary to use the machine torch to solve this problem.

Insulating the drip pan should be easy, Seems the Blackbox controller isn't build with enough EMI protection, a metal case for it would perhaps help. Automatic height correction, with an inductive sensor will be difficult. Building a core xy with a manual height, where the steppesr are isolated from the frame would be a cheaper way to go.

[@DrDFlo]

Core XY is definitely an interesting solution...

I'm impressed Doc! Looking forward to more videos. Love'n learning about the plasma. I have had this in my mind for quite some time, are there going to be slightly larger tables available as a one click purchase option coming up. Not taller, Lol

[@DrDFlo]

Glad you are enjoying the channel! Regarding your question about larger tables, it is unlikely that anything larger than 1000 mm x 1000 mm will be available anytime soon as a one-click purchase. I don't speak for OpenBuilds, but this system uses lead screws and a longer table would require either timing belt or rack and pinion (preferred) instead of lead screw.

I have one question; what type of plasma cutter do you use- one with pilot arc starting, or high frequency starting?

[@DrDFlo]

William, this is a great question. First off pilot arc is not a type of arc ignition. A plasma cutter with a high frequency start can have a pilot arc. For CNC applications you need a plasma cutter with a blow back start (blow back start + pilot arc is ideal).

while school systems are different, consider speaking with your local tech school welding instructor. that is an easy welding project, and if you supply the materials, most schools will do the work at a very reasonable rate. (last time I had some welding done (sealing the leak in the fuel tank of my motorcycle) about 6 years back, it cost something like $10 per semester to have "access" to the programs, and $5 per project to get the welding done. (I am planning to put them to work again in the not too distant future building several parts for my truck such as a custom cargo rack (mostly because I do not have a tubing bender, or a place to set up a welder)) the students generally enjoy getting to work on real world projects instead of just welding scrap metal. Keep in mind some projects might involve more than one "work order" meaning they can tack on additional fees for services... this can add up fast when you need something like the machine shop making 5-10 parts for your single project. --------------------------------------------------------------------------------------------------------------------------------------------------- it is true that most fabrication shops do not want to mess with one off parts...it is a lower profit margin. after all... that might take someone on a metal brake all of 10 minutes to make the 4 bends in a cut piece of material. someone is going to spend maybe 5 minutes per corner setting up and cutting the corner notches, then someone is going to spend another 5-10 minutes with a tig welder sealing up the corners. on the other hand if they are doing batch work, they might be producing 10 parts an hour for someone ----------------------------------------------------------------------------------------------------------------- on the other hand, the you's and me's, we would just cut 4 strips and weld them to the base, maybe even weld in a train bung if we make the pan out of mild steel, we maybe have $80 US invested in the materials, and we spend an hour or two laying out the pieces cutting them, welding them, testing for leaks, fixing the pinholes we missed :)

[@michaelkincaid9582]

you could have a ground loop issue. Make sure each piece only has a single path to ground. Unplug all the power cords and make sure there is no continuity between grounds on different plugs. Otherwise, current can run through one cord, through the wall, and back up another cord. An often forgotten path is through the USB cable and through the computer, so buy a USB isolator. Another possible unwanted ground path is on that torch trigger, so check that circuit. Elsewhere, use plastic or ceramic mounting hardware, or relays and optocouplers

[@krstemukovski4953]

I had the same problem with the noise resetting my controller. I tried everything you mentioned, at the end i made a box for all the electronics separate from the machine on the left side, and the plasma cutter on the right side. No such problems since. I use a cheap plasma cutter. I Hope this helps someone to not go through a month of troubleshooting and fried electronics :)

[@AndreasGosch]

You should still construct a water tub as a spark arrester below the bed. It should be slightly slanted so that the metal residue collects in a corner and can be easily cleaned.

[@williamdeacon3981]

Very good tutorial, it covers a lot of important points and is very informative. The only thing I'd say is that although the leadscrews are protected by the C-beams, metal dust and debris will still come in contact with those screws. I know this because I operate a plasma CNC for work every day. So I suggest that accordian style dust covers be installed to protect the leadscrews. But otherwise excellent tutorial. PS: Rack and pinion is also typically used because it offers a much higher rate of speed, which is ideal for plasma CNC machines that have a more powerful power supply.

[@TauCu]

the cheap pilot arc machines are horrible. some are even non-isolated (and thus can happily kill you if you become part of the circuit) Just get a good Jassic/Unimig or Cigweld cutter. specifically look for devices with Blow-back start and not HF start.

[@codecisrl7849]

I think this may be related to the fact that the desktop is sharing the same electric network as the plasma cutter and the noise is coming from there, maybe adding a UPS to the desktop might help filter the noise

What's the budget for everything Sir?

Regarding a 3D printed torch holder: Consider printing a mold for the part, or casting a urethane mold from the original PLA part (well, an unmelted version of the part). Cast a new part in hard silicon. The silicon part (being a thermal set rather than thermal plastic) will be much more robust mechanically and thermally.

I have been thinking of buying a cnc plamsa cutter to use with my hypertherm 45XP. I dont have many options to choose from living in New Zealand. I could buy a really to go unit called the SWIFTY 600 (made in UK) 600mm by 600mm cutting area but costs NZ$13000 and it comes with a HyperTherm and they didn't want to sell the unit with out the cutter. then saw another UK unit called XtremePlasma and thats around NZ$9000. Came across the crossfire cnc plasma cutters and i was ok with the pricing but they wouldn't send to NZ. So after watching your video a couple of times over the last week and I asked OpenBuilds a couple of questions I am going to get the Lead 1010 router and make it into the cutter.

[@CPUDOCTHE1]

Great video. We built a 4'x9' CNC Plasma cutter about 4 years ago. We thought about building our own controller or going with one of the cheap ones. We went with a commercial quality controller and did not have any problems with EMI. The torch cable is in the cable tray/chain. We milled the torch holder out of aluminum and use a couple of magnets to hold the torch holder to the z-axis. The HyperTherm 45 will cut up to 5/8" decent but when we cut thicker stuff, we can mount an oxy-acetylene torch on it. The HyperTherm has voltage sensing so the torch height is adjusted automatically while cutting after the initial pierce. After the initial build, we made the gantry higher and mounted a chuck on the table so we can cut up to 6" diameter pipe. I guess we are going to build a CNC router now.

David, I have a question for you. Since the water pan, slats and job material sit directly on the frame extrusions and the ground clamp is connected to the work material, do you think that insulating the water pan from the frame would help with EMI?

I can only afford one plasma cutter and decided to go the cnc route after I purchased the Bestarc. Thanks so much for your content..
