How To Build a CNC Plasma Cutting Table | Part 6 - The 1st Cut
HTML-код
- Опубликовано: 4 янв 2022
- Welcome to part 6, the final video, in the series documenting the build of our CNC plasma cutting table. In this video I'll show you the completed table set up, including the torch mount, the ohmic sensor, the CNC port connection between the plasma cutter and the plasma interface unit, the air compressor and moisture filter.
You will also see the 1st cut of a piece of metal on the table...and the excitement that moment brought.
The final things to set up are the water table, to trap the fumes and sparks from the cutting process, as well as upgrading the electrical enclosure to a larger cabinet.
I'll then fabricate a console on wheels, with the enclosure mounted at the rear and a bench top for my laptop and possibly a monitor, too.
This will allow me to position myself close to the torch, in order to correctly align it on the work piece prior to cutting it.

Hi. Watching your videos, I found it probably one of the best so far that can give people guidance on what to buy and how to build a CNC plasma cutter.
Thank you. For me, it is the best inspiration so far after watching so many other people.
Hi Emanuel and thankyou for your kind words. I'm glad you found my videos helpful and maybe inspired you to build your own table. I do sell plans for my table build....if you're interested, feel free to get in touch.
Thank you! I enjoyed the whole series very much. Looking forward to building my own.
I'm glad you enjoyed the video series and I hope they help you with your build.
Well Done.Thank you for taking the to share such a great build👍
Thanks Shane, I hope you enjoyed the build series.
I keep playing back your reaction, I love it, and feel it. Great series and out of all the research I've done, I'm running you ideas. Simple and obviously effective. Thanks for all you time and effort you put into this. Right, now it's my turn to give back to RUclips... Cheers from NZ.
Hi Shayne, I'm glad my videos have been helpful to you. I enjoyed making the table, and the videos were a way of documenting the build. I was confident that it would work, but when I made that first cut, the relief was huge.
Awesome job mate
Thanks Vince....I hope you enjoyed the video build series and it helps you if you're going to build your own table.
Thanks for all the effort, and helpful information in the videos of this series, gives one a good understanding of all the things needed to get up and running, and making your own parts. Cnc plasma cutting tables. The results are impressive.
Thanks Ebrahiem, for your comments and I'm glad you found my videos helpful. Look out for more videos as I cut new designs on my table.
congrats. excellent results for a first cut.
Thankyou Len, it was a great relief to see the table cutting some metal parts. It's been cutting quite a few things since!
Hi MR Rusty thank you so much for sharing I really love your work.I have a table I build and I'm also using my plasm controller.I'm having trouble with cutting holes not getting perfect round holes any advice.
Hi Melvin, if you want to send me an email, I'd be happy to try and sort your your issues.....rmhyde58@gmail.com
Well done mate. Thanks for sharing. Cheers Robert
Hi Robert, thanks for checking out my videos and I hope you find them helpful.
Good to see it working and welcome to the dirty lungs club❗
Hi Ross, the table sure generates some smoke, sparks and dust. I picked up the water pan yesterday and once I've got it installed, along with the slat frames and slats, I'm hoping I will have a cleaner working environment!
I've subscribed to your channel as I'm keen to check out your videos...keep them coming.
@@RustysMetalCutSignsDesigns Thanks for the reply, If you let your imagination run wild it's amazing what you will create from the machine. I'm from Brisbane but moved north to Thailand, been here 11 years now. so i needed a hobby to fill in the days. PS drop a magnet the wall and you will shocked at how it will look after a while!
You have done a great job on this build I may have the confidence to do it. I have built my own cnc router it was not bad currently started on a co2 laser build. Going to do the plasma next. Again nice work.
Thanks Randy. I had no experience with plasma or CNC stuff before this build, (although I have welding and fabrication skills) and it wasn't that difficult to put the whole thing together. If you need any help with your plasma build, my email address is in the About tab on my channel....happy to help if I can.
Awesome work Rusty.
We use an Unimig cat 45 as well and have been trying to figure out if there was a good way to run ohmic sensing. Your solution is awesome !! Great work on the cnc build.
Hi slo78u, glad you found the video helpful. If you are going to set up ohmic sensing similar to the way I did it, make sure you make the fingers of the stand off guide long enough to have 0.5mm clearance for the cutting tip...ie. the cutting tip should be 0.5mm above the material when the fingers make contact with the work piece.
Then, you have to change the setting for your cutting height, to allow for the tip being 0.5mm high already. I run my cutting height at 1.5mm, but because the tip is already sitting 0.5mm above the work piece when the ohmic sensor detects the material, my cutting height is set to 1.0mm in the software.
Also, watch for slag build up on the tips of the fingers, which change the cutting height of the torch. Hope this makes sense.
Wow well done rusty it looks and works the mutts nuts Iam going to build one like this I’ve nearly got all the parts to start the build hope it’s as good as yours 👍
G'day Philip, glad you liked the build series. I've been cutting a heap of small parts, as part of my 'fine tune the table' and pretty happy with everything I've cut so far. Now it's onto some bigger projects.
If you need a hand with anything on your build, don't hesitate to get in touch....my email address is in my channel's About tab.
Hello Rusty,
Great system that you built there.
I like the simplicity and the professional implementation
Thank you for the documentation and the inspiration
I am currently in the construction phase of a combined milling and plasma CNC system
Greetings from Germany
Hi Harald, thankyou for your kind words. I learnt a lot from other people's builds, which gave me the confidence to tackle my own, which I'm glad I did. Buying a table would have been so much easier, but there's a great deal of satisfaction in doing something yourself.
Good luck with your build....will you be posting videos on your YT channel???
@@RustysMetalCutSignsDesigns Yes, it is always easy to buy something, but often it is about the path and the success of having created something yourself.
I looked at many different constructions and yours particularly appealed to me.
Yes, I can post my first video from yesterday 🙂
I look forward to seeing your build videos.
I've already uploaded it.
It's only a short video, but you can see very quickly that I have orientated myself very much towards your construction
That's a good looking table, Harald. Looking forward to seeing more videos and to see it finished.
Good Morning. Just wanted to check and see how the machine is holding up? Have you considered selling plans or dimensions for the build? We were able to get a build cost idea from all the information that you provided in all the videos, but the size of the table was in question. I appreciate the videos and all the information you have provided within.
Hi Melissa and thankyou for your kind words. I have been considering selling build plans, parts list and a wiring diagram for my table...would that be something that you are interested in?
Yes Sir Mr. Rusty, we would be more than interested. and Thank You for replying so quickly. My husband was very impressed with your unit compared to all the other DIY's that he has been researching. He is a very quality driven individual and enjoyed watching someone who took pride in what they were doing, resulting in a quality product. If you would be willing to sell a set of instructions, we would definitely be very interested.
@@melissaannoverstreet3103 if you would like to email me at rmhyde58@gmail.com I'm sure we can work something out for you.
Can you tell me how much money I'm expecting to spend to build one like yours you did an excellent job this is been my dream to build one like this and make items to sell thanks again you were awesome
Hi Jerry and thankyou for your kind words. I'm all in at just over $5000 (Australian) for all the parts, including the machine torch...but without the compressor and plasma cutter. Add in another $2300 for the big 3 phase compressor and $1300 for the Razor Cut 45 plasma cutter.
If you have any questions or need help with your build, feel free to email me at rmhyde58@gmail.com
Hi Rusty As I have already mentioned to you on another group, I am planning to build another machine during the coming winter. I have been reviewing your series for several times and will be referring to your project for my next build. I noticed that you are not using materiel detection, only the ohmic sensor; is there a particular reason or just a personal choice? Thank you again for this series, a superb good reference.
Michel
Hi Michel, I'm glad you found my video series helpful and all the best with your upcoming build. Ohmic sensing is one type of material detection...the other options are a floating head or manually setting the initial cut height using a 1.5mm (or 0.060") feeler gauge.
Hi Rusty,
I'm in the process of designing a CNC Plasma table and am inspired by your videos. I was wondering, about the accuracy of the cut out parts compared to the CAD design dimensions. Do you have any measurements?
Best regards from Switzerland,
Higgins
Hi Higgins and thankyou for your kind words. when I was doing the drawings on the table in part 5, I was very happy with the dimensions of the drawings, versus the actual toolpath.
I'm still playing around with lead ins, offsets, etc within the software, to create parts that are the exact size of the CAD design...I think I'm pretty close.
👍👍👍👍👍👍
Glad you liked the video, thanks.
Fantastic work Rusty, I would like to replicate your design but where can i get the spare parts and how much would the whole project cost here?
Hi Mach ug, thankyou for our kind words. I hope this video series will help you to build your own table. The parts were listed in part 2 and part 3 in the video descriptions. I bought most of the parts on eBay...the MyPlasmCNC controller and plasma interface unit were purchased online from Automation Technology in the USA, as the manufacturer, Proma Elektronika, were out of stock of these components. Here's their website shopping page for the MyPlasmCNC motion controller, plasma interface unit and other parts they sell...sklep.proma-elektronika.com/
The parts bill for this build was AUD5000, not including my labour. I was going to buy a table from the USA and the cost to purchase it and ship to Australia was close to AUD8000, but that table only had a cutting area of 1225mm x 845mm, where my table has a cutting area of 1340mm x 1340mm...enough to take a half sheet of steel.
If you have any questions or need help with anything for your build, feel free to get in touch...my email address is listed in the About tag of my RUclips channel.
Well done with the plasma cutter table and are you going to get a vertical torch eventually?
Hi Colin, thanks for your kind words. I'm not sure what a vertical torch is?
@@RustysMetalCutSignsDesigns Hello Rusty, a vertical torch is a straight up and down torch used in CNC plasma tables, the one you are using is a hand torch, I have seen other builders using a vertical or pencil torch, they are advertised on eBay and Amazon.🙂
Hi Colin, I understand what you mean by a vertical torch...I call them a machine torch, and yes, I've been looking for one that also incorporates a shielded end so I can still run my ohmic sensor, but I've not found one yet.
I know Hypertherm make a machine torch with a shielded cap over the cutting tip, but I don't think it's designed to fit into my Unimig plasma cutter. Unimig do offer a machine torch but it's basically a 'straight hand torch', using the same components and consumables....no provision for ohmic sensing, other than what I've adapted to fit my hand torch.
Great Work Rusty I have built a CNC before But yours is is great just wonder were you goy the Z Axis Actuator kit complete from?
( maker store?} And would you mind if i emailed you about some specifics as im over in the east and planing on building the same. I already have Nema 23 and drivers, Any way great Job...regards Ross
Hi Ross, the z axis unit was an eBay purchase.
Yes, feel free to email me. I'm up the bush at the moment so will reply when I get home, or if reception is OK, will answer sooner.
@@RustysMetalCutSignsDesigns thankyou
Can this table be fitted with a router for wood cutting?
In theory, yes. The torch mount on the Z axis could be removed and a router mounted in its place. I'm not sure what sort of software is needed for operating a router, but a wood router table looks very similar to a plasma cutting table, so I would imagine my table could be adapted.
Some of those parts look familiar 😆
Hi Rob, they say 'imitation is the sincerest form of flattery'....I liked the way you put your tables together and your design made sense. I might have gone overboard with the support table, instead of just welding legs to the main frame...but we'll probably do that on the next table I build....a full size one. Thanks again for your helpful videos.
