I thought I’d make a quick video about the Arduino based CNC Plasma cutter that I made in the farm workshop.
EM interference was a major issue however, to overcome this I;
Used shielded wiring
Installed a stainless steel water bed
Put ferrite magnets everywhere
Earthed everything I could
Major parts include;
Arduino UNO
CNC shield V3
1.9Nm Nema 23 Stepper motors (2.8A)
24V Power supply
DM542T Stepper driver
HIWIN HGH15 linear rail (A must have item for an accurate system in my opinion)
5V 1 channel Relay Module with Optocoupler (For on/off plasma arc)
“Tool Mate” Plasma clean from Hare and Forbes Machinery House
Software im using;
Arduino IDE for flashing the arduino
Fusion 360
Universal G-code sender
Post Processor: https://gist.github.com/michahump/8a2fc584ac653bd8bd72bc5547a89862

I like it
C'mon, man. You got a half-million views on this video. Show us some updates!
Thank you.
Hey i have the same problem with the emi keeps blowing my arduino how can i sort this problem out using a hf plasma can't find another one
Good job. You looks like Alexander Zverev.
can you add on description for wiring the optocoupler?
Nice one man, for emf shielding, it could be coming back down the wires from the stepper coils, (had this problem with dc motor). To fix it, maybe add a diode or decoupling capacitor close to arduino and/or motor control boards.
are you using those big driver modules for the x and y and using a standard mini driver for z?
Nothing in the world beats the genuine Australian accent well done mate
Great job!!! Can you help me witch Arduino Uno? When cutter is enabled arduino disconnect itself… what i doing wrong???
Did you make the table as well?
I know I’m late to the party. But could you use a spray mist nozzle or does it need to be a decent flow of water to keep the work piece cool??
Can you share the blue prints?
Very nice!!!!!!!!
Большая просьба,помогите с
приобретением электроники
для данного проекта.
I'm jelly.
Ey compa, genial laburo!!
Do you have the parts list and hardware,temples I like your machine
Very good! . What kind of interfaz software do you use to control whit arduino?
This cut, terrible …
Post-processor is missing , can you update ……thanks
FuuuK yeah !!! Thx heaps for this. note: Got me a Unimig Viper cutter (only a 30) but hope to convert my CNC machine to a Plasma. Machine is a DIY " LOWRider 2" What Compressor your running for these jobs ??
Can you give me a detailed drawing, a list of materials for this CNC machine?Thank you very much.
Hi where do u buy the motors and control
Thanks for the walkthrough. I wouldn't know what to do about the EM stuff otherwise
Crikey that's one of the simplest designs i have come across yet brilliant 😉
hello this little relay I can use it on a 70a cutter
Very nice. You are a motivation to others.
What a fucking legend
.
What motor did you use for the torch height control? Is it a Nema 17?
Would you have a wiring diagram of your system you could share?
That's cool. I want to make one.
Brilliant job, where in Australia are you located mate?
Great Work! want to make my own someday!
Hey great job. How do you deal with backlash using the rack and pinion drive?
maybe speed the motor up a tab it may lesson the slag, great job
you could use a capacitance based system for Z height. Like on a digital caliper…put a metal wheel on the torch holder that can move freely up and down and then use the output from it to alter Z height. iGaging has a digital caliper that has a USB out port on it and you could just attach a little sealed bearing as the wheel so the height is constantly measured. kinda hard to explain in words but if you saw it on a napkin you'd understand in a half-second.
Hi, great project! What's the size of the table? And what profiles did you use, i.e. height x width x thickness?
Very Nice!!!
Torch height control will help with reduce the Slag, but your biggest issue is your water cooling is to efficient and will not help with reducing the slag. Also slow down the speed
hey any chance you may have to repost the post processor? tnxx!
Nice work. I like the coolant and torch holder too.
Thank you so much for sharing this amazing experience !!!
May i know your contact number!?
Great job! You have inspired me to make my own setup. Anybody that would give this video thumbs down has either,1failed miserably at trying to build one of these or 2 just plain and simple doesn't understand how technical this stuff is and how you got to have a pretty good mind to set this kind of a rig up.
Oh..or 3 Jealous!
Awesome machine. Do you need an Arduino that supports 4th access to start and stop the firing or was that the relay. A vid on the electronics would be very useful.
I might be guessing, if you set your feed rate little higher you may get less slag.
Wow this looks 100 % awesome and looks like it might be affordable, really appreciate you sharing all the details well done
