Amazing ! Thanks for sharing, I might do that soon !
Nice!
Thanks man!
Amazing work!!!! Thanks
Great stuff!
Nice bro 😊
Very nice design! Any issues with HF interference affecting the arduino?
Can I connect the existing Z-axis stepper motor of the CNC to the THC system instead of adding another motor for the THC?
You're a god amongst men. Does this have touch-off capabilities?
Hello, what program does your THC run on computer?
Your very pointed about using the nx4832t035 screen - looking at the ad in Amazon - the next 4 T series displays have all the same attributes up to the 7 inch model. I need a bit bigger screen then the 3.5 inch display.
No you can use whatever but If you want to use my tft firmware file then you have to use that screen. Also you may have to redesign the box.
Hello congratulation, friend how you control filter noise in your arduino THC ?
👏🏻
Pretty neat... Problem is, it appears that the Arduino code does not have the Move (b0 and b2), Min (b4 and b5) and Max (b6 and b7) values defined. Users who attempt to use any of the Settings screens will find those buttons do absolutely nothing. Any plans to update the code so the Settings pages actually work?
Don't count on it!
Will this work on the DDCSV3.1 controller?
Just a thought could you take your existing code and run in it through Chatgpt and make it for use across multiple platforms . Say raspberry pi zero ?
nice
Hi
thanks for posting the THC construction project, I have ordered the parts from Amazon and will be building it soon. I have built a few Plasma CNC tables and have a question about your THC connection to the CNC controller. I see you use a separate driver for the Z axis for the THC. The questions I have is how are you paralleling the drive signals for the Z. The G-code is normally driving the Z and it seems your setup is to drive the Z only under THC control.
The THC units I have used before sent the up and down signals to the BOB which then operated the Z using the same path as the G-code commands for the Z axis movements.
Thanks for you time

Yeah it's a standalone controller so it's not meant to hook up to any mainboard. But it actually produces single step up and down signals so the main board if it can collect 5 volt up and down signals it can do the conversion if the controller smart enough. My board was not hence making this standalone... So my table has two z axiss one dedicated for the torch height controller only...
@@CountryAireDesign thanks I think I will try 2 small relay packages (one up and one down) to see if I can hook them to the BOB to operate as a combined drive unit. They would hook to the THC inputs on the BOB.I tried to send a message on your web site but it stated an error??
I need to buy you a cup of coffee Thanks for the quick reply
Merry Christmas
@@bigirish4886 have you looked closer into using the z-axis?
@@EkholmAndreasThis unit is like other in that it does control the Z axis when cutting. The problem here is the unit does not work due to not being able to enter setting for the control. Project is incomplete, will not work
@@CountryAireDesign There is an arduino hat with 4 relays which I use to toggle between THC and the cnc driver board.
hello my friend, one last question would explain how it works better because if the z axis has to go down to touch the plate and then fire the torch how to connect this driver to the stepper motor since it is already connected to a driver that does this move that I did not understand, the step and dir will be connected to the same driver that I have already connected to an arduino with the grbl firmware could help me with this information
No this is a standalone type of THC, so you need a small actuator as another small z axis. So my machine has 2 z axises... Also, the Arduino generates up and down step signals so if you can pipe that in to your main board somehow that might work... I couldn't figure out so have 2 z axises.
I use a breakout board with my plasma cnc, could I use this with my breakout board? Does your motor driver do the same as my breakout board does?
Arduino puts out 5v logic level step and direction signals but the Enable is just a single 1 time single at startup for the tmc2160 so other drivers are not likely to work without some code changes to the Arduino. Code is available so feel free to change it to meet your needs.
Hello friend. Will this THC work with GRBL and it's GCode senders? Nice work. Thanks.
kinda of, watch my new video: th-cam.com/video/WTnTKMmFKe8/w-d-xo.html the info about this is at the end after the demo. but watch the whole thing!
Any changes I have to make for a NEMA17 motor?
Back again I have loaded the Uno and the SD for the display, have not connected them together yet. Question is how is the info that is shown on the display (delay, voltage, and other) loaded on to the display, is it done via the touch screen or loaded to the SD card?
Yes loaded from the SD card. Pretty easy just put in the SD card in while it's powered down then power it up it'll load from the SD card then power it down and pull the card and continue using without the card.
@@CountryAireDesign Thanks again
Did you use raw arc voltage initially? Can this setup handle raw voltage, assuming the necessary voltage wiring precautions?
Nope, this thc needs a Arc voltage should be divided 50:1 stepdown. I cannot offer instructions on how to modify your plasma cutter or add a circuit to my design. You're welcome to try to figure something out but I've said this to others... All I can say is be fucking careful those voltages can kill!
@@CountryAireDesign Thank you for your reply ! And thank you for sharing this with everyone.
@@CountryAireDesign Especially, clingy DC voltage

Hi, I wish to know if you have instalation instruction like wiring ?
Good Idea, I made a wiring schematic and added it to my build info on Openbuilds. Here Check out the details : openbuilds.com/builds/standalone-torch-height-controller-for-cnc-plasma-cutting.9571/
Hello Mr! Can you help me with what nextion display you use? Nextion NX4832T035 3.5 ENHANCED SERIES? It has a lot of RAM (8192 Byte) and free file ~ 6500Byte)
Dont get the enhanced one. My file only works with this version: www.amazon.com/gp/product/B07916QBDZ I think you are confusing RAM with Flash memory.
@@CountryAireDesign Ok! Thank You! Don't have a good description for voltage distribution construction?
I understand that this is a standalone THC, it can work with GRBL. How much does your device cost?
Setup requires the Ardunio IDE but no computer need to run this... Might work with GRBL but I don't know how to do that. Development required forsure. Cost for me was 50 or 70 for the mega version US + an Actuator I already had. Even with buying the actuator new its still cheaper then the next best available thc out there. This project is still new and any changes will require a lot of development and testing.
Well I have installed the SD and info loaded to the display, still no settings data on the display.
Can only change the set voltage with the slider, the THC GUI is dated 10/17/2020. The display shows exactly what I see in Nextion Editor before saving to the SD card, is there another file that was not on Github that has the settings??
dang, your right man. Oops... I've uploaded a new display firmware to the Github go and grab that. Let me know if you see the settings data!
@@CountryAireDesign thank you sir gives me something to do, getting much closer to the finish. Printed out the cabinet looks great. Longest print joe I have done to date. Thumbs up
Hi! I built a desktop version, Arduino Uno MKS Board + Stepper motor + TJC (Nextion clone) 3.5 "HMI LCD. Bad without a capacitor, and works late with a 1qf capacitor. What could be the problem. I press the display in the settings, but the arduino responds late .
I linked the video about my error.
My other question is how to use Arduino Nano or Mega? What do I need to set in the program file to work?
th-cam.com/video/AIQtzo7KWwg/w-d-xo.html
Nice build and video, seems like the Nextion signals to the Arduino are not getting thru. 2 main reasons for this the serial connection has noise or bad connections and the other reason is in the Arduino sketch... it has to check for plasma voltages then it checks for Nextion Input... but the Arduino can't do both at the same time and its slow. It is a good I idea to hit the button faster to catch the Arduino reading the Nextion Input. I believe upgrading to an Arduino mega would solve this issue because it has to do with processing speed but the mega has issues porting the EEPROM Library. I've been working on that but without much success. As a Workaround for now, you can set the Default Values in the setup section and just flash them to the Arduino.
@@CountryAireDesign Hi! After 1 year, I rebuilt the plasma cutting machine with a working area of 2000mmx1000mm. I added 3 outputs to the controller you made for Mach3, so now there is THC up, THC down and THC reason signal for MACH3. I had a problem, the analog input was "floating". The capacitor does not attenuate. What else can you think is done to keep it from floating?
Where can I find the wiring diagram for the ethernet plugs? I have everything completed except for those 2 plugs. I got the type of plugs you have for the in and out just do t know how to wire them. Any help to point t me in the right direction for schematics on this would be appreciated.
There is none because it changed by other hardware you're running... The short answer is it's color-coded to an ethernet cable as long as the cable is not so cheap that it doesn't have the colored wires in it. Lookup a cat5 wiring diagram on the old googles and a multimeter in continuity mode (beep-beep) helps. Also, use multi-stranded cables where a lot of movement is required.
@@CountryAireDesign thank you for answering. I figured it out last night. I did the test with the stepper motor last night but am having one problem. It only moves one direction not 2. Gonna double check all connections today and figure it out Thank you for responding though I really appreciate it.
What about the AC component which rounds at 15000 volts at 2MHz (ignition), does the capacitor is enough for that?
Does someone know how to protect the microcontroller for that AC signal?
2Mhz seem like HF ignition, you should use plasma machine with blow back ignition... that will save you from headache caused by interference.
Hi! which model of plasma cutter do you use?
Everlast Powerplasma 102i
@@CountryAireDesign Thank you!
Do you make and sell the enclosure?
Good question. Nope gotta make your own or have them made. I printed mine but the parts don't have to be 3d printed. Design Files available on my Openbuilds build.
Hello! I find your project amazing, and I am building it right now. Got all the components, connected . Arduino seems ok, but I can't get the code to work on the TFT. I copied THC GUI V1.0.1.tft on the SD, but I get the message "file version is too low" . I hope you can help, I have been stucked on this several days.
Don't count on it!!
@@DogSerious Has the guy disapeared? can you help if you have been interrested in the project?
@@fabricegabrini7776 The problem with TFT's is that they all have different drivers, the SD cards have to be a certain GB size (either 2 or 4GB)with a certain type of format, and file type like RAW, try increasing the size of the RAW file.
I see that the "50:1 Plasma -" is connected to the Arduino board's GND and that the "50:1 Plasma +" is directly connected to an analog input pin with a smoothing capacitor. Isn't an opto isolation circuit needed?
Yep an opto isolation circuit would be a great upgrade to this design. It wasn't needed for my plasma cutter but I know all plasma cutters are not created equal. Problem is for me, I don't know the first thing about opto isolating circuit design. And I wanted to make this design with off-the-shelf parts that don't require custom circuits. So community input is the most definitely encouraged here 😉
@@CountryAireDesign Great that you don't need one. For the Hypertherm 45XP, I based the voltage divider circuit on forum.allaboutcircuits.com/attachments/30-jpg.93867/. I skipped the differential amplifier though and used two analog inputs instead.
I assume that you can do the same thing with a raspi?
I don't see why not

👍👍👍👍👍👍👍👍👍👍👍👍👍👍
I really confused ,, in this video you made thc ,is this dynamic thc ,
And how to connect to mach3 interface board ,,, ???
It's a Standalone THC system that has an onboard driver to run its own stepper actuator. No need to talk to Mach3 or whatever speed we are going these days 🙃
@@CountryAireDesign 👍. And I had another dought , I using (GB KORE ARC Air Plasma Cutting Machine (CUT40)
In this how can I find arc voltage divider ,, sorry for asking dought 😉
@@suriyabala5860 no idea for that machine but you'll definitely need something that divides it down to less than 5 volts or you might fry the Arduino. Playing with arc voltage is no joke be careful!
@@CountryAireDesign thanks you for your reply 🙏
Sir I don't have touch display , but I have lcd display in that how to make standalone THC pls give idea
The important part of the Nextion display is to have onboard processing of ui events. So I don't recommend using another lcd because that puts way more work on the Arduino to handle ui events and would slow down the position calculation. If no Nextion... It would be best to use no lcd and just preset everything in the Arduino sketch...
@@CountryAireDesign thanks for replay ,, I got another idea to make
In two relay+ dc 12 v motor to make THC and simple arudino program , I will try , if it's work , I will share you conclusion
Would you consider building one for me if not do you know someone who would
Hi sir.. how to made voltage divider for plasma?
I don't know, My plasma cutter has one build-in. I don't want to recommend something because that is a High Voltage system and I have little experience with high voltage electronics. Please be careful!
@@CountryAireDesign thank you so much..🙏
Hello sir ... Can I replace the lcd with another
Not a good idea because the nextion processes it's own user interface. Another screen might need the Arduino to do that and slow down the positioning logic. Best to go no screen at all and hard code setting directly to the Arduino.
@@CountryAireDesign Can you use the nextion nx3224t024?
@@yunantoophen sure I think the Arduino sketch will be fine no need to change that but you can't load my user interface onto that screen... You have to recreate your own using the nextion editor.
hello my friend how are you I'm here at home trying to set up a thc with your files i am optimistic to use and be more successful i noticed that your arduino uno sketch is not working when i compile it appears an error would have you check this because I have an arduino uno here and not a mega arduino your arduino mega file works without any more but unfortunately I only have one arduino here to test, and I'm editing the display file because mine here is 320x240 but I'm almost finishing to connect everything and start the tests, if you can help with the file repair for the arduino uno i will be very happy, congratulations once again for your project my name is marcio and i'm here from brazil
Cool, yea I just posted a sketch for Arduino Mega2560 to the gitgub. Please post all issues with detailed information to the open builds discussion forum so everyone can learn from it. Link in the description.
привет, мне понравился ваш проект ,но он дорогой в компонентах , можно ли его сделать более дешевым и доступным ?
Hi, I like your project, but it is expensive in components, whether it can be done cheaper and more accessible?
Good Luck! This has all the same features and is 1/6 the cost of an off the shelf THC. Only thing you can do is cut features to save on cost... Just skip the UI features and hard code the settings into the Arduino Sketch... but really this is the cheapest THC I know of
@@CountryAireDesign ПРО ПОлКУ Я НЕ ПОНЯЛ . монитор стоит на али экпресс больше 38 $ .
можно ли выложить с простыми lcd мониторами прошивку и схему ? будет ли такой проект ? конечно что бы был автономным контроллером с функцией контроллера высоты плазмы .
I do not understand about the ass. Monitor stands on Ali ekpress more than $ 38.
whether you can put a simple LCD monitor firmware and circuitry? whether such a project? Of course that would be a stand-alone controller with the controller function of the height of the plasma
а вот схема делителя напряжения доступна?but voltage divider circuit is available?
@@user-uv7oe9nj9u Nope, my Plasma Cutter has that built-in so you'll need to source that yourself.
Told us like 4 times in the first 2 minutes it was “completely open source” AND people are free to modify it to their liking. Repeated yourself 7 times in under 4 minutes. All of it is already implied by the existence of the video.
