46:40 NB the Nano has 5V and 3.3V LDOs onboard, so there's no need for that additional LM317.

Excellent work. Long live the open source.
@seanmcdonald656
Great video thanks for the very good explanation on how the ride hight works
@LinkerKlinker
Nice job I am going to use a Attiny in place of the Arduino and move the Arduino to behind the optoisolators so I can have the Arduino connected to usb as well.
@body32003
Thanks for sharing your work with us. Do i have to apply your thcud mod to qtplasmac component or it already has it. Mine works perfectly fine for about 20 seconds and then dive down i suspect it's due to emi interference but i need to be sure about the hal stuff first
@tahaparkar9526
Your code is not working,its not required voltage on 7 segment display,it shows 11.7 after change A0 voltage its not decreasing nor increasing
@plb53apr06
Hi, watched your video. On your Voltage Reference point. A better way to do that is with a Voltage Reference IC. Fewer parts, they don't require adjustment and are reasonably accurate at the "entry" level. For 5V MCUs, I like 4.096V refs as each count is 1 mV. Just adjust your divider so full scale is 4.096 volts.

Thanks for posting this, I've been thinking about diy thc's quite a bit lately, if I ever end up building one, this will be very helpful. I've got a question about the input voltage sample from the plasma, would a 5.1v zener diode between the input voltage and ground provide adequate over voltage protection? Or, would that introduce a whole new set problems?
@CeNuVezi
On schematics , if u use 12v powering arduino u will burn ic . This is a mistake , u have to use ony 5 max 5.5 v for powering arduino .
@sennabullet
SUPER informative! Thank you VERY much for sharing your knowledge and experience on the THC.
@утка-я4л
Привет друг. Спасибо за твою работу. мне очень понравилось и я хочу сделать такую схему. Скажи пожалуйста, ты оставил ее такую как есть или что-то менял ?

How would I change the code so the arduino outputs a step and direction signal to control a stepper motor driver? I'm very new to doing any actual programming other than changing values I can easily identify and reassigning pins. I use grbl to control my DIY plasma table. Works good if metal is flat, or I use a drag tip and floating head. I have another arduino based THC designed by another youtuber that works, but it too uses a separate arduino to control Z axis. It was designed as a standalone unit which I used diodes to allow my grbl to control Z until torch fires, then the THC takes over the Z axis. Your design is more of what I would like, turn a knob to set voltage instead of using a touch screen that has response issues at times. Wish I knew enough to integrate the grbl code and THC code into one and run it on an Arduino Mega 2560. I'm running grbl on a Mega with 3 TB6600 drivers off a breakout board shield for the mega. I don't have a good enough understanding of the code nor the time to really dedicate to learning it any time soon.
@Lesiu_u
35:45 Well its not really works like this. If you are powering your arduino with VIN pin with voltage between 6.2 and 18V (there is 1.2V drop on regulator), that this voltages goes to 5V linear voltage regulator, something like LM7805. So no matter if you powering up your arduino with 12V by VIN, or directly with 5V by 5V pin, you getting Atmega328 (core of arduino) powered with 5V, so you still can read up to 5.5V safety. It is metioned, that you can read Vcc + 0.5V, beacuse you not really must power arduino by 5V. It can be 3.3V or any other voltage tolerated by Atmega328, however 5V is recomended beacuse of other components on the board.
@alexandrugroza839
Hy, did this setup work well on long term ? i guess you have used it a few times since the video was posted, if it does work as intended, why are commercial THC modules like Proma compact soo expensive compared to this setup which is pretty simple and cheap, does they offer something extra ? The input voltage from plasma, if it doesn't have the output divider, can be taken from the ground clamp + torch wire and step down ? also in Proma THC which voltage needs to be input, divided or directly high V. Ps very nice explanation in the video!
@tutorialjowo2537
can it be connected to grbl?
@ajcreativemakassar
THANK YOU FOR YOUR PROJECT...YOU HAVE SCHEMATIC VOLTAGE DEVIDE?
@rezafaisal1244
Can i use the THC on my Arduino CNC Shield?
@richardfalcos
Hi, Swolebro, very good explanation, please ask me a question: in your project, does the plasma power supply need to have a voltage divider?
@CeNuVezi
Can u give me the hal , and ini file for parport , i have a plasma , and having issue with config linux cnc , now i use qtplasmac , and are a loot of configs that i dont get thme how they are working . Thanks .
