Here's the full plasma build series:
• CNC Plasma Build (Full)
Just the LinuxCNC stuff, including how I did the HAL for everything I mentioned here:
• LinuxCNC Guides
Additional LinuxCNC documents of mine, and links to other people's video and/or files can be found on my GitHub project here:

Great plan on the air supply pumping the water into the cutting basin
just weld up a water table. Check out Stefan Cymbaluk channel for good ideas. He uses Linuxcnc as well, and using the Price THC(he has also used cheaper proma on some builds). His videos focus more on the table build and not much detail on the software. I'm building a virtual copy of his 4x4 "heavy duty" table, plus I'm using Linuxcnc, so your videos are very helpful, especially since I'm a linux noob as well.
Nevermind on the THC, I saw your next vids where you make your own. Nice work.
Yeah, making that THC was a pain in the ass, but at least it was a learning experience. Hahahah.
I finally caved and got a (very) basic oscilloscope earlier this week, so now I hope to go back and re-evaluate how I did that, see if I can make it more robust, and if so, offer a parts kit, or least a link to where you can order a professional PCB and the BOM parts.
This video's pretty old now, but I still haven't gotten around to doing the full water table. Mostly tied up in the THC project and all the HAL videos that came after. It's the next thing slated for an upgrade though. Welding one would work, but I dunno. Think I might try the fiberglass again. Redeem myself after that last attempt. #YOLO
Hadn't seen Stefan Cymbaluk's stuff before. Thanks for pointing it out to me.
@@swolebro I would also check out the making stuff videos he did a plasma table a while back and is doing just a cnc spindle/router table now and they are fun to watch. I am working on my own CNC plasma table based on both your videos, Steve Cymbaluk's, and the Making Stuff videos. I am taking pieces from all your guys builds and then adding my own flavor to it. I will post RUclips videos someday and link you to them. Plus I will mention you guys for sure to make sure you get the credit you deserve. Also then try to figure out github someday. I for one would not have taken this awesome project on if I had not had your guys videos to watch. (I have built some of my own 3d printers and modified a broken one in recent years, so playing with electronics and xyz tables are fun) I also wanted to add I think the Bender tool you made is awesome. I am going to have to do that when I get my table done; pure genius in my opinion. I am struggling with the THC myself though. I am using a harbor freight plasma so I need to design and build a Voltage divider that will be robust and handle all the dc voltage noise from the constant 80-140 volts to the every once in a while spikes of up to 300 volts. Or do I purchase one of those 200-300 dollar kits that has both the voltage divider and thc controller that just inputs to linix-cnc on amazon or Ebay. (its a tough pill to swallow when I know the parts to make the boards is like 20 bucks) I have the knowledge but not the 300 volt power supply and the oscilloscope to test out the voltage divider on as I build it as well so that also comes into play. So I'm rambling now sorry. But in the electronics stage that is where I am at in my research. Thanks again for your videos and posts on HAL!
@@blue95stang1 Not sure if you've seen, but later in the series I did manage to fabricobble an Arduino based THC. I wouldn't call it a "finished product" by any stretch of the imagination, and I spent way more than $300 of time building it, but it was a learning experience. There's a 1hr video for the board and another one for the code.
If you want to try your hand at it, you get yourself a DSO138 oscilloscope for about $30 just for messing around. It's far from professional, but it lets you get a decent visual. I got another recent video on using that to reverse engineer some treadmill controllers.
If you've got any experience with Arduino, another option would be to buy a THCAD from Mesa (they come in 0-300V and 0-10V styles), and then use an Arduino as a frequency counter/encoder to turn that into a dumb up/down signal. That just saves you from dropping the extra $200 on a Mesa controller board just now (while the THCAD is only about $70). Though really, a Mesa stepper board + THCAD still costs less than a $300 Proma THC, and gives you a lot more features.
Good luck, have fun, and all that shit.
@swolebro - dude I have been watching all your videos over and over since you made them. ( maybe 20 ish times lol) I think I can replicate your thc no problem. I am just wondering about the voltage divider. I know what it takes to do the 50:1 with the cement 5 watt resistors. But in order to handle the noise I don’t know without testing with a scope what chokes to use to get as straight a line as possible. I will check out your recommendations but I’m a 15 dollar parallel port breakout board all day long. I have time, more abundant then cash. You’ll understand that real well someday if you ever get married and have kids.
