Thanks for the video! I'm going to build similar CNC plasma table in future (once I get a bigger shop), so this was really useful!

Ok thanks for all your help

Great stuff thanks for sharing

very help full thank you

thank you so much for the video, ''its gives me an idea, ''

I also noticed the blue torch and the label shaking. You can use a heavier gantry and torch mount and don't be afraid to make it move 65lb dumbbell back and forth with stability.

I like a lot the way you did your plasma table , very simple and stable. Could you please chare the file of the box for thc

Hi Bob, I have to say, you really have a broad spectrum of knowledge at your disposal. As well as the fact that you had the Cajones' to make a video that is insightful as well as instructive. Hats off to you! Oh, I do occasionally get a bit nervous about your long hair around all the moving parts. How do you work around that?

Your torch is shaking in your mount no doubt causing irregularities in your cut. Try to secure it a little better. Your edges will come out better.

Good stuff brother!

Great video !

Dang. Would of been nice to see the wiring process on the THC. Im using an Adrenio Board with a 5v relay

I have been messing around with a diy plasma table I bought for 5800.00 and it has the THC already but it always eats consumables because it touches the work and over heats. The preset for the THC have been at 120V and I look forward to dropping them down to see if this helps. Thanks for the video.

Amigo, instalei uma tocha plasma na minha cnc e ela recebeu interferência quando acionei a tocha e isso fez com que a cnc parasse. Voce sabe me falar o que pode ser esse problema?

Hi i was wondering if you had an extra cover like the one you printed out for the THC. i would like to buy one if you do.

Hi! Friend you can made a video how calibrate the thc!! Please

I love all your videos. what size wire did you use for + and - on the Proma?

Hello I’m just wondering where you wired in the torch height controller into the breakout board? Great videos thank you.

Why is it sparking so much above surface? Was a consumable problem or recurrent issues?

Hey Bob just a a tip. consumables for a plasma cutters are rated in amps 40 amps 60 amps and so on. The higher the amps the bigger the orifice. you need to match your amps to what your consumables are rated for cutting on low amps with a big tip will produce crap cuts and burn up tips a lot faster. I don't have a HF plasma so I can't say what they come with or sell for them but they should be marked but figuring out what size you got and not go to far under that amperage might help improve your results and make tips last longer

is there something you have to do to work in program mode ?

Wonder is there is a fiber laser DIY option?

Good job Bob. Yep, the door slider's got to go. Ciao, Marco.

Hello sir, i also made the cnc plasma machine without THC or z-axis. When i doing any job on the cnc is plasma torch is always on. When i doing holes in metal sheet is holes are done but the path is also cut. Pl's help me. The THC is needed to torch on/off or failure of sheetcam design when i made the design.

@making stuff Im currently working on a build similiar to yours but Im using Mach 3. The 150 THC uses 3 Input pins on the Hobby CNC Pro 4 Axis... did you eliminate some of your limit switches?

friend do you use arduino? you know if I can put that thc on my arduino?

Ive been watching youtubes on how to make THC's but that talk about voltage dividers to reduce the voltage so the low voltage boards can handle the voltage while reading the highs and lows. Does your plasma cutter have a voltage divider or is it that a proma does not need to read from a voltage divider. Hope you understand what I'm trying to ask.

Are you using an Ethernet smooth stepper in conbination with your thc

Do you sell those 3d printed little boxes ?

Hello man, I am building a 2x2 mt plasma CNC, I have nema 23 motors, DM 542 drivers, a Mach3 Usb 5 Axis 100khz Cnc Controller Card, I dont have the height control, which is not expensive and easy to get, can you suggest one? You have plans to help me with its construction, I will thank you, greetings from Peru.

Congratulations. I have to figure out how to wire mine. Because I use the same controller for my router as I will for my plasma it will be a little more complicated. Maybe I can use a different pin for Z with the plasma setup...hmmmm.

I can't tell if THC installed intended as click bait but it worked on me.

I just got my cnc plasma machine from china, as I tried to get it up for running there is problem that I have and I hope someone can help. when I tried to cut a piece of metal, it doesn't start, it keep popes up message box say " ARC BREAK ALARM" I tried it manually the arc work. sometime the machine runs but not arc, doesn't cut at all. any idea work could be wrong? I was told be the guy who I bought it from I need to clamp it on the material not on the bed, and I need to adjust the voltage higher. Is that right? Anything will help. Thanks

Which model mach3 controllers use

Is your switch wired normal open r close thanks Dewayne

I'm a bit late but have you considered using an ohmic sensor instead of a floating head?

got a question about the sheet metal your using what is the price roughly per sheet?

would a better quality plasma cutter such as a hypertherm give a cleaner cut

hello, i would like to ask you if you have tried to cut under water...

Which CNC controller board are you using to control the stepper motor drivers?

What's the cut out size for the Proma display to stick through the black box?

CAN U TELL WHERE I CAN GET THIS HEIGHT CONTROLLER , THE LINK IN THE DESCRIPTION DOESNT HAVE THIS ANYMORE ,

Will this THC work with the Hypertherm Powermax 45 XP?

It seems that your cutting speed is too slow, try increase speed by double, you will get more dust but finish will be much nicer almost without dross. Or lower amperage, it looks very thin sheet metal.

if i may ask.... where did you order the Proma THC......... i ordered mine from ebay and i have been waiting for months......im guessing i was scammed... still waiting though. but your video inspired me to order again but i dont want to be fooled the second time. nice vid

Whats the benefit of this? just for sheet metal that is not perfectly flat?

Really cool video. I want to build one now lol. That floating z looks a bit wiggly. Here's a slightly better 3d printed one you might like.

Hi, I want to add proma thc 150 to my newly built plasma table.... How is your experience working with it till now. I'm at a point to buy proma ($300) on ebay or others less priced than proma....... Your advise would be really counted on! Thanks

Hi... where did you purchase the proma controller from? I am having a difficult time locating it.

Bob, i think you missunderstand the concept how a THC works. When you showed those test cuts you don't have to set different volts. You have to watch Proma what volts it shows at a given feedrate at specified amps.(of course delay time has to be set maximum so you can watch it without before Proma starts to control and volts varies. By the way that feed is just way too slow.

Cant you get a straight torch head? So that you dont have to mount that in such awkward angle?

How much did that cost to build that table

Will this work with Mach 3?

THC mach 3 breakout board connection plzzz

Please add lighting to your work area. It is hard to see what you are describing.

How about metal sensor for replace the THC?

I'm all in for tech solutions, however sometimes it seems like stepping back and rethinking the problem helps. Here, the problem is your metal is warping due to heat. Instead of adjust the head with electronics/sensing, etc, why not adjust the material being cut? Off the cuff, it would seem like it might be possible to put 2-3 legs spaced 2-3 inches away from and around the cutting head with captive bearing balls for heads. Bottom of the ball would be zero'd against the metal pressed against the table before starting. Then your cutting head would be raised above that level to the height it needs to be. Every time you start a cut, the head lowers, the ball bearing faced legs push the sheet metal to table, and the cutting head is now at the proper height against nominally flat metal. A drawback might be the balls rolling over previously cut material, however I imagine some sort of compressed spring on the top of each leg would be able to provide just enough 'give'. I'd like to build one of these, so will try it, and then probably end up with a torch height controller anyways.... But then, what about making the table an electromagnet, and pulling the material against it?

Your machine had more vibration,this is the problem Sr

I don't personally need no thc in my life. Drugs are bad mkaaaay!

No, it won't. learning WTF you are doing instead of throwing money down a hole will fix the problem
