Hi, does your plasma cutter generate a lot of dust? If so is extraction etc required?

Just Curious..Can this module act like a MPPT charge controller for solar application. That is If it is programmed properly for Maximum power point tracking..

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?

At least it was an educational experience reverse engineering. However Allen Bradley Powerflex 4 VFDs (as an example) can be had dirt cheap used, without having to decode and hack on an Arduino. One model can convert 120v single phase to 208V 3 phase and would be more user friendly for the lathe. It even has a speed potentiometer on the front panel that can be used or bypassed. With some other add-on items like a small HMI screen and a Remote I/O or Ethernet connection, you could set up a simple custom touch screen interface to control it. Your method might be more fun from a raw engineering perspective, and I can respect that.

The x & y axes. Did you design the gantries, or did you get the design from somewhere else. I'm asking because I to would like to build a plasma table. The table is easy, but the stepper motor mounts to the tubing is a bit harder. If there are any plans, I'd like to be able to get them if possible. Great vids.

This video and accompanying notes earned you a sub and a like. Thank you for your attention to detail, and especially all the links in the notes.

When i type in "tree it says bash: tree: command not found" What am i doing wrong?

I salvaged the same fry cutter from a dumpster of a pub that was being reno'd. I didn't see the blade or pushing block so I'll have to get those separately if I want to refurbish it for the original purpose. I guess I was fortunate that none of the set screws nor bolts were rusted in mine but I was having a helluva time trying to get the end with the set screws to move so I went searching for a teardown video to ensure I wasn't gonna destroy this if I just increased the force being applied so thanks for the video! An alternative use for this I'm considering is as a level slide rail for sharpening. It could be used to square up the blade from a vintage Stanley hand plane I got at a garage sale for a steal as well as act as a guide for setting a specific angle to sharpen any blade.

I have different drivers for each axis

Вставляем в чашу предмет,чтоб зафиксировать ножи и крутим звездочку с обратной стороны по часовой стрелке.Когда гайка ослабнет,зажимаем ее плоскагубцами и выкручиваем😊

Is there a reason this couldn't be incorporated into the bottom of the ridgid shopvac? That way there would be less stuff to lug around yet it would keep the filter clean? (Note I also left this question on the Thingiverse site)

Great series you've got the skill to teach. Please keep going man!

I seen someone load gcode on flash drive then to arduino but I have no idea how it was done I’m guessing GRBL

Down the rabbit hole I go I got motors power drivers arduino freecad and now I’m lost any advice to go from freecad to arduino also i was under the impression you can have usb to arduino and go

😂 they put the wrong plugs on for the wrong connection. I wonder if you can just swap the plugs and if it will still fit.

I’ve been watching your videos on linuxcnc since I am building my own… but after seeing this video I’m subscribing 😂

Fantastic work here

Hey I just discovered this. Thanks a lot to the shoutout! Subscribed! EXCELLENT work here, I really appreciate the content.

Good evening, wondering if you could do a tutorial on creating a cut fill in sheetcam or fusion 360 and imported into Lennox CNC. I seem to be struggling with this, even with the Lennox post processing. Thanks Rob

Fantastic video. I learned a lot. Thank you!

First class video. I now have a pile of neatly wrapped inner tubes in front of me👍

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.

what need config home SW working, bush button home X and go to X left at beam . my machine go to left home SW but then go to back right and not stop move, what is wrong.

Lots of chatter and coughing… edit is your friend.

forum not help any to dual Y axis config and working, i try many answers at forum but any not help, not working newer only come lot lot more errors and change many different code to config ini file but not working. forum not have sure egualice, all help has totally wrong and not newer working.

linuxcnc documentat not have any good no tell how you use dual Y axis , i has try million time make dual Y motor working but only one working. XYZA config use second Y motor only angle run, not same than Y1, not possiple use. and then has lot error i add joint 2 to Y axis, copy joint 1 Y axis to joint 2 axis need run sametime, ok sometime working but lot errors, all homing not working, Y axis go to home not working ,not have aktive to display, how can go home first, not can run cnc if not can go home all axis first. ewery homing axis start lot errors.

I spent 220 dollars on a THC controller for my Hypertherm.

Best I’ve seen so far. Especially that “tail” section. Now to rewrap my tubes.

you're a hero!

Thanks so much for this,. I have the longs kit and there is soooo little info on this. Really appreciate it!

thank you so much for such a good linuxcnc tutorial guide I have learnt alot and you put things in a way i can understand thank you, will you ever be making some more tutorials with current linuxcnc or any other parts of linuxcnc?

Fantastic video, thanks very much. Bit off topic but I am always saddened when I see such a great educational video have only 99 likes after 3 years, whereas some meaningless video about absolute rubbish gets millions of likes. I made an educational video on inline boring (machining stuff) and I think most of the world, except for a few, were completely bored by it LOL. Well, I'm one of the few that thinks yours are awesome.

I have Power Step PSD5042-2P drives. I have a signal sequence timing chart. I’m not sure how to convert that to Step Time, Step Space, Direction Hold, and Direction Setup. Can you help me?

Can i use the THC on my Arduino CNC Shield?

Nice! Took me 2 views to hear about your sleeping arrangements...

I can not thank you enough for this video man . this is what i was looking for . Thanks man

I should have watched your video before I bought gauze and put it all over 😢 it hurt so much basically pealing of all the skin that formed

Again, thanks for doing this it really pushes me forward much faster than if I figure it out all myself

Thanks for these videos, they are right where I'm at in trying to get started and really speed up the process.

my first time i use linuxcnc, debian 10 preem rt. and i not understand motors working but how can make E-stop and probe working i has open hall- meter but not newer come true/false i test whit NC button to pin 10 is E stop and pin 15 probe. and step conf wizard have pins setting ok. motors move, XYYZ have wizaerd make XYZA config. end stop pin 10 and probe pin 15. why hall meter not show newer true/false, what need do next can make working. brealout board is connect wires gnd, probe, and gnd to e-stop, and buttons have NC. help please. i not understand good english.this is first time i use linux and linuxcnc. last night can make motors first time run both Y axist run, wizard make A axis pins same setting what have Y axis setting. but why e⏹ stop button not working or probe why hall meter not show if button is on or off.what need do ? help please.

what motor setting need use, today i has make stepper wizard my motors, max has only 30mm/S velocity, what normal used. and why not can use MY-MILL move motors. i has setting now wizard motor tuning and test, move ok but if start my-mill after setting motors not move, same hall meter not show E-stop or probe true/false. has connecter to breadboard 2 button and wired, e-stop pin 10 and probe pin 15 but not working true/false at hall.meter. what need do next. my-mill display not have active, see only e-stop have bushed left up corner. debian 10 preem-rt have and linuxcnc only paraller port, config need be ok, but not sure, jitter i not undertand anythink test but have alltime different. nema 23 2Nm motors. hobby budget not can buy biggest motors, 2Nm 3A motors cost 50$/4axis. biggest cost 100 or more $/axis not can buy. table size 1000x800x200mm

This is one of the best HAL tutorials i’ve encountered

Hey just starting my Linuxcnc journey what is your m3 command ?

Hi! I just made your sketch! It works very well, but it does not give the commands to MACH3. I suppose that is a Mach3 problem, the command appears in MACH3 in "Diagnostics" menu, but there have no reaction in axis z as response to these commands (UP/DOWN). Have You any ideea how to set up MACH3? Or maybe another user that follow your sketch have any idea, how to do the right way? Thanks in advance!

i can give you some useful information how to take the blade out. the tooth side you can use a 10 or 11 mm ring spannerthat fits perfectly. for the nut you can go with a grinder and cutting disc and cut gently a cut for a big screw driver that will work , good luck guys

Flexible (many thin wires) silicone-insulated wires helped a lot. 13 AWG (12 AWG did not fit in the big holes on the small switch board), but I had to solder the wires for the switch to the pads on the board. Btw have you tired to switch off/adjust the speed of the fan on the case? It spins up even when there is no load.

Nice.

Wow this is awesome, there is so little info about this on internet. Thank you. Liked and subscribed.

Great, not another CHINA-MAGA sheep. 😞

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!
