  1. Click bait? So when I got quoted for a 20k table the plasma and compressor wasn't included. Its very dependent on your needs on which plasma and compressor to get. It's still a plasma CNC as it's modified to do so. However I only payed £235 for my plasma and my compressor was only £100. So still a good deal in my opinion and I hope the contents of this video has value to you. I recommend Veritasiums video on click bait if you're not comfortable with my video. All the very best. Cheers J

  2. Will this work with other laser machines. I was going to buy an atomstack a5 or a5 pro to get started. Also the a5 only has a travel speed of just over 4000mm min is this an issue when using a plasma cutter. The a5 pro has 10,000 so I was thinking of getting that instead

  3. if you use cambam(free software) you can scale your workplace smaller than your part which means you could cut a part and once your gantry is to small to cut anymore, just scoot the gantry over and tell the software where the cut begins now and normally after a few tries you should be able to cut designs into 10ft sheets

  4. Hi i am doing the same project but i have a problem with the relay. I have a PWM voltage of 1.7V and it does not activate the relay. What is your control voltage on the white wire?

  5. Dross on the bottom means you're moving too slow, speed it up! Meanwhile, top dross means too fast.
    for 3mm steel, my best speed quality settings is 50 amps, 2540mm/min. ensure the torch begins with a height of ~1.5mm above the material, and maintain voltage from there.

    Clean material surface helps a lot too!

  6. Sir, i am just sitting here after watching your video twice, and am gob-smacked at the simplicity and ingenuity of how you put together a DIY masterpiece that anyone would love to have. Now I know the price will vary as to where you are and where you shop, but who cares! The money saved from not having to purchase commercially far outweighs the little white lie, (but isnt) that you used to get people to watch. Thank you so much and if you ever start a design page for your work, let us know.


  7. Been wanting to build a cnc plasma cutter after working for diode lasers. Have a spare frame so all good. Think this would be worth it to be able to make the parts that I need to build one. Thanks for the video. Really appreciate your detailed video. 🙂

  8. this is so rad! i cant believe how mobile it is. my jaw dropped when you picked it up. i'll save this video for when i have the space to use one of these. the PAPR i built from watching your video has been going strong and is really a blessing to have around! the quality and depth of your tutorials is top notch.
