this is the cleanest cut I have seen on a DIY plasma cutter. Kudos

Ah yes, the chinese laser conversion- I plan on doing the same thing with my first plasma cutter, especially since I'm already familiar with lasers like this. You got some really good clean precision by the look of it. Nice work!

Killer project mate, I know everyone means well but jeas they may as well ask you to build the bloody thing for them (which you have 98% completed anyway). 😂

Marcus, this is the best portable and clean build I've seen so far. by the way, It's a 60cmx60cm working area? cheers from Honduras mate!

Bro i love your build. I just found your video making research of doing something very similar to this. Can i ask you several questions about your build that are bugging me. What plasma cutter are you using is it High Frequency ? Did you suffered many problems with EMI, How did you manage to overcome them? How do you communicate with the control board vie usb or something else? Once again pretty nice build bro!

Hi there. Thanks for the comment! I'm using a cheapo chinesium CUT-60 plasma with a no-name tube torch that I got off ebay. I made a build blog for the CNC-part of it all here www.runstenracing.se/?cat=61

The plasma cutter does not have HF-start so I had to make a custom start script where it goes down to the material, starts the plasma and then raises the torch a few mm above the material. I'm using a standard 32-bit 3D-printer control board to run the stepper motors and a Raspberry Pi with Klipper to parse and execute the G-code. Since it's for 3D-printers I had to make some customizations but nothing major. The way I set everything up I could do it all in the klipper configuration without changing any of the code. I've got some EMI issues still without the HF but as long as I run 42A or less it works perfectly. The Raspberry Pi has built in WiFi so I push the g-code to the cutter over WiFi and control it all using my phone and the Klipper web GUI. I had to make a custom post processor for the plasma that I use in Fusion360 to make the g-code and it works flawlessly (more or less).

Bro can you share to me please 🙏 about step by step build this cnc plasma cuting , 🙏🙏

Very good work, i have a similary build, but i have a big problem with electromagnetic disturbance, my arduino reboot when the plasma start the cut... do you have found a solution for this problem ?

@marcusrunsten

Жыл бұрын

Do you have HF-start on your plasma cutter? Mine doesn't and HF start is one big reason for EM problems. Still, I can't go over 42A on the cutter or the controller restarts randomly. The solution for this I think is moving all the wires further from the nozzle and not routing the cutter hose close to any cables. Before redesigning the Z axis again to try to mitigate the problem I'm going to try adding ferrites to the stepper- and limit switch wires since that's a much easier operation. I've tried shielding all unshielded cables with aluminium foil but that did nothing. =) With that said, 42A is about what my fuse can handle for any prolonged time so it's working pretty well as it is. But there's always room for improvement.

​@@marcusrunsten No HF with my plasma cutter, i buy a shielded cable for my stepper and limit switch, as soon as i get the cable i will try that! Thank you for your answer, hello from France 😀

Жыл бұрын

Keep me posted. :) Shielded cables is a must-have on a plasma cutter like this. Try routing the stepper and limit switch cables as far from the torch hose as possible. I've got all the electronics routed in drag chains along the axes of the machine and the torch hose suspended from the ceiling going more or less straight down to the torch. Still, as I mentioned, I get cut-outs at more than 42A. Since I'm lazy I haven't really tried to solve that issue since it works for me cutting 4-6mm steel sheets.. I'll add the ferrites and post an update if that helps with the interference.
