I installed a THC system on my CNC plasma cutter. I tried many time without success to configure it to cut metal art on thin sheet metals (0.8mm and 0.5mm thick). The THC system only work for some thick sheet metals (1.5mm or above). For the thin sheets that I was using, The Z axis kept crushing into the sheet then lifted too high and ran away from the sheet metal.
I decided to give up on the THC and made my own mechanical THC. The setup that I designed can be adapted to any torch, CNC plasma system (Mach3, GRBL, etc…) and 100% success rate. You won’t need to do any wiring to your CNC controller or changes to your plasma cutter. You will only need to make your Z axis free floating by removing the limit switch (if you had one). The tip of the torch will be maintained at constant height while gliding and cutting on the surface of the sheet metal. The free floating Z axis will allow the torch to follow any type of changes on the surface of the sheets. The mechanical shield will constantly press on the cutting surface by weight.
The whole mechanical THC setup was easy to make using my CNC milling machine. You can adapt the setup to your own CNC plasma cutter by changing the inner diameter of the fixture ring to the diameter of your torch.
In the end, the system showed a great success with a really thin sheet metal (0.5mm). Despise all the warping, the metal art was cut beautifully and clean.

I rebuilt my CNC wood router and converted it to a CNC Plasma Cutter. I removed the CNC controller and installed a Proma MyPlasm CNC THC Controller and using a Everlast 80 AMP Plasma Cutter. This has been about a year project trying to figure everything out.

Ich weiß, ich weiß …… Es ist ein langes Video, aber ich wollte es nicht unterteilen.
Jeder baut eine CNC-Maschine, ich auch. Der Plan zu machen dauerte mehr als 190 Stunden, aber es hat sich gelohnt. Die Pläne können kostenlos von jedem unter dem Google Drive-Link heruntergeladen werden. Hier finden Sie alle Kunststoffteile in stl-Dateien. Ich hoffe, ich habe nichts von den Zeichnungen übersehen.
Wenn jemand Fragen hat, werde ich sie gerne beantworten. Ich hoffe, das Video wird allen gefallen!(inspiration from crossfire plasma cutting)
Um euch weiter auf dem laufenden zu halten und euch immer neue und größere Projekte zu zeigen , würde ich mich freuen wenn ihr mich durch eine kleine Spende unterstützen würdet .
Ganz einfach und unkompliziert könnt ihr dies auf https://www.patreon.com/Madebydad und https://www.paypal.com/paypalme/madeb… tun .
I know, I know …… It’s a long video, but I didn’t want to break it down.
Everyone builds a CNC machine, so I did too. The plan took 190+ hours to complete, but it was worth it. The plans can be downloaded for free from anyone at the googl drive link here. Here you can find all plastic parts stl files I hope I didn’t miss anything from the drawings.
If anyone has any questions I will be happy to answer. I hope everyone will like the video! (inspiration from crossfire plasma cutting)
In order to keep you up to date and to show you new and larger projects, I would be happy if you would support me with a small donation.
You can do this very simply and easily
