Very nice indeed, I have seen it before and watched it to the end.

May I ask what was the reason to have an upstand on the floor as a trip hazard. Could it have been done with a blanking plug to fit in flush.
 

Made some fishing rod holders the other day. 1.6mm steel. Quite impressed with the lack of dross on the cuts now I have a proper torch on the CNC.

A couple of brackets I cut out then welded together to motorize a bead roller.Now I want to make my table larger for more travel.

Nice table. Could you share a photo of your torch holder? I have to make something like that for the same torch.

Question, how is your machine so clean???
Also what Rod said, i might have to buy a new plasma source, some china Kzubr with 100A plastered all over it for 600 Euro, and it comes with such a torch.

The torch holder? LOL! My torch is a Hypertherm T30V. It is just a 30 AMP unit that they claim won't work with CNC, but there are spots directly on the circuit board for external switching, and the THC was easily integrated into the board as well. I'd love to upgrade the plasma for thicker material, but for now it is what it is and it cuts the prototype parts out amazingly well. I thank the whole community that has worked so hard to offer the support for this open source project using free or very affordable software. I'm actually beginning to like Linux.

I cheated on my table.  I bought the table with slats from JEGS for $150, and added my x-y-z and modified the table to accept a stainless water pan.  It's a bit small, but when I started this project, I didn't have a huge area to store it and I wasn't convinced how useful it would be and figured that if it worked out and I wanted to, I could scale it up.  Scaling up would be easy with the control panel I built along with all the learning in building this one.

My hand torch has a 1" (or really close to it) collar, and as I sat there contemplating how best to make a holder that would allow consistent and firm holding while also allow quick detachment so I can still use the torch by hand, I looked at my bench and there sat some rifle scope rings. I dug through my stuff and found a short section of rail, and a 1" ring and my torch holder was complete!

I do need to incorporate a magnetic break-away so I don't destroy the torch or machine. The reason (as I found out) being that if the torch travels over a section of sheet metal that has fallen through into the water table slats, the torch can get caught on the edge of the sheet that is still there and it will drag the sheet around as the torch moves. (Luckily, I was there and an E-Stop stopped the excitement).

Here is a picture of the riflescope ring.  I hadn't seen anyone else try this, but it has worked for me.  One day, I might try to create a machine torch, but at the same time, it's sometimes handy to use the torch by hand.
