"Origami" CNC Plasma Build - folding 1200 x 600mm cut area

Looking niceeeee !

Well some news ...




And then a close up of what was cut and how it came out:

-Nozzle to high
-air pressure low
-speed to high
-current to low
From your video, the last two, it seems, or the first.
Clean machine!
Enjoy it, it will be dirty very soon.

Thanks tommylight. I have upped the air pressure. Higher speed seems to improve dross. 40Amp on 2mm should be ok? Think that was running at 2300mm/min. Slower does not improve dross levels that I can see. ~2640mm/min seems better.

I'm doing some test at that speed dialing in the kerf size. Also need to get more ridgid torch holding. But still stocked its actually starting to cut.

Now need to start thinking about water table, THC and no doubt some other refinements that will come up.

After a lot of trials and testing here is the first "complex" part cut.  Still in 2mm mild stee, which is perfect for mount to be folded for my TYT MD-9600 radio.

 

And here is the video of the cutting process.   Key details are:
Feed: 1700mm/min.
Amps: 40
Cut height: 1.5mm
Pierce height: 3.5mm
Material: 2mm mild steel sheet
Lead in: 4mm perpendeicular
Overcut: 1mm
Not saying these are optimal (e.g. overcut might be better to be -2mm with a perpendicular lead out)


Cheers - James.

Manged to dig out some 6mm steel and try a test.   Used the settings straigt out of a cut chart I found.
1200mm/min, 1.5mm cut height, 3.5mm pierce height, 45A, 4mm lead in and 1m overcut.  Not a bad effort for a firsyt test cut on that thickness.  But MAN the smoke!  I'm going to pack things away a bit and get on to sorting the water table.  The smoke/fumes are cracy.
