Nano LIGHT SABER Plasma cuts Alu, Steel, Titanium and more... Rack Robotics Wire EDM @ RMRRF 2024.

Описание: Turns out TEMPERATURE DOES MATTER! Cut through hardened metals using Plasma hotter than the Sun (surface) like butter. Way better than so called "(GIANT MEGA SABER)" propane based devices, which at best can only cook buttered popcorn 🍿.

Visited RMRRF 2024 recently and saw Rack Robotics ( RackRobo ) neat open source hardware/software tool for cutting metal using Wire EDM (Electrical Discharge Machining).

0:00 Demo, cutting 0.5 Aluminum
0:15 Q: What's max cut thickness? Ans: 32mm-60mm, can build custom larger machines, e.g. 1000mm!
1:00 Demo, more nano plasma cutting...
1:10 WAGO connectors for the win!
1:15 Demo, even more nano plasma cutting...
1:30 Q: What's happening? Ans: Vaporizing metal workpiece, and brass rod tool, using thousands of lightening bolts and plasma every second.
1:52 Can cut any conductive material. e.g. Alu, stainless steel, hardened steel, titanium, tungsten carbide.
2:12 Cooper touches rod. ME: Err... Is this High voltage? Cooper: It's high voltage, and high ampage 100A per spark, but only in very short bursts (microsecond sparks).
2:44 Example of printer hotend sliced in half.
2:52 Ender 3 Printer modded for Wire EDM
2:59 Selection of cut stuff
3:25 Lead free brass rod for demo hand held nano lightsaber.
3:40 Tour of the Wire Tool (modded Ender 3),
0.3mm brass wire pulled through under tension, ceramic guide.
4:28 Using Distilled water
4:34 "Power Core" with high quality components used to generate high frequency, high power pulses.
5:12 Brass wire spools sold for $20 for 250g, provides 7hrs of EDM cutting (~414 meters).
5:58 Check out "PowerCore" if you want to build or buy one.
