I thought I'd make a quick video about the Arduino based CNC Plasma cutter that I made in the farm workshop.
EM interference was a major issue however, to overcome this I;
Used shielded wiring
Installed a stainless steel water bed
Put ferrite magnets everywhere
Earthed everything I could
Major parts include;
Arduino UNO
CNC shield V3
1.9Nm Nema 23 Stepper motors (2.8A)
24V Power supply
DM542T Stepper driver
HIWIN HGH15 linear rail (A must have item for an accurate system in my opinion)
5V 1 channel Relay Module with Optocoupler (For on/off plasma arc)
"Tool Mate" Plasma clean from Hare and Forbes Machinery House
Software im using;
Arduino IDE for flashing the arduino
Fusion 360
Universal G-code sender
