This is the cutter I built. It can handle two 3x4x10 blocks at once, has 4 axis capability and a 5th axis turntable. But I was using a DC power supply to heat the 84" Nichrome wire and for some reason the PS died when I was almost done with the first job. Any ideas? Someone has told me that I should be using a "Variac" but, being A/C, that sounds dangerous. What do you think? Thanks
