Yeah, it's a tough price point. Remember, he says he's working hard to hold down the prices. If he can do it, unassembled, it would be great. I paid that for rails and ballscrew for one axis alone, but it's a different class of machine. BTW, I think you're way heavy on the material and fab costs, except the motors. $300 to cut and stamp 20 lbs of 12 gauge? I'll walk, Buddy. OTOH, $50 won't buy the steppers and drives for one of the gas-pipe toys, and really pushing the line on even a single 90 ipm axis. $600 turn-key, unassembled, is just close enough to the line to be believable. I'm rooting that he makes it. I have room and need for those capabilities. ----- Original Message ----- From: "mikezcnc" <eemikez@...> > Having said that, instead of describing a pattern of behavior, I am > asking a question, can a machine, like Fred listed, be built for $600 > with stepper motors and a controller?
