Your thoughts on an inkjet hack Answered
I've been mulling around a cheap (as in free) way to make a 3d printer, or laser engraver. I'm looking for flaws in this plan: 1)Find an inkjet printer thrown away because new ink would cost almost as much as a new printer. 2)Mod the paper feed motor assembly so that the it moves the top half of the printer along a rail instead of moving paper. 3)Short out the pins to ink colors other than black to give a false "full ink" value. 4)Attach a power transistor to a cutting laser circuit, and the black ink pins. The idea is that if I sent a black and white image to the printer, this could perforate or even cut a suitable material. I already have a few areas I'm concerned with, but I'd like a second or third opinion on possible trouble areas.
