I'm also hoping to stay under $1000. I'm trying to build a 24" x 48" machine running belt driven homemade drive nuts turning on 2 start 1/2-8 acme screws. I've already got my Z-axis bearings, 2 253 oz-in steppers, xylotex boards (3axis + single - 2 motors on moving gantry). If my design works as planned, I should finish somewhere in the $1000 range. If it doesnt work, I'll build a smaller, more conventional machine.
