As the title says it is approximately 350mm x 450mm in working area. Most of this build is due to what I have laying around. Not totally opposed to changing things as long as it significantly improves the functionality.
Main features:

  • Chinese standard linear motion. SK10 bearing standoffs, SCS10UU bearings, 10mm bearing shafts
  • SFU1204 ballscrew because it really wasn't much more expensive than other alternatives I found
  • 350x350mm 110VAC silicone heater controlled from a SSR
  • 8020 10 series (1inch) aluminum profile (because I had a small stockpile)
All aluminum build except z-stage and z-plate (.75 maple plywood because its stiff and I have extra)
Bowden with hexagon hotend (not designed in yet)
Reasoning behind most choices is because I either have it, or can make it very easily (5'x5' cnc router that cuts aluminum and lots of scrap .125" plate)

Design is still pretty rough, I would love to get feedback on the cantilever idea of the z-stage. Z-stage is makerbot style and will have springs to adjust flatness. If I have to redesign it shouldn't need much more than 2 more screws, another rail and recutting the z-stage
