Spokane Create Delta Printer

[ABearden]

Sure! I redrew and cleaned up my sketches a bit, but here's the basic layout of the frame panels. Someone please double check my math. Overall, they're 5/8" guide rods, 1.5" apart, with a 3/4" margin from the edge of the plate. Equilateral triangle with truncated corners. Effector/Traxxas rod + platform + hinge distance (basically bottom of the upper guide rods to the bottom of the lower guide rods) should be about 20.5" assuming 18" rods, 2" platform, and 0.5" allowance for carriage hinge. That distance is rough, but the final measurements can be compensated for in the firmware. Important part is the guide rod towers are equidistant and identical.

It doesn't include the M5 mounting holes, which I was thinking of changing to 5 per tower: one at each corner, one inline with those two spaced between the guide rods, and two more along the print edge (same distance from corner boltholes as the center bolt). The center bolt might not be required, or could be moved to the interior instead of the edge. Might be overkill, but would keep things tight. Would require 90 M5x30 bolts (I ordered 100 with matching nylok nuts, so this is very doable).

This will serve as the parent design for the 6 frame plates in the design. Then modifications will be made based on the location. All of them can be hollowed in the middle for weight savings and/or design (figured the Spokane Create logo needs to go somewhere). We can also turn it upside-down and put the motors and controller on the bottom if need be, but I don't see the increase in mass being a huge problem with as hefty as the frame is (physics enthusiasts, feel free to chime in on this!).

• Bottom-most: guide rod holes only halfway through.
  
• Bottom-middle: same as base design, all holes pass through.
  
• Bottom-upper: needs addition for belt tensioners between guide rods, and plate-mounting brackets.
  
• Top-lower, top-middle: identical, need modified pathway for belt (relocated middle bolt), requires center path for Bowden tube.
  
• Top-most: also needs belt and Bowden pathways, requires bolt layout for mounting motors/controller/extruder, guide rods only halfway through.
  

Really excited about how much involvement I'm getting on this, thanks guys!
