Change Log

  • As of 12/3/18 v18.10 - known bugs are: positive bump endstop holder does not fit around motor just by 1 mm, whereas magnets worked before as they had play. Print Cooling Fan: needs nozzle optimization. X axis mounting: needs procedure optimization for axis tightness. Print area: using 2016 extruder holder eats up bed space; need to optimize bed space. Print volume: optimize extruder mounting to access 3" of additional vertical space with horizontal X axis mounting. Needs: 3D Printer Workbench Specification. End cable chain: needs bigger hole. Fan mount: thinner + 100% print

Production Engineering Improvements

  • Idler detail - nut catcher cleaning + half circle cleaning
  • Carriage - half circle cleaning
  • Motor - hole cleaning, nut catcher cleaning
  • Endstops - get rid of them via trinamic or modify bump version
  • Spool holder - hole fit
  • Sensor holder - sensor fit

HintLightbulb.png Hint: Note that to design new versions of the 3D printer, you want to use small, simple files. We have ones ~20k for each axis.

  • Note that D3D_Part_Library#Assembly_Index contains the simplified assemblies. These are to be used any time that a new version of the 3D printer is to be designed from scratch.
  • Simplified axis files - X, Y, Z - the smallest ones today are also used on the D3D CNC Circuit Mill
  • D3D Integration has files that are on the order of 5MB and 1MB for each axis. Still too large for prototyping.
