C3Dt/cXY Core XY 3D printer

The CoreXY printer I designed and implemented is my center piece of printer. I use it for most my printing needs and continually keep adding features.

The wish list for this printer started out as follows:

  • Sturdy design that should be transportable without fear of breakage.
  • Aesthetically pleasing (no loose wires all over the place and proper finishing).
  • Ramps 1.4 with a larger display, with possibility of upgrading in the future .
  • Enclosed chamber with possibility of heating chamber (lot of issues with warping using ABS on Prusa I3).
  • Larger bed. For starters 300×200 with room to grow.
  • Heated bed (of course).
  • Dual extruder (something I came back from).
  • Use of linear rails where possible instead of rods.
  • Easy accessible electronics.
  • Easy to swap out extruder (with possibility of possible replacement with Laser or spindle)
  • Internal lighting.
  • Independent heat control for chamber heater with.
  • Auto Bed leveling using an inducer.
  • Cost effective. In order to keep cost down most items were purchased directly from China.
  • Must be able to at least print at 75 micron

As I started designing this printer I came across the principle of Core XY motion which I was fascinated by. This printer has been implemented using CoreXY.

New features will keep coming but here are the current specs:

Dimensions: 610mmx610mmx820mm

Build plate: 330×220

Build volume: 200x300x305 (x/y/z)

Additional build plates for easy print removal and bed covering (one plate for ABS, one for other materials)

Heated Bed (Silicon 110v)

Extruder: (Genuine) E3D Titan extruder (direct extruder)

Nozzle: 0.4mm

Controller: Ramps 1.4

Motion: CoreXY (2x 2Amp steppers)

Guides: Linear Rail (THK 12mm)

Auto Bed leveling

Heated Chamber with separate power (110v) and thermostat

Frame built- in LED lighting

Filamament cooling fan

Automatic Nozzle cleaner using Marlin’s experimental nozzle g-code

As time permits I will try to cover many of these features in dedicated posts.
