Story
I'm designing and building an entire large 3D printer from scratch for ~$340!
I've completed the design, and I'm currently waiting for the final components to arrive and the finals parts to finish printing!
Click here to check out my Journal (including progress updates!) of the design journey!
Or here for an explanation of some design decisions!
Here's the BOM (if you want to build your own!): Google sheets
And the CAD model: Onshape
About the printer:
- 440x230x260mm printing volume
- 940x410x465mm frame
- Reuses a lot of parts from two "broken" Anycubic Kobra 2 Neos
- Direct drive extruder & dual 5020 part cooling
- Completely enclosed electronics
- Build-in ABL & Nozzle offset sensor
- With a rpi zero & Klipper-Ready
- A custom pcb for fan & led control
- ~$340
The custom PCB features:
- 24V power input
- Build-in 5V 3A Stepdown (for RP2040 and external RPI)
- RP2040 with 128MB Flash
- 3 Port USB hub
- 1x UART connection
- 1x ARGB connection
- 2x High current 24V PWM outputs (5A)
- 4x Low current 24V PWM outputs (2A)
