The idea
Slicing software and printed models are the visible part of 3D printing. This project is about the layer underneath — the motion control that actually moves the toolhead — and whether I could build that myself.
What it does
A concept for a custom controller for an existing 3D printer, using a Raspberry Pi Pico (RP2040) running Klipper firmware, with X/Y stepper control, dual-Z configuration, and TMC2208 drivers under consideration.
How it works
The scope under exploration includes filament runout sensing and thermistor integration alongside the core stepper control — essentially reassembling the motion-control hardware of a 3D printer from individually selected components instead of an off-the-shelf board.
Progress and outcomes
This is a design exploration at this point, not a built and running controller.
What comes next
Moving from component selection into an actual build and Klipper configuration.
