A material-first reference: standard, filled, nylon, flexible, high-performance and specialty filaments — pros, cons, TDS data and when to use each.
Printers / Compare
Compare printers
Put two or three machines side by side on build volume, speed, temperatures and materials. DIY designs and off-the-shelf printers compare in the same table, so you can weigh building against buying.
Electronics
Electronics
Every board, sensor and probe that goes into a Klipper printer — mainboards, host computers, toolhead boards and Z probes, each entry sourced from manufacturer documentation.
Electronics / Mainboards
MCUs & mainboards
Compare mainboard controllers for Klipper printers — stepper slots, CAN bus, processors, and compatibility.
Electronics / Host computers
Single-board computers
Raspberry Pi, Orange Pi, BTT CB1/CB2, and other Klipper host boards — specs, OS downloads, and setup guides.
Electronics / Toolhead boards
Toolhead boards
CAN bus, USB, and passive toolhead boards — EBB, Nitehawk, H36, Hartk, and more.
Electronics / Probing
Probes & bed scanners
Eddy-current scanners, nozzle-contact probes, inductive sensors, and deployable-pin probes for Z homing and bed meshing.
Firmware / Configuration
Klipper configurator
Assign components to MCU pins and generate a starter printer.cfg configuration. Works with stock Klipper and Kalico (a more cutting-edge community fork — configs are largely interchangeable).
Read first
Experimental configuration tool
This tool generates a starting-point Klipper printer.cfg configuration.
Output may contain errors or require adjustments. Always verify against official documentation before use.
When checked, the extruder motor, hotend heater, hotend thermistor, part cooling fan, hotend fan,
probe, and X endstop are assumed to be on the toolhead board (EBB36, Nitehawk, H36, etc.)
and will be omitted from the generated main MCU config.
TMC2209/2226 use UART communication. Verify the UART jumper is set on each driver socket.
Voron Tap uses the nozzle as the probe. Wire the Tap PCB signal to the Z endstop pin, set stepper_z endstop_pin to probe:z_virtual_endstop and remove position_endstop. Tap REQUIRES the official activate_gcode block so it never probes with a hot nozzle — it is generated for you below.
Sets Z rotation_distance (TR8x8 = 8, TR8x4 = 4, TR8x2 = 2). The official self-source BOM (R1 and R2) uses TR8x8; LDO kits ship TR8x4 integrated-leadscrew steppers. Trident R2 (Jun 2026) lowers the Z motor mounts for 320mm leadscrews with couplers.

Installing klipper-led_effect
Effects need Julian Schill's plugin. On the printer host:
cd ~
git clone https://github.com/julianschill/klipper-led_effect.git
cd klipper-led_effect
./install-led_effect.sh
Then add it to Moonraker's update manager so it stays current, as described in the project README. A plain [neopixel] section works without the plugin; only [led_effect] needs it.
