LDO ROOK MK1 - CoreXY 3D Printer Kit for Beginner

The core idea is “fewer detours + maximum playability”: single-motor belted Z, a triangular bed frame, a pre-drilled frame grid, and the Rookery toolhead ecosystem, so you can keep expanding the machine to match your needs.

Ideal for high-speed desktop small parts; learning Klipper tuning; a handy second printer; testing ducts and toolhead mods.

LDO Version Upgrades & Improvements

ROOK MK1 (with the LDO kit) offers structural, ecosystem, and component-selection advantages vs. typical builds: more stable, more precise, faster to build, and easier to assemble.

01. Belted Z

The Z axis uses belt-synchronized lifting, reducing complexity vs. multi-motor or lead-screw solutions. It moves more smoothly with a lighter structure and is easier to maintain.

02. Triangular Bed

A triangular bed frame with rear bearing support improves leveling and support stability, and it can accommodate different bed-surface options such as glass, magnetic sheets, and heated beds.

03. Pre-drilled Frame Grid (25 mm Grid)

25 mm spaced mounting holes on the sides/top/bottom make expansion easier: panels, braces, cable routing, and peripherals can be mounted quickly.

04. Rookery Toolhead

Rookery replaces traditional cooling structures with dual-fan direct mounting and a quick-removal installation method. It improves part cooling and bridging stability, and makes maintenance/modding easier.

05. Unified Kit Component Selection

The kit specifies the core hardware (e.g., BTT M4P + CB1 + TMC2209, Trianglelab TR6 CHC hotend, and a DDB dual-drive extruder). Key components are better matched, reducing compatibility pitfalls and speeding up the build.
