Comprehensive Technical Specifications
| System Classification | Fully Enclosed, Custom-Programmed Commercial-Grade CoreXY Production & Educational Platform |
|---|---|
| Open-Source Programming | Bespoke open-source firmware configuration written and optimized exclusively for this machine's exact kinematic layout, custom macro routines, thermal safety algorithms, and closed-loop feedback loops. |
| Chassis & Frame Engineering | Ultra-rigid, un-twistable frame constructed from 4x 2040 Z-beams and 16x 2020 extrusions integrated into 8x 2040 interlocking members. Reinforced with heavy-duty ABS printed corner brackets and secured by 21 M5 high-tensile bolts with Misumi slot-in T-slot nuts per corner, yielding structural rigidity comparable to high-specification industrial CNC systems. |
| Build Platform & Bed Assembly | Precision-milled MIC6 350mm x 350mm x 8mm tooling plate paired with a 350mm x 350mm spring steel sheet secured via a high-performance magnetic top surface. Supported by heavy-duty Z-drive brackets with industrial GE5C spherical bearings and custom waffle-pattern TPU pads to isolate and absorb high-frequency vibration distributions. |
| Thermal & Enclosure Management | Fully enclosed thermal chamber engineered for high-temperature engineering-grade materials processing, equipped with 2x recirculating activated carbon filter fans for active chamber air filtration. Powered by a 750W 230V silicon build plate heater governed safely by a 24V signal through an iAutoc 25A solid-state relay (SSR) featuring an integrated 135°C safety thermal fuse. |
| Processing & Core Control | Powered by a Raspberry Pi 5 (4GB) running custom-configured open-source host software, communicating with a BigTreeTech Octopus Pro v1.1 H723 (550MHz MCU) motherboard utilizing 6x TMC2209 stepper drivers operating in silent UART mode. |
| Toolhead & Extrusion Mechanics | Decentralized H36 toolhead board controlling printhead electronics via reliable CAN-bus architecture from the main MCU. Equipped with a Phaetus Rapido v2 Ultra High Flow hotend and a dual-stage dual-gear direct-drive extrusion system designed for maximal filament grip and torque. |
| Motion Kinematics & Gantry | Driven by LDO Speedy Power XY motors on a carbon-fiber reinforced ASA monolithic gantry. Linear motion is governed by a precision single MGN12H rail on the X-axis, dual MGN9H rails on the Y-axis, and quad MGN12H rails on the Z-axis, featuring upgraded GE5C spherical Z-joints for zero-binding vertical motion. |
| Calibration & User Interface | Integrated Cartographer Eddy Current Sensor for ultra-fast, high-precision non-contact bed mapping, managed through an intuitive 5-inch touchscreen control console. |
