Specifications:
Both models are perfect replacements for the Duet2, at a lower price.
The CK407M5 and CK407M8 are high-performance 3D printer control boards featuring five-axis and eight-axis silent drivers, onboard Ethernet, and extensive expansion options. A single board handles complete control, from motion and thermal management to networking and local audio. Designed as a master controller for 3D printers and CNC/automation applications, it integrates motion control, power output, networking, and HMI capabilities onto a single PCB. The board is based on a high-performance 32-bit Cortex-M4 MCU and features 8-axis TMC2209 silent stepper drivers, supporting complex mechanical configurations such as XYZ, multi-Z, or extruder and auxiliary axes.
Motion and Drivers: The CK407M5 5-channel smart driver and CK407M8 8-channel smart driver support UART online configuration (current, microstepping, StealthChop, etc.), facilitating a balance between quiet operation and precision. With fully exposed step, direction, and enable interfaces, they are compatible with various custom 3D printer configurations, including Cartier, Delta, and CoreXY.
Connectivity and Interfaces: On-board Gigabit/100Mbps Ethernet (R45) for easy wired networking and remote monitoring; USB Type-C for firmware updates and debugging; Micro SD for local configuration and file storage.
Reserved pins for serial displays (such as PanelDue), diagnostics, and expansion headers to facilitate secondary development.
Thermal Management and Safety: Multiple heating and power control interfaces support heated beds, multiple extruders, and auxiliary heating; multiple fan and limit switch/probe inputs meet daily printing and safety interlock requirements.
Temperature measurement supports analog NTC100 thermistors or PT100 + MAX31865 (SPI) solutions (module support required), suitable for high-precision temperature control scenarios.
Audio: The analog audio path can utilize a stereo DAC, paired with an amplifier output and a 3.5mm audio jack, for power-on prompts, alarm tones, or voice prompts (subject to the factory BOM).
Software Ecosystem: Compatible with the RepRapFirmware (RRF) framework, supporting web interfaces (such as DuetWebControl), macro scripts, and network-based configuration, facilitating OEM integration and secondary Scenarios: High-performance FDM 3D printers, educational and research platforms, modification kits, and custom devices requiring quiet operation, network connectivity, and multi-axis capabilities.
