DM800 Offline Hand CNC Controller System 5-Axis

DM800 Ethernet CNC Control System Offline Controller

Overview:

The DM800 is a standalone CNC motion controller designed for upto 5-axis machines. It operates independently without the need for a computer, reading G-code files directly from a USB flash drive.

Key Features:

• Offline Operation: Reads G-code files from a USB flash drive, eliminating the need for a connected computer.
• Ethernet Communication: Facilitates communication between the handheld unit and the mainboard via Ethernet.
• Integrated SD Card: Comes with a built-in SD card for additional storage.
• User-Friendly Interface: Equipped with a 3.8-inch TFT screen for clear display and easy navigation.
• MPG Handwheel: Includes a built-in Manual Pulse Generator (MPG) for precise manual control.
• High-Speed Pulse Output: Supports up to 460KHz pulse output for each axis, ensuring smooth and precise motion.
• ARM Motion Control Chip: Utilizes an ARM-based motion control chip for reliable performance.
• Built-in Storage:
  • Internal 16GB storage
  • Includes a 8GB U-disk for file transfer
• Spindle Control:
  • 1 × 0–10V analog spindle output (can be configured to PWM)
