Product Description：
1. ARM32-bit MCU control board, running faster, the maximum no-load speed reaches 40000mm/min, better algorithm optimization, less vibration when the machine moves at high speed, and more stable performance;
2. X/Y/Z/A four-axis drive, Y-axis dual drive. Support for rotary axis
3. The control board power supply and line number circuit use optocoupler isolation, the entire control board is safer, more stable, and has strong anti-interference ability
4. External 300W/500W spindle
5. Split design, control, drive and expansion boards can be replaced
6. limit switches, 5V/12V/24V constant voltage pins
7. Can be connected to a high-power driver
8. Stepper drive subdivision adjustable
9. Can connect 775 motor/3pin laser 4pin laser/offline controller. Reserve 24V, 12V, 5V power output ports to facilitate the expansion of various functions
10. PWM/TTL software to adjust laser power
11. Support USB flash firmware, firmware upgrade is more convenient
