GRBL 4-Axis Stepper Motor Driver Controller For CNC Router Laser Engraver Cutter
--ARM32-bit control board 32-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. --X/Y/Z/A four-axis drive, Y-axis double drive. Support for rotary axis. More powerful driving ability. --All signals are isolated by optocoupler, with strong anti-interference ability. Optocoupler isolation technology, strong anti-interference ability, more accurate engraving. --It can be connected to 300W/500W spindle. It can be matched with spindles of various powers, with higher adaptability. --PWM/TTL software to adjust laser power. PWM output frequency 10kHz, higher engraving precision and clearer details. --Split design, control, drive, and expansion boards can be replaced. Split design, more convenient to use. --6-way limit switch, 5V/12V/24V constant voltage pins. --5V power output port, software controllable, easy to expa
