GRBL 4-Axis Stepper Motor Driver Controller For CNC Router Engraver Cutter

Product description: 100% brand new high quality Made of high-quality materials for durability GRBL 4-axis stepper motor driver controller for CNC router off engraving and cutting machine ARM32-bit control board The 32-bit MCU control board runs faster the maximum no-load speed reaches 40000mm/min the algorithm optimization is better the vibration of the machine is smaller when the machine is moving at high speed and the performance is more stable. X/Y/Z/A four-axis drive Y-axis dual drive. Rotation axis is supported. 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. Can be connected to 300W/500W spindle. It can be matched with spindles of various powers and has stronger adaptability. PWM/TTL software adjusts power. The PWM output frequency is 10kHz the engraving precision is higher and the details are clearer. 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 pin. 5V power output port software controllable easy to expand various functions. High-power drives can be connected. The stepper drive subdivision is adjustable and the machine runs more accurately. Can be connected to 775 motor/3pin 4pin/offline controller. Built-in light burn-proof mode S value>=100 after the is turned on there is no action within 5S and an alarm is issued. Packing list: 1 * 4 axis controller 1 * Type C cable 1 * Motor cable Note: 1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2.Please allow slight manual measurement deviation for the data.
