GRBL 4-Axis Stepper Motor Driver Controller For CNC Router Laser

--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 expand various functions. --It can be connected to a high-power driver. --The stepper drive subdivision is adjustable, and the machine operates more accurately. --It can connect 775 motor/3pin laser 4pin laser/offline controller. --Built-in laser anti-burn mode, laser S value >=100, after the laser is turned on, if there is no movement within 5S, an alarm will occur. A4988 driver and 8825driver can be replaced with each other --8825driver , 2A it is better for Nema23 57 Motor --A4988 driver support most Nema17 motor.
