3 Axes GRBL Control Board USB Plug in Interface GRBL 1.1F 3 Axes Engraving Machine Control Board

Feature: 1. Offline Laser Engraving: The engraver control board adopts GRBL1.1f firmware for stable performance and offline module for offline tool setting and engraving. 2. Adjustable Power: The laser of the engraver control board supports PWM or TTL signal control, with adjustable power between 0-100 percent. Spindle supports PWM power 0-100 percent adjustable. Enhanced spindle drive can support 20000rpm. 3. Over Current Protection: GRBL engraver control board has over current protection and short circuit protection with 2A high current. Case protection while avoiding short circuit and fan active heat dissipation. 4. Offline Identification: The engraving machine control board uses integrated imported stepper motor drive, integrated heat dissipation aluminum alloy, add offline identification, can be plugged into offline module and computer at the same time. 5. Plug in USB Interface: The spindle drive of the engraving machine control board adds optocoupler isolation to make the control board generate less heat, spindle speed adjustment is more linear and safer, and the USB interface is plug in.
