Pulse width modulation (PWM) is a technique to obtain analog results by digital means. When replacing the control panel, we must pay attention to ensure that the USB interface is connected to the machine normally. This part is mainly responsible for connecting the machine to PC. The basic structure of the upgraded controller is shown in the figure, which is mainly composed various interfaces of stepper motor, PWM, limit switch, and these interfaces bring more possibilities to the machine. Monport grabl control board structure and working principle It can be used as upgrade substitute for nano controller. Its firmware and ports can also be used to control similar engraving machines and some CNC machines of other manufacturers. The grbl controller is developed for Monport 40W CO2 laser engraving machines and most other 40W machines, which can engrave and cut glass, leather, plastic, wood, etc. ![]()
