The PWM controller accepts the control signal and adjusts the duty cycle of the PWM signal according to the requirements. 70 for 2axis USB Control. In order to control the power of the laser tube, the laser PSU reads a PWM signal as it's input. By putting the laser on another gantry, say at the far end of the table, then you would be able to use a laser controller that controls its own stepper motors and the nozzle can have fast swing motion for engraving. PWM stands for Pulse Width Modulation, which in itself is not very useful if you don’t know what modulation is. Aircraft aluminum heatsink with cooling fan ensure long working time continuously. As the control signal is a PWM (in case or servo motors, it is technically Pulse Position Modulation or PPM), the control wire or orange wire must be connected to any of the PWM output pins of the Arduino UNO board. Pulse-width modulation (PWM), as it applies to motor control, is a way of delivering energy through a succession of pulses rather than a continuously varying (analog) signal. FSCUT2000S.
