WaveTopSign M3 Nano Laser Control Card For K40 Laser Machine

Product Advantages： Multifunctional Multiplexing Button: 1. When working, click the button to automatically switch to the pause / restart function. 2. When repeating the work, click the button to trigger the function of engraving the next workpiece. 3. It can be connected in parallel to open the cover to protect: when the laser machine is working, opening the cover will automatically suspend the engraving, and closing the cover will continue to engrave. Note: Using the old version software, only can point laser. PWM Laser Control： 1. V+ PWM TL GND, the terminals are similar to those of the laser energy control panel. 2. V+ (5V on the laser energy control panel), considering that some laser power supplies require 3V PWM or 3.3V PwM, V+ can be connected to either 5V, 3V or 3.3V, and will automatically adapt to the needs of the laser power supply according to the connected V+ PWM voltage. 3. PWM corresponds to the IN of the laser energy control panel.
