Compatible with plus, mix, max machines Master 2 needs to install a slider module, because this module can only be installed on the sliding slot, you need to slide up and down to adjust the focus.

The third yellow interface line is the TTL control line, the voltage range is 3.3-12V, the frequency is 0-20KHz, and it needs to be grounded. 2. The input voltage of the red and black wires is 12V3A - 12V5A, do not connect them in reverse, otherwise the module will be damaged. 3. The power is not controlled by voltage or frequency, it is controlled by duty cycle. **[[http://www.neje.club/download/20200612/How_to_get_laser_temperature.pdf|How_to_get_laser_temperature.pdf]]** {{https://nejetool.oss-us-west-1.aliyuncs.com/wiki/module_public/focus.jpg}} Show page
