How to use PWM & Test Board for laser cutter module?

Note:These two boards are only used as test boards for neje module. Not needed for daily use.

TEST Board:

This board is usually used to check if the module is working properly.

How-to-use:

1．Do not connect the module. Only connect the 12V power supply to the adapter board.

2．Connect the 4P wire to the module.

3．Aim it towards a regular wooden board (Certainly not at people or flammable items), and then press the test button on the laser adapter board.

Description:

In step 1, the RED LED on the adapter board will light up.
After connecting the laser module in step 2, the BLUE LED will flash, the fan of the laser will rotate, and the LED on the laser will flash. Fan may off after 1 second.
In step 3, when you press the test button, the laser will work at full power. If the above situation does not happen, it may be that the module is damaged. In this case, you can shot a video or picture of your test and upload it to the forum, and a new module will be sent to you directly.

PWM Controller Board:

Unlike the test board, the PWM board is usually used to manually control the laser power of the module.

How-to-use:

1. Do not connect the laser module, connect the 12V power supply to the board
2. Connect the 4P wire to the the module
3. Press the ℃ （temperature）button
4. Press the switch key to switch to test mode, and 001 should be displayed at this time
5. Press the PWM - and PWM+ key continuously control the laser power of the module

Normally:

In step 1, connect the power supply to the laser test board, and the test board should display the “off” sign.

In step 2, after connecting the laser module, the last point of the digital display should flash.

In step 3, press the ℃ button to display the module temperature.

In step 4, the nixie tube should display 001. At this time, “test mode” should be on instead of “TTL in” led. At this time, The laser should be a very low power output.

In step 5, the laser intensity will gradually increase or decrease.
