How to make laser module work with your control board

First: you need to know which pin is PWM output pin of your control board

There are many kinds of control boards on the market. We can’t test each control board. Here is only a general method to confirm how to connect. The following methods may have errors. Please consult your control board vendor for details.

  1. Generally, PWM output pin will have PWM mark, TTL mark or LASER mark nearby.
  2. On Arduino, For Grbl v0.8 and v0.9+ with variable spindledisabled,  pwm output is D12.
  3. On Arduino, For Grbl v0.9 and v1.1+ default builds, pwm output is D11.

Here is an example on MakerBase MKS DLC v2.1:

Second: Connect laser module to your control board.

Here is 4 ways connect laser module to your control board:

  1. Hello
    I need help connecting the NEJE A40640 laser module Laser engraver / cutter Module ktis – FAC tech – 2 x laser beam – 15W output.
    I have the current analog laser connected to PWM | GND | 12V
    (red arrow).
    If I connect my controller through the Neje Laser adapter as shown in the picture (yellow and black arrows), will it work?
    If I understand correctly, the controller must have a separate power supply and the laser has a separate one.
    I will add that the controller has GRBL 1.1f installed
