Setting Up an Opt Lasers Diode Module with MASSO – Official Guide

Wiring with MASSO

As the manufacturer of high-performance diode laser modules, Opt Lasers provides seamless integration with MASSO CNC controllers. This guide covers the exact steps to correctly connect and configure your Opt Lasers module for laser engraving and cutting using MASSO’s intuitive interface.

Connecting the Laser Module to MASSO

  • Our diode laser modules connect to the MASSO spindle output port using a simple PWM/TTL signal cable.
  • The positive (+) signal wire connects to MASSO’s analog spindle output pin, while ground (–) connects to a GND terminal.
  • Ensure your power supply matches the specifications of your Opt Lasers module (voltage and current ratings).
  • Double-check polarity and signal connections before powering on to protect your hardware.

Configuring MASSO for Laser Operation

  • Enable the Laser Mode in MASSO settings to activate PWM control for diode lasers.
  • Adjust the maximum PWM output to match your module’s recommended input (typically 5V PWM).
  • Set the PWM frequency between 5 kHz to 20 kHz for optimal modulation with Opt Lasers modules.
  • Assign the correct spindle output port to control laser power through your chosen G-code software.

Laser Multi-Head Output Settings

When using multiple outputs or switching between spindle and laser operations, configure the Multi-Head Output settings in MASSO. This ensures smooth switching and prevents signal conflicts.

Test & Calibrate Laser Operation

  • Perform initial laser tests with low power settings to verify correct PWM response.
  • Use LightBurn or equivalent CAM software to generate simple G-code test patterns.
  • Adjust focus distance of the laser module for sharp engraving results.
  • Confirm power scaling and linear response for precise control during operation.
