OneLaser Hydra Upgrade | Install Compressor Air Assist for Cleaner Cuts & Engraving

In this video, we’re upgrading the Hydra 13 laser with a compressor-based air assist system! 🚀 If you do a lot of cutting, having high airflow is essential for cleaner cuts, reduced char, and minimal smoke or flare-ups. This guide will walk you step by step through installing and wiring the OneLaser air assist module so your Hydra is ready for both engraving and cutting.

We’ll cover everything you need to know — from bypassing the stock solenoid, wiring the relays into the controller, routing airlines, and setting up regulators, to dialing in your PSI levels for low-flow engraving and high-flow cutting. I’ll also show how to integrate air assist controls directly into LightBurn, so toggling air on/off in your layer settings automatically switches between low and high flow.

What you’ll learn in this video:
