Hey guys what’s up it’s Alex over at Laser Everything and today I’m going to be walking you through, step by step, on how exactly to downgrade your Ezcad 3 controller to an Ezcad 2 controller. Why on earth would you want to do this? Well, the initial release of LightBurn for Galvo lasers will only work with Ezcad 2! Now, to be clear, Ezcad 3 support isn’t hopeless but it’s far from confirmed. If you want to be absolutely sure you can use LightBurn with your Galvo laser this is the guide for you! Focus up! This is going to be a tough one, but if you follow the instructions you should be able to tackle this project without any special skills or experience. Enough chit chat, let’s get into it.
