Documenting the Glowforge Power Supply

This repository aims to contain a collection of information on the power supply within the Glowforge Pro.

These power supplies frequently fail, and there is little documentation that can assist when trying to repair them.

Scott Wiederhold has done a remarkable job at trying to reverse engineer the GF in order to produce an Open Source replacement controller and his OpenGlow forum contains a lot of photos, teardowns and information.

I have been trying to repair a broken power supply myself, and wanted to combine a bunch of information from various posts, as well as what myself and others found.

Tip

Please contribute here if you can. Any additional or improved information will be greatly appreciated by many.

Caution

This information involves working with lethal voltages (400-22,000 volts) and high power laser radiation! It is intended only for people who are sufficiently experienced in working with high voltage electronics and understand the necessary precautions.
