Overview
These are printed parts for converting an Ender 3 into an electrical discharge (EDM) machine. There are four prints:
- EDM Cartridge Adapter
- Wire to Filament Clip
- X-Axis Cable Management Hub
- X-Axis Limit Switch Cover (Optional)
EDM Cartridge Adapter
The cartridge adapter uses the stock Ender 3 M3 bolts to attach to the X-axis plate. It contains magnets that hold in a EDM electrode cartridge. Cartridges are quick-swap and interchangeable. The cartridge holds the 1/16" brass electrode, which is used for machining. It is a consumable item.
