Single axis electrical discharge machine ( EDM )

Hi,

After building this big CNC router in the past I decided to move on.

And that's how this bad boy came to life:

It is a highly customizable single axis, "mostly 3D printed" sinker EDM with a custom software and touchscreen.

It has many options to fine tune the process.


It currently runs on a single ESP32 but this may change to a quad-core NanoPi Neo to support 4 axis later. Also a wire EDM module will be added after the final design for the X and Y xis is done.


The final control panel will look different from what is shown in the video. The PSU for the steppers will be included in the 19" rack later.

The project is now on kickstarter if anyone is interested:

Just a small update.

A lot of time has passed and a lot of things have change. The single axis sinker EDM is now a fully 3 axis EDM CNC that can do sinker EDM, EDM engraving, Drilling and also Wire EDM.

So much has changed. New software, new sensing, new Controlpanel and also the mechanics itself has changed.
