Progress update G-EDM EVO2
3 days ago • 0 commentsThe new machine is almost ready for the first tests. It still lacks a z-axis but for wire EDM it is not needed.
A functional Z-axis does make life easier but the code can run without too.
The fittings to connect the filter hoses are placed at the front of the tank. This way the tank can be removed easily and the machine can then be used as wood mill.
A "little" nozzle can be adjusted to change the direction of the water flow into the tank.
And another future upgrade will be a pulseboard that has the new sensor circuit integrated and some other improvements.

G-EDM EVO2 meets PicoEDM wire extension
03/24/2024 at 02:09 • 0 commentsThe G-EDM Tower was initially designed as a single axis sinker EDM and now with multi axis support it is time to refresh it.
A little Gantry CNC router using the PicoEDM wire extension. Evolution never stops.
For more details about the PicoEDM see: https://github.com/alextreseder/picoEDM
The G-EDM EVO2 is a medium duty high gantry router design that takes care of future upgrades for normal milling operation.
A RO-Filter system is mounted on the back of the machine and the water hoses will be routed through the profile into the tank to make them almost invisible.

New PCBs, new sensing unit
03/08/2024 at 17:17 • 0 commentsThe new sensing unit finally evolved from a breadboard prototype to a nice and shiny PCB.
The feedback works nice and sensitive. It is able to capture the raw water contact too. and reacts to tiny single discharges.
I won't go into details about the parts but the board offers a fully isolated high side shunt current feedback. A linear optocoupler is used for isolation. The ESP is now fully disconnected from the pulseboard.
PS: Thanks to PCBway for the extra boards.
