HEDMA is a hackable homemade EDM[1] machine.
Documentation is in the FabricateEDM[2] repository.
Innhold
Maskin / Machine
The machine is homemade, using existing machines and parts.
Motion platform
The motion platform is a Ultimaker 1[3] 3D printer.
Controller
We have replaced the original controller with an OpenBuilds Blackbox[4], and use an OpenBuilds Interface[5]
Power supply
We are using the Powercore V1. Manual[6], hardware[7], firmware[8].
Programware / software
EDMWeb[9] is the CAM software used.
Sikkerhet / safety
- do not touch when running
- stop cutting if a short occurs
- run only with dielectric fluid in the bath
Bruk / usage
The powercore guys made a nice video: Powercore V1 Quickstart Guide[10].
You need to have a dielectric fluid in the bath, de-ionized water is good. The workpiece is connected to the anode (positive side) and the tool to the cathode (negative side).
Plassering / location
The machine lives in a corner of the printer room.
Historikk / History
- 2024-03-20
- tested with titanium (0.5 mm) but we had limited success, because our minimum feedrate (both plunging and X / Y moves) was too high. This seems to be a limitation of the controller.
