Tool for easier working and more Testing

A project log for Sinker EDM Machine

Like a hole puncher, but for metals. For your shelf or desktop.

Over the last few days I wrote some code for makeing it easier to place multiple drilling locations next to each other (easier than writing the whole gcode per hand).

GitHub - DerM4209/Pixel_EDM

And with the GCODE created by the tool I did another test:


This time I cut out a small bracket. The cut took around an hour with no need for observation or intervention while machining. I think workpieces like this can be cut to do actually useful things with the machine. So the good things are that the machine is now working reliable and also quite precise. The problems remaining are that the machining takes quite long and the DI filter and electrode need to be replaced after some time. The machining time can be reduced by using a more powerfull PSU, but the need for replacement of the DI filter + electrode will remain.

So for now I think this is the best result that I can get with my EDM machine.

I will also look into ECM and other machining methods in the future.
