First cut
The current instruction for making a first cut.
Build
Plans for a 2-axis wire machine.
BaxEDM publishes the CAD, the water schematic, the cabinet wiring and the bill of materials used for its own MK3-style wire machine with the BX18. The first-cut instructions are the place to start once the machine exists.
MK3 CAD
Model of the MK3 machine.
Water schematic
MK3 water system.
Cabinet wiring
2D wire machine, three pumps, BX18 and C-Arc.
Lathe axis
An EDM lathe axis that mounts on the work surface of a wire machine. Also written up on Hackaday.

This is the published European-sourced list. Distributor links go stale; the part numbers are the useful half. An earlier MK2 draft is still on the page index.
Rainbird 100-HV valves. They are sold for 24 V AC. This cabinet has no 24 V AC supply. Drive them at 12 V DC. Do not use 24 V DC. That will damage them.
