BUILD.md walks through the whole build: what to buy (parts and screws), the
v3 print list with materials and supports, case, electronics (microstep
jumpers, driver current), centre, the arm on the bench, hub and slip ring,
wiring to the CNC shield, software setup and a first run without sand, then
floor, magnet height, sand and glass, plus troubleshooting.
Also adds the 608 fit test to print/v3 so the v3 folder is complete.
