I just saw your post.
You'll want to start at the beginning.
1) Machine getting power? All 3 phases? Are the fuses good?
2) Does anything happen? Some of the fans run on 120VAC, others on 24VDC. Do any fans run? If the 120V fans run and the 24V ones don't, see #3. 120V wires are red & white twisted together. 24V are blue & grey.
3) If you have power to the machine and nothing runs at all, sounds like the main DC supply. This is a gold box about 6"x3"x12" inside one of the cabinets. Do a search for Hurco DC power supply and you'll find some threads on how to check it, and how to replace it with a PC power supply and an extra 24V power supply (if it's no good).
