Bought a G0704 a few months ago... In the process of doing a CNC conversion on it.

The plan.

- hiwin linear rails on Z axis
- 2 inch head & column spacer
- 1hp 3 phase 56c motor
- belt drive
- double nut ball screws
- oil system for ways
- grease system for screws
-power draw-bar (air over hydraulic)
- flood coolant

Electronics.

- Mach 4
- intel NUC
- ESS smoothstepper
- mx3660 driver
- 48v 12.5amp power supply
- nema 23 570oz stepper (x/y)
- nema 34 906oz stepper (z)
- hitachi VFD (modbus)




Fresh off the boat....


The hiwin linear rails where the first task to be tackled. 15mm CA preload. Milled off the dovetails in the kneemill. Turned out really great.....
