Here is mine:
Drivers:
KL-8056D
PSU:
48 volt Toroidial
Breakout board:
C11T Also recommend
PMDX 126 (I will be using this on my Hurco build)
Steppers: 640oz NEMA34 on lathe Z and 425oz NEMA 23 on the other 2
Lathe motor:
1hp 3 phase 1800 rpm
VFD drive:
GS2
Certainly only my opinion but they all seem to work very well. I removed all gears from spindle and made a new pulley from scratch. You will need a way to oil bearings and the way I did it may not be the way to go. As for mill it's still running stock motor and will be removed completely when my Hurco is done. The mill head has way to much play to achieve any decent finish....let alone lack of RPM. I just hacked a stepper on the adj knob and weld gears to remove some play. It works BUT........
I would think a premade Z assembly like for a router would work pretty good fastened to front of mill head. Very happy with my lathe and have tons of hours on it.
Hope this helps a little and I'm sure others will post there list.
