Description:

CNC equipment for a retrofit on a RF45 mill OR similar machine form Grizzly or busybee OR your own CNC router OR Lathe.

1x nema 34 stepper ( 1290 oz in 3.1V 6.3A 5.5mH inductance 4 wire )
Both of the above have spec chart and test certificate / torque and speed curve tests.
1x small nema 23 stepper ( 8 wire 2V 7A unknown torque - Plenty good for a 4th axis conversion )
1 small and 2 large cooling fans designed to go inside the electronics enclosure
3x CPU heat sink fan designed to mount the the gecko drivers for proper cooling

Various small heat sinks
small 1 amp variable voltage PSU or fixed 12V ( AC input DC output ) Designed to run the geckos.
1x digital amp meter
1x digital volt meter
Both of the above designed to monitor the toroidal drain and health with in the electronics enclosure.
Antek AN-8450 toroidal cap bank diode rectifier, Perfect match for the geckos and the 3 steppers. All ready calculated the best of both worlds including line drop or surge max running voltage etc etc etc. http://www.antekinc.com/details.php?p=131
Just solder up the caps and attach to the diode bridge. Whala!
1x pulse gen made by Dan Mach - Handy to test out potential steppers or to make a simple power feed, Can be wired to a PC and commanded to function VIA mach3.

3x .625" ball screws - designed for an RF45 conversion or similar mill drill, Extra length on each for personal fit and machining.
6x preloaded ball nuts. Designed to be used in pairs with the springs shown in the picture to PROPERLY achieve 50-75 lb preload on the nuts = zero lash!
1x radial bearing on free float end and 3x angular contact bearing blocks.

4x flexi couplers from steppers to ball screw.

Like I said a complete package for a cnc conversion or used on similar plans or ideas, I will share all my plans or drawings or insight on what you plan to do. My sale is not final.........Comes with virtually unlimited support - Will even drop by if some one local grabs it.
Check on ebay what a 1200ozin nema 34 stepper costs.........
