Hey guys, Im in the process of converting my mill, Im almost complete actually.
What I have is:
Homier mini mill
Gecko 201s
Japan Servo KP86SM2-002 Stepping Motor
2.35 VDC, 1.8 Degrees/Step
They are bipolar 2.5V @ 4.1 Amps
A power supply I made:
24v(12-0-12) transformer(1 or 2) 80v max 18,000uF capacitor, and bridge rectifiers.
At 24v I get around 30v after capacitated, at 36v I get 56v max after capacitor, Im affraid of even hooking up total 48v to it because my cap may 'splode. I really wanted to run these at 48v but Ill have to get another capacitor with a higher maximum and a voltage regulator.
So right now I have the 24v hooked up because 56v is close to the absolute maximum of my motors.
The motors are rated at 4.1A but I was told to run them at 2A because thats not over 67% of the rating. Should I have it at 3 or even 4amps?(set on my gecko 201s)
Heres some pictures of where Im at:

Heres a short video, dont download it too many times, I might be short on bandwith.

*note* Yes I realize the Y is backwards
Also I have a pully set I got made up, maximum of 9000rpm, I took the bottom bearing and spindle out of the head, and didnt have a flange to take the top bearing out without killing it, and to put it all back together I'll need to get ahold of a boaring bar and make some when I get my lathe unless someone else has another idea or could help me out with that.
Let me knwo what I should do,
Thanx
Jon
