[QUOTE=planescott]Thanks Jerry I will put some on. I was told I didn't really need them.
What capacitor would I put on the 640oz/in? What motor is considered large.

Get some Electrolytic capacitors rated at 470 uF. (They have a + and - terminal and are marked). Make sure the capacitors have a rating of at least 75 volts. You can use capacitors rated higher than this voltage.
If you cannot lay your hands on the above value, Any of the below will work.
680 uF at 75 or 100 VDC
1000 uF at 75, 100 V DC
The higher the voltage -- and the value -- The larger the capacitor. So try to stay with the 75 or 100 Volt rating.
In the hobbiest context, I would say 1200 oz/in would be large steppers.
