"Real" Stepper motors about astroeq HOT 5 CLOSED

Bipolar 1.8 degree stepper motors (200 step per rev) are fine. Depending on the ratio of the telescope worm gear, there are certain gear ratios between the motor and worm which (in theory) result in very little error - I've seen one combination which calculates to 0.0003 seconds drift per day when tracking.
For a 144:1 worm ratio, the following two are near ideal gear ratios:

2.6666666:1 [40:15 is what I used]
4.5:1

Super, my Worm is 144:1.

I have 2 types of stepper motors 5v and 0-48v, how much power does AstroEQ supply to the current motors 6v or 12v? Or better yet how many volts can I supply by adjusting the Pot's on the Motor Controller?

It's not the voltage that matters, its the current. It's perfectly save to run a 4V stepper motor at 12V - you can even run them as high as 30V without any issue.
As long as the rated current of the motors is less than 1.2A per coil, they are compatible. Ideally you want the higher current, low voltage motors as you can get higher torque - the lower the rated voltage the better.

As an example my motors are rated at 1A, 2.3V. It is perfectly fine to drive them at 1A, 12V.

The potentiometers on the motor controllers don't adjust the voltage to the motors, they control how much current can flow. The drivers use the coils of motors as a form of transformer to limit the current that flows. In fact you want the voltage applied to be as high as possible to reduce the loss of torque at high speeds.

When I use the stepper motors, do I need to change the Driver Chip in the Config Utility and enable 1/16 Microstepping? I hooked one of the 5V motors to the RA output to test it using the same Values for my current EQ5 motors (15°, 300:1, 144:1) and it wouldn't track. It would pulse back and forth 1 step. I could slew it at about 70x but it had no Tourque, I could stop it with 2 fingers.

Using you old values for the new motor won't really achieve anything useful. You need to enter the correct values for the new motors.
For the 1.8* motors with a low gear ratio (like 4.5 or 2.66666) you will want to enable micro stepping to get better accuracy in tracking speeds.
