CNC STEPPER MOTORS
Which wire is Phase A, A--, B, B--?
This has been explained in a current Wiki article.

CNC DRIVER CARDS
How can I use one power source for both power jacks on the Univelop TB6560?
This will be updated as soon as I have confirmed a few necessary details.
MACH3 SOFTWARE
How do I figure out the "Steps Per" in the Mach3 configuration?
This value is a multiplication of a few other settings:
1. First, figure out the Steps per Revolution [SPR]:
- The Nema motors are angled at 1.8 degrees so divide the circumference by the angle
- 360 / 1.8 = 200 steps per revolution
2. Now we need the Revolutions/Turns per Unit [TPI]:
- Our lead screws are pitched at 1.25mm per revolution which results in 20.32 revolutions per inch.
3. Find out the Resolution Support (microsteps) of the driver card:
- Most cards support up to 1/16 (16 microsteps per step)
- TB6560 supports the "Full" step as well as 1/2, 1/8, and 1/16 steps
To get the Full Steps per Unit, multiply StepsPerRev x TPI:
200 x 20 = 4000 steps per unit
To get the Micro-Steps per Unit multiply StepsPerRev x Micro-steps x TPI:
200 x 16 x 20 = 64,000 steps per unit
