Detailed ZYLtech CNC Shield Instructions, including “First Run”, Current Limit Adjustment for Stepper Driver, Jumper Settings, and Motor Wiring.
This is a quick guide to help with assembling the Arduino CNC Shield V3.XX. We also have a discussion forum for this board : http://forum.protoneer.co.nz/viewforum.php?f=6 Contents: First step is to solder the Power Wire( or Fuse) and 10K (R1) resistor in place. (Version 3.03 and on does not need the Power Wire anymore.)
Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others)
The A4988 is a microstepping driver for controlling bipolar stepper motors which has built-in translator for easy operation.
Microstepping can divide a motor’s basic step up to 256 times. Microstepping improves low speed smoothness and minimizes low speed resonance effects.
Microstepping produces roughly 30% less torque than dual phase full stepping
