* For the M0-M2 configuration, set is low when no jumper connected and high when jumper connected, check on A4988 board configuration for this.<br />
* A.STP and A.DIR is to copy/clone the motor setting from X, Y or Z axis to the fourth motor if you have.<br />

== Software ==<br />
=== GRBL Firmware ===<br />
GRBL is opensource software that runs on an Arduino Uno that takes G-Code commands via Serial and turns the commands into motor signals.<br /><br />
<br />
[https://github.com/grbl/grbl The GRBL source Code is located here.]<br />
<br />
<br />
=== Compiled Firmware HEX ===<br />
* Upload using Xloader [[AVR Programmer]]<br />
* Version 0.9 - [[File:GRBL_coreXY_Servo_draw.zip]]<br />
* Version 1.1 - [[File:V1.1_GRBL_coreXY_servo_servo_small_angle.zip]]<br />
<br />
=== First Run Debugging ===<br />
* Check all the solderings to make sure all soldered well<br />
* Adjust A4988 breakout board when necessary, and carefully install the A4988 driver board<br />
* Connect external power to power up<br />
* upload arduino firmware and test communication via serial port for gbrl, send demo G-code for testing all four axis.<br />
