First, I apolgize, I do have the line:
#define STRING_CONFIG_H_AUTHOR “(V1 Engineering, Ryan, 510S)”
Second, I do wish to only turn the spindle on and off with no speed control. So I just tried connecting to the two pin header directly adjacent the X stepper motor driver and it seems that is always actively high no matter what command i send. The spindle comes on and stays on. Do i need to change the firmware for this fan header in any manner?
