The 64 general purpose output signals can be controlled from gcode using the mcodes M220 and M221. The gcode
can wait on one of the 64 general purpose inputs to be a certain state with mcode M222. For more information, refer
to the
Mach4 Advanced M-Code Reference
manual.
The following instructions are for configuring a servo spindle as the main spindle on the machine. Some machines, such
as centerless grinders, may be using a servo spindle as an auxiliary spindle or subspindle. See
