Hello simpson26,
To answer your questions:
1. Im not sure if you mean that you want multiple GCode Spindles, or if you want another motor to be slaved to the GCode spindle? I believe the 2nd can be accomplished.
- In the Mach4 config, make sure that all motors in question are enabled and properly configured.
- In the plugin config, make sure that all the motors are configured (GCode Spindle too) as indicated in the Mach4 integration manual.
- Go to the motor tab for the other motor, and set the command input index to that of the GCode spindle motor.
- You should have the slave motor mirror the command position of the GCode spindle.
If this isn't what you're looking for, then please explain your requirement in greater detail so I can instruct you accordingly.
2. The axis "letter" for the spindle axis in GCode is the axis where the GCode Spindle motor is mapped to. The GCode spindle must be assigned to an axis in the Mach4 axis mapping in order to receive the corresponding GCode axis command. For instance, if you set Motor5 as the GCode spindle, and you mapped Motor5 as the master motor of Axis C, then a command like "G0C5" will move the GCode spindle motor to 5 units.
