My bed mill has the spindle driven by a dc brush servo motor, this is because the spindle motor is also used to rotate the tool magazine in case of a tool change.
As the servo drive accepts step/dir commands only, similar to a stepper drive, I can't use the spindle interface of the 7i76e mesa card but will have to use a encoder output and configure the spindle as Axis_A and Joint_3 as TYPE = ANGULAR. However, as I don't find any example, I don't know what exact parameters I need to configure for this special case and how to make linuxcnc recognize it as the spindle. Has anyone done it?
