# HAL config file for vismach simulation of vertical milling machine
# This file deomstrates closed-loop spindle control in both position and 
# Velocity modes.

# Note that the connections of the signals to "hardware" are all in the 
# sim_vmc.hal file rather than here

# the same time as the Axis PID components
