==Changing out an End Mill==

#First ensure power is off to the spindle motor. You should keep the ShopBot tower on though to ensure that the gantry will not move as you change out the end mill.
#Remove the dust-collector hood. It is held on with magnets.
#Use the two wrenches by the desk (picture) to turn the bottom nut (counter-clockwise/clockwise -need to check).
#Remove the end mill and place it with the other end mills on the shelf above the spindle motor controller.
#Insert your end mill and tighten down the nuts. Ensure that the nuts have tightened down the end mill and have not just tightened to each other.
#Put dust collector hood back on.
