The dust collector shoe swings out of the way for easy bit changes and provides good cut visibility.

• Loosen the ...top (3/22) knob and swing the shoe out of the way
  
• Insert/tighten the bit and set its start location/height
  
• Turn on the CNC controller to lock the stepper motors
  
• Swing the shoe over the bit until the bit is centered in the hole/shoe
  
• Set the shoe plate just high enough to clear all clamps/screw heads.
  
• Insure that the space between the router body and shoe is >= depth of cut.
  
• Tighten the top knob.

In the example the shoe is relatively high because it needs to clear the knobs (bad idea), luckily there was enough clearance to make the desired depth of cut... There are some new low profile hold down clamps to help with potential clearance issues... Added a rotational stop to simplify bit/shoe plate alignment... Widened the bit slot for the 1/2" V bits, even the collet nut will fit when the flats align with the slot.
