Step 2: Steel Track Brackets

Photos in this step show Acrylic brackets, but installation is identical for the Steel brackets.

The track brackets are for mounting the boot to the 

stock X/Z Carriage on your Shapeoko CNC.   

You'll need an M5 hex key for this step. (not included)

  • Remove the two right side screws from the top of your CNC machine; leave the belt cover in place.
  • Put one of the supplied screws into the top hole on one of the track brackets then slide the spacer on to it... next insert into one of the holes and tighten down.
  • Install a second screw through the bracket, through the spacer, and into the bottom hole.

Tip 1:  Install one bracket at a time so your belt-cover plate doesn't have to move much.

Tip 2:  In the second photo below, I'm demonstrating the slight gap between the bracket and the router mount.  This way the bracket doesn't interfere with the z-axis movement.

Step 3: Support Arms

In the box you'll find two support brackets with screws and plates.

No tools are required for this step.

  • Insert thumb screw into support arm
  • Hold plate behind track bracket
  • Secure plate and screw by screwing them together with the acrylic bracket in between.

Required: If you have steel brackets, I've included two extra M4 nuts to use as a spacer on each thumb screw.   See last photo.

Tip:  When setting up for cuts, you can loosen the thumb screw just enough for the support arm to slide along the bracket without removing it completely.  This allows you to adjust the height of the boot to fit your needs of each cut.

Note:  You may need to take a metal file to the piece of the support arm that fits into the acrylic track.  Doing so will help the support arm to slide up/down the acrylic track bracket.


Step 4: Attach Boot

This is a step you'll be repeating often and is extremely easy to do.

  • Position both support arms about 1.5" above your work surface.
  • From behind the X gantry, slide the boot into the magnetic support arms.

Tip 1:  The magnets will do most of the work, thus very little force is required to properly seat the boot.

Tip 2:   It is handy to gently squeeze both support arms together to ensure the boot is fully seated.

Tip 3:  If you need to adjust the position of the boot within the support arms, you'll need an M3 hex key.  Loosen the two screws on each side wing slightly and adjust as needed.

Notice:  If you have the Steel Track Brackets, you'll need to offset both wings by 3mm.  This will properly align your spindle. 

(See last photo below.) . 


Step 5: Attach Dust Collection

The boot is useless without a dust collection system... 

  • From behind the X gantry and the boot... attach the adapter to your dust collection hose.
  • Slide hose/adapter into the boot.
  • Ensure the hose is loose and has enough slack to reach the extremes of your setup.

Tip 1:  Hold the boot with one hand and the hose/adapter with the other.  Gently push them together until they're well seated.

Tip 2: If the included hose adapter doesn't fit your collector, reach out to us at info@pwncnc.com to see how we can help.

Tip 3:  I'm told the adapter is a tight fit for common flex hoses, especially in the winter.  You may need to take a hair dryer to your hose in order to properly insert the adapter.


Step 6: Attaching Face Shield

This step is completely optional.

The face, although different shapes, 

attaches to the boot v1 and v2 the same way.

  • Slide the two protruding screws on the face shield into the corresponding holes on the front of the dust boot. 
  • Allow the magnets to catch and pull the face shield into a fully seated position.

Tip:  Leaving the face shield off gives your filming equipment the perfect clean view while cutting.

Warning:  I am aware of an issue in which the face can tilt upwards when moving across high profile clamps.  The face does not come off when this happens, only tilt upwards and back down when the clamp has passed.  Consider switching to a low profile clamping system.
