=== Securing the Stock ===
Spoilboard has 1/4”-20 threaded sockets for clamping stock. 3D printed clamps are available for clamping materials up to 1.4" thick.
Clamps:

[[File:FCFL CNC Router Clamp Dimensions.png|thumb|alt=FCFL CNC Router Clamp Dimensions|FCFL CNC Router Clamp Dimensions]]
These can be used in creative configurations to secure your stock.
*Up to ~1.4" stock can be secured.
*Use whatever bolts listed next that work with your configuration.
*Whenever possible, position bolts as close to the clamping area as possible, so clamping force is maximized. Ideally, position the clamp with a downward slope towards the piece being clamped.
*Clamps can be stacked--see photo for ideas.
*Clamps can also be used to butt stock to prevent translation. In this configuration, other clamps need to be used to apply downward force.
*See [[CNC_Router#Replacing_3D_Printed_Clamps|Replacing 3D Printed Clamps]] for the files and print instructions.

WEAR EYE PROTECTION. Wear earmuffs to protect your ears. Make sure hair is tied back and loose sleeves are pulled back.
Lookup the required chip load for your material based on the tool's diameter! You'll need this to be able to calculate proper speeds and feeds.
Spindle speeds typically 7k-18k
Typical feed rate ~200-300ipm.
Calculate feed rate with this formula:
(Feed rate) = (Chip load) x (Number of Flutes) x (Spindle
Match
(Chip load) = (Feed rate) / [(Number of Flutes) x (Spindle
Better to begin at lowest end of recommended feed rate and increase feed up to:

Print settings:
* Position model on its side (bolt direction horizontal to bed)
* Material: PLA+
* 0.8 nozzle
* 0.2 layer height

=== Replacing 3D Printed Dust Collection Boot ===
[[File:Dustboot1.jpg|thumb|alt=Dust boot|FCFL Dust Collection Boot]]
NOTE: This file's geometry tolerances need adjustment (boot groove & magnet holes). It may work on some printers and not on others, so be prepared to modify as needed (either physically or digitally). Holes for the M3 retaining pins were an after-mod, so are not included in the file and need to be manually added later.
This part can be printed as one piece or as two separate pieces.
* Full STL file requires a large printer:
** [https://drive.google.com/file/d/13Dxwsi6C2WWSWrQ5LSA_VqfQnIbXf5Xv/view?usp=sharing CNC Dust Boot Full.stl]
* Separate STL files can be done on any Ultimaker or similar printer:

** [https://drive.google.com/file/d/1wl_y9x7eB8jHbfCK3BMTucW-wmBR_UFu/view?usp=sharing CNC Dust Boot Half B.stl]
Print settings:
* Position model on its back (dust boot grooves facing upward)
* Material: PLA+
* 0.4 nozzle
* 0.15 layer height
* 6 walls
* 12 top & bottom layers
* 30% infill, cubic subdivision
* Generate support everywhere
* Skirt
Hardware:
* [3x] - 1/4" x 1/2" cylinder neodymium magnets
Assembly:
# Super glue the two halves together
# Press in the magnets. The magnets should be about flush and in the same plane as the top surface of the boot.
# Glue the magnets in place.
# Install the brushes. No glue is needed. Will need to modify to fit. Clamp to press in bristles in place.
# Drill holes to allow for M3 retaining "pins" to fit in.
