The ShopBots are our standard CNC Routers, used to cut 2.5D or 3D shapes out of wood or plastics.
MakerSpace Safety Orientation and ShopBot CNC Router Training are required to use this machine. Visit our Training Page to learn more.
It is recommended that you learn and get comfortable using the Othermill before using the ShopBot.

Software
Fusion 360 (Recommended for generating toolpaths from 3D geometry)
PartWorks (Similar to VCarve, used for creating toolpaths from vectors or bitmaps)
PartWorks3D (Similar to Cut3D, used for creating toolpaths from .STLs)
ShopBot 3 (Used to run ShopBot Part files, similar to GCode)

Nominal Cutting Area (X ⋅ Y ⋅ Z)
ShopBot Desktop - 24" x 18" x 3.5" (610mm x 460mm x 89mm)
ShopBot Buddy - 24" x 32" x 5" (610mm x 813mm x 127mm)

Allowed Materials
(You must bring your own material to cut on the ShopBot)
Plywood
MDF (Medium Density Fiberboard)
Softwoods
Hardwoods
Soft Plastics
Hard Plastics

Available Cutting Tools
1/2" 90° V Bit
1/8" Upcut Ball Nose
1/4" Upcut Super "O"
1/4" Downcut
1/16" Tapered Ball Nose
1/2" Two Flute Straight V Flute
1/8" Straight "O" Flute
If you provide your own bit, it must have a 1/4" or 1/8" shank and should be designed for use with a CNC Router.

Feeds & Speeds
Spindle RPM (speed) and tool movement (feedrate) should be chosen carefully based on the tool used and material to be cut. If you're using MakerSpace cutting bits, a tool library is available for Fusion 360 below, which includes reasonable values. The same tools are available in PartWorks. Check that the pass depth (AKA maximum roughing stepdown, multiple depths, etc) is set to no more than the radius of the tool.

Fusion 360 Tool Library
These include tools available in the MakerSpace, and are programmed with feeds and speeds already. Be aware these speeds may need to be adjusted based on the actual composition of the material being cut.
These can be imported into Fusion by right clicking on the 'Local' tool library -> Import Tool Library, or: How to import a cloud tool library
