Machined Parts

The following parts must be machined:

• the twist lock shaft
• the build plate
• the crossbar

Optionally you can machine the these parts for increased rigidity, heat dispersion, and general coolness factor : (STEP files and PDF links below)

• the PDF of the machined motor brackets plans
  • the left motor corner bracket STEP file
  • the right motor corner bracket STEP file

• the PDF of the machined corner plates
  • the left corner pulley bracket STEP file
  • the right corner pulley bracket STEP file

However, some vendors can either machine these parts for you, or they now carry them as a stock part. Note that these parts are already included in the Jubilee Shopping List.

The Twist Lock

The twist lock shaft was modified to be compatible with the specifications presented in the E3D ToolChanger. However, as it has slightly different features because the underlying system operates differently, it is a distinct part.

Purchasing Options

• Joshua Vasquez via Tindie
• SeeMeCNC
• Luke’s Laboratory

The Bed Plate

The bed plate is made from 6.35mm thick MIC6 Aluminum, colloquially known as cast tool plate. This tool plate arrives surfaced, meaning that it is extremely flat to a high degree of specification. MIC6 Aluminum also thermally expands evenly when heated, which means the plate will not warp when heated with a silicone mat as is common for 3D printers.

If you machine the bed plate yourself, you can purchase a 14in. x 14in. x 1/4in. sheet of cast tool plate from Midwest Steel Supply or OnlineMetals. Please refer to the dimensioned drawing for hole features.

The Machined Motor Plates And Corner Brackets

If you machine the motor plates and corner brackets yourself, you can purchase some .25" Aluminum plate from OnlineMetals Or you can purchase them from Mandala Rose works.

• Mandala Rose Works
  • Motor Plates
  • Double Pulley Corners

Purchasing Options

The bed plate can also purchased from one of various vendors either with or without magnets. Magnetic surfaces enable the use of a magnetic spring steel build plate. Non-magnetic surfaces can be made printable with surfaces like glass.

The purchase options are as follows.

• MIC6 Aluminum Bed Plate with Magnets
  • 713Maker
  • SeeMeCNC
• MIC6 Aluminum Plate without Magnets
  • 713Maker.
  • SeeMeCNC

The Crossbar

The crossbar carries the X-axis rail and the tool carriage. The current revision is a pocketed aluminum crossbar, enabling the machine to carry heavier tools and operate at higher temperatures without warping.

• ~160 grams
• Top Speed: 15000 - 20000 mm/min.

Purchasing options

• US Vendor: Mandala Rose Works
• EU Stockist: hightemp3d.com

Depracated crossbar

• Light and stiff. This option was part of the original design, made by requesting a custom DXF from CNCMadness and installing four press-fit composite inserts. Assembly Instructions remain on the wiki.
• ~140 grams + 20 grams with inserts
• Top Speed: 15000 - 20000 mm/min.
