Technology

The CNC milling machine

The spindle has an output of 2.5 kW and has a vacuum table with which you can easily attach panel material. It is controlled via Buildbotics.

Materials

In addition to various wood materials (MDF, plywood, solid wood, HDF), acrylic and other plastics can also be processed.

⚠️ We have decided to stop milling aluminum on our CNC. It was too complicated because we always had to modify a few things (extraction system) and the low demand didn't justify the effort or the risk.

We have a well-stocked materials warehouse with offcuts of various types of wood that are freely available. We can also have material delivered directly to the workshop via 2 timber dealers.

It is important that the board is flat and at least 0.1m² in size, otherwise it will not hold on the vacuum table. If your material is too small, you can also attach it to a support plate (screw, glue).

Milling cutter

As standard, the router is operated with a 6 mm wood router bit (maximum plunge depth 21 mm), which is suitable for wood-based materials such as plywood/chipboard or solid wood.

You can find an overview of the other available cutters in this table:

In addition, we also maintain milling cutter databases for Autodesk Fusion, which contain the most important milling cutters together with their cutting data (presets). You can find these in our Github: https://github.com/konglomerat/sailormoon-cnc/tree/main/tool_libaries/Fusion

⚠️ The milling cutters may only be used, changed and calibrated after instruction because there are a number of things to consider here.

If you don't want to get into CNC technology yourself or the 6mm wood router is not enough for your project, there is also the option of having a member of the CNC team support you with your project.

File formats

To produce a milled object from your project, your drawing must be transferred to Fusion360 or VCarve, VCarve can be obtained free of charge from the conglomerate. If you want to use another CAD program or graphics program, all layers must be exported as .dxf/.dwg/.eps/.ai/.skp/.svg files and can then be imported into VCarve or Fusion360.

Recommended programs

To create the milling files:

Vector graphics and CAD programs:

  • OnShape: browser-based, free 3D CAD tool. Strongly oriented towards SolidWorks
  • SolidEdge2D free: free 2D CAD tool from Siemens
  • SketchUp free: free 3D graphics tool
  • Inkscape: free, open source program for creating vector graphics
  • Illustrator: program for creating vector graphics, part of the Adobe CreativeSuite

We use Buildbotics as our CNC controller.

Requests

If you would like to have something milled, please be sure to send your files with your request. These should either be vector graphics, 3D designs or finished G-code. If you are not sure, please send us your current status anyway so that we can give you feedback!

Vector graphics

Preferably in Illustrator format (.ai),

alternatively as pdf or svg

Please always make sure that the shapes are filled (i.e. consist of closed lines)

3D designs

Ideally as a Fusion 360 design file, as we are currently using this software to create the milling program. Alternatively, STEP or similar can also be used.

G-Code

Please also bring the raw data in case we need to make any adjustments on site.
