## 👁️ About
[**Fabex CNC CAM extension for Blender**](https://blendercam.com/) is an open source solution for artistic, personal, commercial or industrial CAM - Computer aided machining - a g-code generation tool.  It was called Blendercam but the name Blender can no longer be used in the name due to Trademark.


It has been used for many milling projects _(artistic, personal, commercial and industrial)_ since its creation in 2012, and is actively developed.

## 👌 Features

| Feature | Description | Status |
| :---: | :--- | :---: | 
| 2D & 3D Milling Strategies | _Profile, Pocket, Drill, Parallel, Cross, Block, Spiral, Medial Axis and more_ | ✅ |
| Cutter Types | _Ballnose, Ballcone, Bullnose, Flat Endmill, V-Carve, User Defined and more_ | ✅ |
| 3D Data or 2D Images | _Model in Blender, or import any 3D object or Black & White image, and generate toolpaths_ | ✅ |
| Layers & Skin | _Leave material during Roughing to ensure that your Finishing passes have enough to work with_ | ✅ |
| Inverse Milling | _Cut an inverted piece for joinery, e.g. Male to Female connector_ | ✅ |
| Ambient Around Model | _Restrict Cutter to specified radius around the model_ | ✅ |
| Protect Vertical Surfaces | _Cutter moves vertically next to surfaces greater than a threshold angle_ | ✅ |
| Stay Low | _Keeps the Cutter low, if possible, to reduce travel time_ | ✅ |
| Stock Material Setup | _Enter material dimensions & location, or get them from your 3D model_ | ✅ |
| Operation Simulations | _Use your toolpaths to generate a 3D mesh simulation of your finished product_ | ✅ |
| Arc Retract | _Retracts cutter in an arc, rather than straight lines to reduce travel time_ | ✅ |
| Pack Curves | _Auto-arrange all selected curves to fit on a plywood sheet for easy bulk cutting_ | ✅ |
| Slice Model | _Vertically slices model into a series of curves to be cut and stacked to recreate the 3D shape_ | ✅ |
| Automatic Bridges / Tabs | _One click to add Bridges/Tabs to keep your work in place during Cutout Operations_ | ✅ |
| Chain Operations | _Combine multiple CAM operations into a Chain, Export as Gcode, or create a Chain Simulation_ | ✅ |
| Adaptive Milling Speed | _Adjusts the operation feedrate relative to the chipload calculation_ | ✅ |
| :warning: Helix Entry :warning: | _EXPERIMENTAL - Available in the Extension, but not yet fully supported_ | ⏳ |
| :warning: Ramp Down :warning: | _EXPERIMENTAL - Available in the Extension, but not yet fully supported_ | ⏳ |
| :warning: 4 Axis Milling :warning: | _Currently only possible via manual indexing_ | ⏳ |
| :warning: 5 axis Milling :warning: | _Currently only possible via manual indexing_ | ⏳ |
