Project NiCr: CNC Hot Wire Foam Cutter

NiCr is an open source and open hardware project that aims to create an inexpensive, do-it-yourself proof CNC Hot Wire Foam Cutter. It is heavily related to FreeCAD through a custom workbench.

Sheet Metal Workbench

Current state: development stopped until the complete release of the NiCr
project. However, ideas and support are welcome.

Update 1                                          A collection of scripts (with video!)

Update 2                                          A real workbench and sheet metal part

Update 3                                          Complexity starts here: Bend along axis

 In process  (unhurriedly)

- Sheet Metal ---- 60%     Basic workbench functionality achieved (fighting an epic war against topological naming)

- Hot wire foam cutter ---- 10%

Possible ones:

- Simple structure solver (see cype)

- Ergonomics module
