Zen CNC
After some searching, debating and comparison we have decided to spend our 500 Euro budget on the Zen toolworks 7x7 CNC.
our machine with test setup:

First tests with pen and 1mm drill as cutting tool:

First Actual PCB drilling:
Who
Goal
- CNC machine voor minstens XY as
- minder dan 500 Euro aan onderdelen
- kop: Dremel boor of extrudeer machine monteerbaar
- suitable for PCB-milling
Electronics
From many electronics options we have chosen to make reprap Generation 7 Electronics. It can drive 4 stepper motors (XYZ and one Extruder), is easy to build, uses common pololu stepper drivers and has many options including electronics for contolling heaters, endstops etc.
The finished electronics (parts for 3D printer left out):
Firmware
Currently we are testing with Teacup Firmware which is supposed to also work for CNC-milling. but the firmware lacks Arc support in Gcode so we might have to switch to Marlin or grbl.
Cad / Cam and other software
We are testing some software for different purposes:
- Printrun, a utility to control steppers manualy and send gcode to machine
- ReplicatorG, an open source 3D printing program, also with gui to controll the steppers manualy
- GcodeTools plugin for Inkscape so we can use inkscape designs
- pcb-gcode plugin for Eagle for use with pcb milling
Free 3D Modeling Software
- Google SketchUp (requires the freeware plugin to export STL)
- Blender (GPL)
- Art of Illusion (GPL)
- TopMod3D (GPL)
- Wings3D (GPL)
- StructureSynth (GPL)
- OpenSCAD (GPL)
- Heekscad
- FreeCAD

List of add ons and options for use with the CNC
- dremel flex shaft mount Peter has designed and printed a similar set of mounts but the flexible dremel shaft was a little bit too flexible. A new design was made and printed by Peter so the dremel is now mounted at the CNC directly.
