It is a 3-axis CNC hobby milling machine, basically a Colinbus Profiler bought through Elektor.
I bought it as a kit, Building a machine from scratch would have been awesome but as I live in an apartment, I have no proper workshop and limited tool and materials assortment, so I opted for the more-expensive-but-easy-way.
Basic characteristics:
- 300 x 400 x 100 mm effective travel
- Guided by special ball bearings on steel round bars
- 3 small stepper motors
- Trapezoidal lead screws with special nylon nuts (no backlash)
- Integrated electronics
- MDF base table
- All made out of aluminum and steel.
That's about how the Profiler looks like at the step "out-of-the-box + x" (in my case, x means a crapton of hours of assembly)
