In order to give an overview on my experience with the stepcraft cnc, I’d like to share my experiences with different materials.
(Updates planned in the future)
Best Results:
- PVC dry (Endmill ≥ 3mm)
- PMMA dry (Endmill ≥ 3mm)
- PMMA in water (Endmill < 3mm or longer roughing)
- CFK in water (Specialized endmill 1mm)
- Aluminium EN AW 2007 (AlCuMnPb)
- Brass MS58 (CuZn39Pb3)
Good Results (Some issues finding the best setting, a few broken endmills):
- Aluminium EN AW 5754 (AlMg3)
- Aluminium EN AW 7075 (AlZnMgCu1,5)
Moderate Results (Difficult to find optimal settings, loss of more than just a few endmill):
- Non jet, but I still have quite different materials on stock…
Heavy loss or not machineable:
- I expect this for mild steel and simmilar materials (I do not intend to try!)
