Stepcraft and Materials

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!)
