Re: [CAD_CAM_EDM_DRO] Machineable wax problem

I'd recommend using a HARD machinable wax rather than the wax you normally
use for jewelry work. Another option (recommended) would be to carve in
some other material, make a mold from the carving and then cast a pattern
from low temp wax to use in your lost wax casting process.
