Oh yes, I now understand. Nagulat lang ako kasi inabot ng 3 hours ang front face pa lang. It must be that extensive.
That was one of my goals before when I built my CNC. But now, I sometimes mill circuit boards for hours din sir, time is a factor in the quality of work kasi.
Some would say... "bakit ka pa nag CNC kung matagal din pala?"
The simplest answer is precision, and it's a repeatable process too.
Ang sagot ko nga minsan... "sige subukan mo mag etch ng mano-mano na 0.5mm pitch..."
Besides, you can do other things while the CNC is working like read FHM magazines etc...
