My CNC Router

<< < (5/6) > >>

vtsteam:
I edited the G-code and dropped the speed down to 8 IPM from 16 IPM. I then changed to a new mill bit I just received in the mail today. Also inexpensive (5 for $20) but speced for aluminum. The others were supposedly for stainless steel (!) but they did seem to work well on aluminum on the Bosch Colt router.

Anyway, I ran the same part again with the reduced travel speed, and it cut. Looks like a decent job. Not as fast as the router, but this also was a different offcut of aluminum, and might have been a different type.

I'd say the 500 watt spindle is usable, though slower. Definitely quieter, which is a plus. Also it is DC and can be speed controlled from LinucxCNC if I figure out how to do that.

Here's the results of both the first (bottom) and second attempt:

Just sent you a PM...

Joules:
Steve, where do you get those fancy cutters that can do draft angles as in your photo ???

vtsteam:
Little known fact Joules. An ordinary screwdriver can serve as a milling cutter.

Joules:
Using a milling cutter to drive in wood screws leaves them tamper proof 🤪
