I think you are right. That is pretty good.

I think I get a D for effort...

Does the material make a difference? Really nice, thank you for posting.

Proobably mostly depends on the the tool shape, stiffness and machine rigidity.. (and spindle torque at low rpm)

I sure love seeing it cut, what motors and drivers do you have with your CNC?

This is a tormach 440 sized mill I got for doing some work. (it was literally tormach's prototype. Thank goodness they didn't go with this supplier..) It had a lot of fit and finish issues.

So the steppers are what would be on the 440 and a leadshine mx3660 runs them. The spindle is a 750w iirc brushless that I am running with a stmbl drive. (open source swiss army knife of servo drives)

Thanks! I have a riser for my 8520 on my todo list. Besides motorized XYZ.
