Some of my 3D reliefs in wood.

Wood carvings in diy cnc, some reliefs take 9-11hours to complete at 3500mm/min (137 inch/min).

Great job! May I ask how long it takes usually to complete one project?

Hi, depend of what project.

For example with old stepper motors nema 23  the skull girl take 9hours at 3500mm/min XY and 1200 Z and the skull 4 hours aprox (only 3D finishing roughing passes are 3 and 1:30 hours).

With new motors (nema 24 closed loop hybrid), i finished to wiring new control box with csmio, closed hybrid motors nema24 and spindle with 50-75% more power (from kress fme router to teknomotor 1.1Kw spindle) i want to try to make it at 3500-4000mm/min XY and 2000-2400Z (maybe the tapered ball nose bit doesn't have enough resistance, but i need to try it because if i double Z speed its a lot of time of machining 30-50% depending of accelerations i think).

Whenever you had coordinated motion which includes Z axis, your max speed would be 1200 mm/min, regardless of commanded 3500 mm/min. Coordinated motion is as fast as the slowest axis.

I never noticed it, i thinking X,Y moved in full speed when no Z movement are involved.

In next try of 3D relieve i want to try the limits of the tapered ball nose bit and try double the speed or more.
