For me personally doing 3D carvings, the Z axis is where I would really like to boost things if at all possible. Every line of gcode for the 3D carvings is at a different Z height, so I’m limited to the speed of Z for all cutting. The bit’s tip is 0.5mm and 1mm with stepovers of 20% and under so even at 30mm/s Z speed I have some stuff that takes over 16 hours. What do you think has more bang for the buck – going from 12V to 24V or going up to a larger Z motor – to improve Z speed above 30mm/s?
