Controlling 6 stepper motors and 2 spindles on a budget

[Boyan Silyavski]

It all depends what size are the steppers and what speed they will move at. The 3d printing board are super slow / at least to our standard :-) here/ , but if motors are nema17 this way is better as the drives are cheap and plug and play in the board. But "spindle" and "nema17" are not words to be used in one sentence. So What Dean says is much better

Our steppers are Nema 34 on the x,y plane and Nema 23 planetary geared motors on the z. We need to achieve 3.14 KW on our spindle. We thought of buying a 3KW spindle but as this is expensive we are thinking of using the gear to adjust the power for a less powerful spindle. Spindle needs a minimum of 1000 rpm, the steppers need 104.7rad/s basically all motors are going at 1000 rpm. Yes, the ardiuno mega should be of use thank you.
