Yes i'm another newbie and i've come with little knowledge and therefore many questions!
I want to build a cnc wood router. But before I get into the mechanical side of things I want to get my facts straight on stepper motors and drivers.
How does it work? If the motors are rated at 3 Amps per phase (bipolar, series connection, 6 leads), does this mean in bipolar operation i need to have 6A (3A phase x 2) continuosly available for each motor? (18A total)?
So do I need a 6A driver or a 3A driver (each axis)
Also my machine will require my motors to hold their position while under force from a load.
The motor will be connected to a driver that is on, but the stepper is not stepping, it is
just holding the weight of the load (Z axis). Will this use/dissipate more power than when it is stepping
under the same load? How is this usually done?
thanx
