Hi,
I am currently building a Mendel. I ran into a small problem here. I am looking for the stepper motors that should be used. Is there any certain specs.
As far as I know that what really matters is the frame size, either a NEMA 17 or NEMA 14 motor. Also the torque should be 1400 g-cm or more. What about other factors such as the stepping angle size, weight of the motor, the voltage. I have seen a lot of people posting various motors with various specs.
I am looking for a decent motor, which would give me the best printing quality. So what are the important factors I am looking to??
Another thing !! I have known that the lower the step angle, the better. However, I don't think it is irreparable if the step angle is 1.8deg/step or even 3.6deg/step.I believe the stepper motor drivers are capable of micro-stepping. Meaning, it can control the current going to the phases of the stepper, allowing it to accurately do half or even quarter stepping. IS THAT POSSIBLE To BE DONE in A mendel ??
Thanks,
Khaled
