Is a NEMA 17 stepper motor enough for 3D Printer?
What do you guys use for 3D Printer? NEMA 17 stepper motor

i think its not just about the NEMA size. i have been experimenting with cheap allegro drivers. the operating parameters are very very important.

hmmm maybe, you can make a encoder knob thingy, send that pulse into a logic buffer, then drive some kinda 74xxx octet decoder? make that decoder reset at 4bits and pump that into another set of...

Hi, As redreprap saied,the parameters that come with the motors are extremely important. You need to look for both the torque AND the AMP/PHASE (current). If you are using the 4988 stepstick (or...

View ArticleRe: best motor: high torque or high resolution?
The 4800g/cm motor is technically a "better" motor, but you'll need to feed it twice as many steps, so there are two limits, first, max travel speed will probably be reduced from what you can achieve...
