Unknown specification NEMA 17 stepper motor
Hi, I found some used stepper motors from streets of our local electronics market, which are in working condition. All I know about those motors are 1. NEMA 17 form factor 2. 2 phase bipolar (4 wire)...

You can almost certainly use them. Don't assume they are 1.5A. Instead, look through this list [www.omc-stepperonline.com] for a motor with about the same resistance and length as the ones you found....

Hi, Thanks a lot for your suggestion. Matching with my spec I found Nema 17 2.1 Ohm bipolar. It says the input voltage should be 2.8 volt. I read that for DRV8825 the Vmot( min ) is >4v. So how...

Plug-in drivers generally have a pot to adjust the motor current. 3D printer control boards with built-in stepper drivers generally provide for setting the motor currents using a gcode command, which...

It appears you need to adjust the Stepper motor Current Watch this Video [www.youtube.com] If you still have problems Post again we " the Forum " will help.

You could flash the RAMPS_test program instead of Marlin to make sure hardware and wiring is working. Then take the next step and test with Marlin. Use low acceleration and max. speed parameters first...

Hi, I'm building my first 3D printer, and I'm struggling with a challenge. I'm testing my stepper motors and, although I can make them move correctly, I can not make them move very quickly without...
View ArticleRe: Speed of my stepper motors
What acceleration are you using? Reducing it may help. The torque from a stepper motor starts to fall off above a certain speed, and that speed depends on the supply voltage to the drivers. To...
View ArticleRe: Speed of my stepper motors
That is a wonderful document. Thanks. :) My max acceleration is set to 300 mm/s/s (no thought is behind this number). If I set a desired speed of 100mm/s (6000mm/min) I get a peak back emf of 5.8V and...

Yes the speeds you are looking to achieve are quite modest, so I would expect 12V so be sufficient, assuming they are 1.8deg motors. Are you certain that the drivers are running at 1/16 microstepping...

Oh no. This is really embarrassing! Yes I had set it to half-steps instead of 1/16. I discovered it because my big boy was disappointed that it was not moving yet. When I put all the belts on, I could...

Using them now on my ramps with 1/16 steps in my corexy. They work very good. Little vibrations and very little noise. Thumbs up. Tried them also with 1/32 steps, then no noise at all.
