Re: Can't stop Y-Axis motor
Yeah, it sounds like the Arduino board is enabling the Y axis motor for some reason - maybe check the firmware or upload a fresh copy. I assume you have been using repetier all the time? If you...

One of the wires to the connector for my Minebea Nema 17 motor came off due to a back and forth motion from x-axis motor. Where can I find replacement connectors?

I assume you're simply looking for standard 0.1inch pitch female header connectors. Any electronics seller would have them, but if you don't want to wade through the immense on-line catalogs to find...

There are different types of those connectors so i dont think there is actually any standard for that, probably each manufacturer is using its own choice. But for what you have in picture, i think try...

View ArticleRe: Trying to find a stepper motor under 1A but with enough torque
Your drivers are rated for 1A but without heatsink and fan. My stepper motors are 1.7A and my drivers are also rated to1A but with a heatsink and fan I don't have problems.

About the current on the label of the motor, i would rather think of it like a maximum, instead of a target to be hit. About the current level on the driver chip, we actually change that with a...

Hello, I'm new in the world of 3d printers, this week I try to make a Prusa iteration 3. When I was trying to make the motors move, I saw there is something wrong, the motors (NEMA 17 17HS3401) not...

When the pot on the stepper driver is adjusted, it changes the voltage Vref. The current is calculated for each Vref, by a formula that is on the driver ic datasheet or in this case also on pololu...
View ArticleRe: is posible stepper motor in continuos rotation?
All stepper motors have continuous rotation, meaning they can freely spin 360 degrees and is positionable in any fraction up to the resolution of the step (e.g. .9 [400 steps/rev], 1.8 degrees [200...

wow, I don't think you are suppose to turn the trimpots by that much. they are not suppose to turn more than 360 degrees, you may have already killed it. in any case, try turning down speed. it might...

I had the same problem. I thought I knew how the coils were supposed to be connected to the drivers but apparently I didn't. Be sure that you have two wires that read a resistance together on the pins...
