  • Hi every one :)

    Can I use this on (https://www.adafruit.com/products/352)? I was wondering if I could mount on the 240VAC side.

    TNX.

  • The same observation. I have some 3D-printed part around it, and they start to smell like heated plastic after a while…!

  • Hi

    I have bought 2 motors. One of the motors is working fine in both directions, yet the other one rotates sluggishly in the reverse direction. When I, for example, set the speed to 1000 and the number of steps to 5000, in the positive direction, it rotates 5 seconds and displaces the attached belt 7 cm, but when I reverse the direction, it still rotates for 5 seconds, but at a low rate, and thus moves the belt only about 4 cm. I detached the belt as well and observed the motor separately, but same sluggishness persists. Any ideas? Has someone faced a similar issue?

  • Hi

    I bought two sets of Big Easy Driver and Stepper Motor With Cable (https://www.sparkfun.com/products/9238) form your website. According to existing sketches, I built up the circuit for one motor-driver set and it worked absolutely fine, but for the other motor-driver I couldn’t get it to work with the same configuration!! The second motor only draws 0.01 A current. To solve this problem I did several things: 1. I checked whether the motor is working find by attaching it to the other driver. Two motors are OK. 2. I requested for an RMA and got a new Big Easy Driver Board. At first it worked but then stopped working again. 2. I desoldered and re-soldered the second circuit multiple times just to make sure that bad joints weren’t causing the problem. One time I go it to work (12V, 0.65 A), but the next day when I turned the power on, the current went back to 0.01 A. 3. I changed all the wires in m circuit to make sure short circuit wasn’t the reason.

    Still I can’t figure out the issue. The other set, works fine with identical circuit and power supply, but this one…!!! Any ideas, pls?

    Thanks.
