Hi,
I'm looking for some pointers on what I might be doing wrong in my hobby project. I've recently purchased a DC and Stepper Motor HAT for Raspberry Pi and following this guide: https://learn.adafruit.com/adafruit-dc- ... i/overview
I've soldered and powered everything up using a 12V 2A power supply and all the test code runs successfully.
I am now trying to drive a bipolar stepper motor like this one: https://ooznest.co.uk/product/nema14-stepper-motors/ I have the smallest one and the technical sheet says its a 1Amps/Phase at 12-24V.
From my limited understanding that should work with the hats 1.2A per channel 12V output and my power source should be enough to drive one of these motors. However the moment I plug the motor in the power led on the hat starts blinking once a second and while the motor does spin when I run commands it runs intermittently. Eg: I run it 1000 steps on a loop and it spins 4-5 times
with breaks in between.
Am I just not running enough power for this motor or is it something else. Should I try a 12V 5A power supply or would that damage the HAT?
Thank you very much for your help!
