Hi!
Just finished building the microscope and it works really great. However, there is one issue with controlling the stepper motors: The X axis motor often won’t stop turning (and continues even after the RaspberryPi is shut down, only unplugging the power helps). This problem occurs randomly when moving the stage via entering x coordinate numbers, but it always happens when I am using the keyboard arrows, only with the left arrow though. Is this a Sangaboard hardware issue or could it be something software related?
