(Things I have changed) nothing really, I had an issue a few days ago with my power supply to my driver so I had to disconnect my port and bring it into the office to take a look at it. But there was nothing wrong with it, my on/off switch had some dust in it and just needed a quick cleaning. that is the only thing can I really think of.
I understand that the stepper motors make noise but these sounds are at different pitches and frequencies, and it varies on the speed of stepper motor. It is not quiet noise, I can handle and understand a little noise but this is something more out of a sci-fi / 80's synth music going on.
I am sure there is something I can do to make it more manageable, any suggestions?
