Is the B-stepper supposed to really whine? I just setup my Elite woodworker and the B-stepper really makes an ear piercing whine. The pitch is like a tea kettle at full boil. The noise is quite irritating. Using my phone I estimate the B-steppers noise at 3-4 KHz. All other steppers are twice that frequency. I tried removing the axis cables one by one to confirm which axis is making the noise. Removing the B1 cable always eliminate the noise.
I was thinking about swapping the B1 and Y1 steppers to confirm the noise followed the motor, but since Onefininty labeled each one uniquely I haven’t done that.
I just assembled mine over the weekend and also have a motor(s) giving me a high pitch whine. It started off on a lower pitch and steadily increased. Wouldn’t be so bad if it was while it was moving but its while sitting idle.
