CoreXY Enclosure, frame, and tips Questions.

Basically, any belt section that changes length during xy movement needs to be parallel to the movement direction

Hello,

My name is Sergio and I really need some help, like a lot of help.
I am currently building a Hypercube by Tech2c and I'm having a motion issue
when I hit the home button in pronterface none of my motors move, but that's not it
instead of moving the make this weird high pitched sound and my z-axis motor starts to move then stops.
I thought it was binding so, I took out the lead screw and it
still, does the same thing, also my x and y-axis don't move and make a high pitched
sound, I have a feeling that I'm not doing something right whether it be a Marlin Setting or
something else.

Someone Please Help I really need it

Have you programmed the steps/mm for each axis yet? If not the controller may be trying to drive the motors much too fast.

Some steppers don't follow the cable color standard. Then one coil tries to step clockwise and the other counterclockwise.
You can switch either of the coils to make a test. ( black/green OR red/blue )
