I've been working on a hypercube 3D printer for a little while now and I have many problems, I have a ramps 1.4 sheild with an arduino. I have 2 z axis motors. and a full graphic smart controller from ZYLtech.
My first problem is that the display doesn't turn on unless I have the USB plugged in, as soon as I unplug it the display turns off. also the display gets significantly dimmer when the 12v power is turned on.
My second problem is that the motors do not spin at all, I have tried the ldc control, Pronterface , and uploading G code. When I tell them to move the display says that they changed position, but they never moved.
My third problem is that the endstops only recieve power when the USB is plugged in, just like the display.
Hopefully I gave enough information for some advice!
