Hi, very new to this 3D printing scene and have worked my way throught this wiki. I am calibrating the motor but the X platter motor is making this high pitch sound every sec like a heart beating. It also only move x mm a sec when I tell it to move 10mm but not the whole 10mm at a single go and it have a small kick at each move where it move an extra 1-2mm. Y is working as it should but X is acting like it's going to die soon. The "symptom" is similiar to how I would describe a motor would react if it isn't getting enough juice to power it correctly.
