I have a USB 3.0 micro cable in an assembly (below) where it attaches to a PCB on a sliding tray. Unfortunately, in the physical prototype, the cable is too stiff and causes the tray's stepper motor to struggle and stall.
Ultimately I will switch to an FPC-cable solution to address this properly. However, I was wondering if in the short term I could simply strip the PVC housing and shielding, and cut all USB 3.0-specific cables, leaving just the thin D+, D-, and 5V / GND wires. (The connection is to a raspberry pi which doesn't have USB 3.0 anyway).
Is it ok to cut the USB 3.0-specific wires and leave them floating? They have their own housing and are still pretty stiff even after the PVC is removed. I'd like to minimize the strain on the stepper as much as possible.
