Tested the caps, they’re fine. The rubber rollers turn the wheels fine. The IR camera trick doesn’t work here, the IR LEDs are pulsed and it has a power saving function to slow the pulsing way down at rest.
Scoped the Y axis IR detectors and it looks OK (5Khz square wave, amplitude changes with movement). However the X axis did not match. Very much lower in voltage.
