So today after messing around with the belt and pulleys, it has not reduced the noise at all. I even loosened the belt to around 50hz, tried a tiny bit of gear oil on the pulleys for the heck of it but had no luck. As far as I can tell the system is working fine, the drive system is just.. loud. I’m starting to suspect a pulley bearing perhaps? Anyone else’s kit this noisy? Still waiting to hear back from KW
