All parts are stock IE at the moment. I looked again and it seems the bets are out of alignment at the ends (cable tie) I’ll redo the cable ties and try to achieve better alignment. It could well be excess tension on the belts too. I opted for the white PU belts with the steel reinforcing (zero stretch) and they require a lot more tension than the rubber/glass fiber belts. I’ll play around tonight and post back with any solutions I can come up with.
Thanks for the advise mate.
