Yeah I have been considering a new feeder, my only reason for not going down this route at the moment is that the UM2 worked perfectly before so i would like to try and work out why it has since stopped.
I have done a full strip down of the nozzle and run a very extensive clean, so pretty sure that is fine. Just would like to work out why its not performing as before.
Hi Mark,
The first thing you could do is start by replacing the feeder. Many use this one for example and it works really well:

Additionally it will allow you to swap the filament without having to use the change filament procedure and will let you play with the tension a lot better. Check the additional requirements (2 screws and 1 bolt) before installing.
Also if you feel confident you can try cleaning the nozzle even more. Its not because the filament comes out clean that it is clean. You can disassemble the nozzle and use a torch to burn the excess of plastic. Pay attention to the heater and sensor wire because they are fragile.
Good luck
