Hi thanks for reply
I changed the PTFE coupler last weekend and have done 5 prints since but 50 hrs is hardly anything. I often do prints that long.
Im running innofil abs at 225 and trying to use some colourfab pla at 200.
do you have any idea what happens to the page to cause issues? is it gripping on the filament or something? I will investigate some TFM parts

Print hours since the last time you changed the PTFE coupler? (It has a print life span of 50-200h depends on the temp) So it might be just that.
Also photos, always photos. Show photos of your hotend setup, I seen many users that don't install it right and while it can work, it gives a lot of trouble.
So.. I think you just need a new PTFE coupler. Also, some 3dsolex distributors sell a TFM coupler, that is a material that can resist the heat much longer and is the same material used on um2+ hotends, and on um2 can print for 500-2000h... I never seen anyone using it on umo+ (at least not on the forum) but should work much better than the standard.
