Is this latest print with the teflon coupler in the condition in your photos from the head disassembly or did you clean up the deformed lip?
Well, i didn't really see any way to clean up the deformed lip. I put a drill through the teflon piece, but the 'rut' in the teflon is a temporary *widening* of the shaft - so it could be a 'catch' point for unevenness in the filament - where the filament might have been carried along in the tube, with the kink riding along the inside of the bowden tube - then it gets to the rut in the teflon and it pops into the rut and stays there.
So this print is after I reassembled the head, with some very minor clean up of the teflon.
I think there is more going on.
I would really like to replace the teflon. No answer as yet from the 2 emails sent to Marrit at UM requesting a replacement (under warranty or chargeable)
Do I have the worst results of anyone on this thread ? Anyone failing earlier than 3mm cubed per sec ?
Mark.
