*Solved* MMU becoming more unreliable the higher the print
So I have been really struggling trying to get our MMU to print anything other than a short test print. I would get an ever increasing number of filament change requests the longer the print would be (and thus the higher the print would be). The problem turned out to be the filament selector on the MMU flexes from the Teflon tube pulling on it and throws the sensor off. I raised up the carriage all the way in Z to put max tension on the tube and reset it. That and changing out the tube and fittings for a 3mm id tube eliminated my constant filament change requests and grinding problems.
