from UM. it appears that they suffered two unfortunate events at the same time for machines shipped early this year - the first was their filament suddenly started varying dramatically in diameter across a roll (I measured 2.6 to 3.1mm) and the second was a fault in ID of bowden tubes (which were too small - mine was 2.92mm).
I expect it accounts for many of the problems people have been having but can't have been good for UM reputation.
anyway, if you ask them nicely they are good people and will replace either if defective. the new tube they supplied is much better at 3.20mm ID and I can now use all the thick filament I had put away.
but what's your opinion on the grease vs oil vs other? which do you use and what have you found?
