Oh the irony!
Yesterday was my birthday and I got a roll of Matte Ash Gray from my sister.
Today, I saw this thread.
I will load up my A1 and report back on results, but I do suspect the problem (if there is one for me) to be water content. My room where I print ranges from 45% to 65% and I have a terrible habit of leaving reels on the printer. So filaments can suck up water pretty quick.
I ususally run a reel that has been out through 2x 5 hour drying cyles on my Eibos dryer before vaccing and packing.
