Was this using the poly box humidity test? What kind of filament? Any more details?
I just printed this yesterday for a project. Bambu Basic PLA dried to where it shows 10% indicated in the poly box humidity test. For scale, the very narrow rectangular hole in the diagonal bar is 50mm long and 0.4mm wide. It’s just a little over a couple of inches across. The white pockets are printed separately and slide in.
I have a hydrometer in my ams to keep track of the moisture. When it gets to 20% I will dry all the rolls I currently have in the ams. Usally takes a good while to get to 20% with the desiccant I have in it.
That’s a good indication your filament is in pretty good shape. Since the AMS has desiccant in it that hides the filament moisture to an extent, though. If you have a poly box and hygrometer, it would be interesting to see what the poly box humidity test says about your filament water content.
