In my experience different types of nylon vary a lot in the amount of moisture they absorb. The ultimaker brand nylon prints pretty easy imho. I never dried it but I keep it in a box with descendants. Even during printing. I've also used samples of other brands and found some to be very difficult. It also matters where in the world you live... I'm not in a very humid place so that also helps ofc..
When you material gets to wet you can usually hear it when printing.
I have never printed with nylon, so I am guessing here. Nylon is *very* susceptible to moisture absorption. In injection moulding it is known that in only a few hours, it can absorb so much moisture from the air that production is impossible. So the material has to be dried well, and kept dry during the whole process.
Could this also be the problem in your setup?
For printing nylon, you would first need to dry the spool in a temperature controlled oven. And then store it in a fully closed box with rotating spool holder, also *while printing*. With only a little opening for the filament to exit. Also, put a big bag of desiccant in that box.
There have been talks about several proposed models in this forum, some time ago. Maybe you could find them back? Big food boxes could be a good starting point. Or dedicated machines (I don't remember their names).
But as said, this is guessing.
