I have heard about that issue already. So far I have one roll just sitting out on the printer and have seen no issues. I will bear it in mind though. I need to look into what other precautions I need to consider and what the regular maintenance should be. It keeps popping up a message about lubricating parts, but I am not sure it should need it so soon. I have seen some tools to print for spreading the grease. It is a precision tool and will need looking after.
Cheers and !BEER
If it complains a lot then give in and lube it up :)
After that, unless it is very dusty, dry, or full of cat hair, shouldn't be needed for a long while.
PLA is not bad for picking up moisture but a bunch of other common filaments are. I use a lot of silica gel packets (not loose, it gets everywhere!) in my filament storage containers, and I have a couple of driers too, but if you are printing a fair but then the main thing is to not leave spare filament lying around.
I just have PLA for now, but will take notice of this.
Nice! My printer reminds me about lubrication only very rarely, and through very audible screeeee :)
