Filament dehudification
I have left a roll of prusament filament on the machine for several months. It is no longer adhering properly to the platen so I conclude that it may have absorbed moisture while exposed to ambient indoor humidity.
Has anyone else had this occur? If so, is there a way to dehumidify filament after it has been exposed in this way?
RE: Filament dehudification
The three common reasons for prints suddenly failing after a printer has been unused for a while:
A dirty print bed. Give it a really thorough clean and avoid touching the print area.
Damp filament. Look up threads here about drying filament especially if it has been left open. In poor humidity filament can be visibly affected in just a few hours. If you don't have access to a dryer or dehydrator you may find your domestic fan oven can be set to about 50 degrees C (intended for baking meringues) and if the door is left slightly open to allow air changes it makes a rather inefficient emergency dryer.
Gneral neglect, dust and cobwebs... Basic cleaning, lubrication and general maintenance have all been missed.

Cheerio,
RE: Filament dehudification
Thanks for your prompt response. I installed a new filament spool and the printer worked beautifully. So it is the filament.
Your recommendation for dehumidifying the filament is very helpful. I’ll give it a try.
Thanks.

Cleaning up print bed as suggested by @diem should be your first go-to.
After that, if you want to look more into Filament dryers you can search the forum and will find suggestions for every need and the some. If you are looking into purchasing one I do like the information provided here: https://www.mytechfun.com/filament-dryers - the YouTube thread on comparisons is highly recommended on many 3d print forums (and I personally found it perfect for my needs).
