    I’ve been having real good fun since getting back to my 3D printing, because I wasn’t involved with any 3D stuff for more than eight week, I’ve lost my edge and am making all sorts of newbie mistakes. (Lots of them)

    I am having to learn everything all over again, well the most important things, when I first started back I couldn’t get anything to print, I just keep on getting balls of candy floss on all my prints, despite trying everything possible.

    Then @Redbrickman came to my rescue once again, and all dough I taught his suggestion was a bit stupid, I went along with it, (Naive comes to mind) because I’d tried everything else, with both Gcode and hardware updates and downgrades too.

    He advises me to open a new roll of filament and try and see if that would print with a profile he provided, and to my amazement it worked, all the Friggin PLA rolls I had in the open must have been contaminated with moisture.

    It made a lot of sense when you think about it, we’ve had non-stop rain for the past ten weeks and this filament had been exposed to all that humidity without been used for that length of time, I wrongly taught that PLA was immune from humidity.

    I printed this lovely little USB box yesterday and there wasn’t the slightest problem from start to finish, but then today I tried to print the same box again but this time with an old black roll of filament I’d had drying out in a box for two days.

    The results are plain to see, Moisture does cause problems with PLA filament too...

    Yeah, PLA is pretty susceptible to moisture! I've had the filament get pretty brittle and snap during printing.

    What you're seeing in that black pic is pretty similar to the problem I was having last month. It's often frustrating that problems can come from 100 different sources (nozzle, slicer settings, filament, moisture, etc. etc. etc.)

    When I get so depressed about brexit, and wished I lived somewhere else, I realise there are always some downsides.

    It's going to be ok. There will be growing pains and separation anxiety, but the people are historically proven tough with a "can do" spirit. :hugs

    Suppose you lived in a state that somehow managed to secede from the US against your wish. That's how I feel about having my EU citizenship removed.

    FryingSaucer replied to my Conversation and provided clarity to his position. I appreciate his candor. I will start a new thread in Everything Else for all to comment. It is an important topic for the world.
