    Ah right - makerselect.
    Okay so proper prusa design i3.
    Nice machines.

    It's a Direct drive gambo.
    So not a tube issue.

    Have you checked the grubscrews on the extruder drive gear ?

    I...

    As far as I can tell from the extremely confusing 'which way up' explanation - your bed is possibly not level.

    Lights, huh - clearly essential to a succesful print.....

    solid pla is probably stronger than most epoxy.

    okay - first, why did you change an extrusion setup that was working ?
    Rule 1 in 3d printing - as in life - if it works: LEAVE IT ALONE.

    the best print surface I've used is printbite, but cheap self adhesive PEI is a good alternative.

    I also add the odd bit of print glue, for stubborn filaments: different filaments have very...

    well a couple of things.
    Copper is maleable, that's quite different to it being soft.

    electroplated coipper is actually extremely hard.

    It's also a real PITA and a very hit and miss...

    2 things.
    1) Don't change printing temps mid flow. The hotter the pla the more it will shrink when it cools down. print the whole thing at 210 or 205 or 200. Changing temps is a youtube numpty...

    yes such filaments do exist.
    No you can't print them on a prusa :-)

    PEEK is the best hi-temp filament around.
    be aware it can cost in excess of 500 euros per kg.
    Needs a hi-temp heated build...

    depends on the slicer. but generally that should not change - unless you've changed the infill which would effect the size of the gaps that need to be bridged.

    okay - first thing.
    You NEED to know what the slicer settings actually are.

    yeah the top number of layers is low, and the top skin is too thin.

    So the plastic is falling into the infill.

    More top layers should fix it.
