    First layer quality problem


    I'm having a problem with getting a clean first layer on my Prusa i3 clone.

    The first layer is not going doing cleanly". It has bumps and ripples. I printed one layer, stopped it, and took pictures of the top and bottom of the first layer (below). Otherwise, prints are good - if I let the prints complete, I get good adhesion (sometimes too good and hard to peel off).

    Iím running PLA from various sources (Playphab, Hatchbox, etc.), 0.3mm nozzle. I've tried different bed temperatures between 45C and 60C with no difference. I'm running the printhead at 188C (which gives me great results otherwise as far as bridging, stringing, layer to layer adhesion, etc.). But I've also tried higher temps with no difference. This sample was printed on Buildtak, but I have the same issue on glass with elmerís glue.

    Any ideas what causes this and how to correct it?

    I have good prints and I have bad prints with my Build surface. It seems that they have to be adjusted to it their own G-Spot that your printer likes.

    It also helps to clean the Bed with 70% alcohol just before you print. I like the build surface it Looks better than the old Aluminum bed surface.
    However I still place Tape over the Build Surface as it is less forgiving than the build surface.

    Video was made before I purchased the Build Surface, returned because it still works better on my 3D Printer.
