    New 3D printer here, so pardon the newbness.

    First layer seems to print fine, but then, disaster:

    1. I notice that the second layer goes alot faster, it doesnt seem to make all the corners as "tight" as the first layer.

    2. When it goes to fill in the second layer *and beyond* its all jagged, its almost as if the head is dragging a bit against the first layer.

    3. It is an R1 purchased recently. If that helps at all.

    Settings are all stock.

    Thoughts? suggestions? Funny jokes?

    Thanks and cheers!

    Probably try increasing the Z offset for the first layer

    If the first layer is too low it can kinda bunch up and get bulges that the print head will print over. You can generally ignore this if it doesn't cause issues.

    Give this a gander: printedsolid.com/firstlayer

    Pictures of your issues are always appreciated!

    Thanks, I will play with the settings a bit tonight and report back later this evening. If the problem persists I will attach pics.

    The faster for subsequent layers is a setting in the slicer.
    Most default go slower on the first layer to insure good adhesion.

    Look in your slicer setting and you should be able to control this somewhat.
    Look for 'fist layer under speed' or something similar.

    You can also experiment with lowering the overall speed. If you consistently have problems you may have something loose in one of the drive trains (X or Y) that is adding some slop.

    Good luck.

    I did two things:

    1. I slowed down the speed.

    2. I lowered the z offset. based on that link provided above, It seems like the first layer height was too high, which cased problems with the layer above mashing into the head.

    This seems to be working now.

    Next problem is the ends are curling up a bit, not sticking to the bed, but I will start a new thread for that and mark this solved.

    thnx!
