This is the base of a pumpkin. There is a little support where the over hang is a bit much to start. How did I get great smoosh on the support but not the first layer of the actual print?! They’re the same layer!

    I’m not entirely sure what’s going on… I’d have to check the model (and even then… slicers can do things weird).

    That said, my guess is that the model’s base isn’t perfectly flat it looks like it tried to generate some rafting, but was too close or something to generate proper support.

    My advice is to check the gcode in your slicer- that’ll show you if it’s a gcode issue or a printer issue.

    If it’s gcode, try raising it by 1mm off the plate and tell it to generate support every where. If you’re using Prusa slicer, maybe consider the tree supports

      I was going to suggest the opposite - lower the model .5 mm in to the platter to cut a clean bottom and ensure it’s flush.

        that works too, assuming it lowers it enough to get a sizeable patch. either way will get a decent print. They’re already printing with supports, however, so the loss in quality from janky support removal isn’t in play.

        (ah crap. Sorry for the pun.)

    Look at your first layer in the slicer. I suspect the bottom of the pumpkin isn’t flat and that the center of it is raised some, so not much of the actual base is touching the bed. To fix this you can either lower the pumpkin some (basically cropping the bottom flat) or print it on a raft and make sure you have supports everywhere.

        Also check that the bed itself is still flat.

        Remember that despite all the software and electronics printers use, they are ultimately hardware, and hardware wears out and breaks sometimes.

        My glass bed has warped over time with heat cycles to the point where the center of the bed is a full mm lower than the edges and corners. Every slicer setting in the world can’t fix that. The fix was a new bed, or you could work around it if you have a touch sensor to make a bed mesh, but then the bottom of your parts still won’t be flat.
