I am watching m printer set the first layer and I am noticing the artifacts below.

this is UM PLA. Any ideas what could be causing this? I am using the OTTB settings for UM PLA.

    This is more or less normal and is no longer visible after the 2nd layer. The reason can be an uneven bed, a slightly thicker layer of glue stick is enough and the distance between nozzle and glass is a bit too low.


    You could also try to go a little lower with the temperature, this can also help.
