bumps on pla surface

[BiMNrd 10]

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.

Thank you, looks great now.
