First layer lifting
Hello everybody,
What is going on with my first layer? Please see photo. Overall adhesion seems good but some passes on layer 1 seem to absolutely want to jump up. Printing the next layer sometimes smooths it over and the print works well except for cavities underneath. But sometimes these things cause a crash at the second layer.

I'm replying here to my own post. I just discovered that the location of the lifting is non-random; it repeats with subsequent attempts. So I suspect I should clean my metal plate....
RE: First layer lifting
I clean my build plate with Hot Water and a little dish soap, then rinse with hot water and dry with plain paper towel.
After cleaning, keep your fingers off the build plate surface...
with textured build plates, I sometimes need to use scotchbright to really clean the surface

RE: First layer lifting
If the 1st layer is building up something looking like "waves", it can also be that your z-offset is too low. I am not sure if that is what is at play here.

RE: First layer lifting
I would most definitely check the Z calibration, first with the 'zig zag and flag' internal method, and then with one of those 3x3 single-layer calibration prints.
Those 3x3 calibration prints will show up any left/right and front/rear irregularities and allow correction of them.
RE: First layer lifting
This happens to me as well, so I print the first layer at 10 % speed and when the first layer is done i gradually increase the print speed to 100 %. (I know 10% is annoyingly slow, but I could not find another solution) This problem only shows up when I use prusaslicer and I am sure it does not have anything to do with a cleaning the build plate.
