Strange under-extrusion
Hi all,
Just bought and assembled my first MK3s+ just week ago. Can you take a look at this print?
There is a problem with it, and I cannot find similar pictures on the web. The problem happens usually on one side of the print.
I checked belts tension, X is 247, Y is 258. The material is FormFutura PLA, sliced with Prusa Slicer, layer height 0.15 mm.
I will appreciate any advice...

The picture does not give us much to go on...can you post the zipped .3mf file for the project please?
Cheers,
Tim
RE: Strange under-extrusion
*.3mf are project files, right? I don't create them yet. I own three Ultimakers 2, but they are few years old now, so I want to give a chance to the Prusa MKS3+.
So, I just import STL in prusa slicer, and go with gcode. Anyway, the situation got better when I lower the hot end temperature from 215 to 200 degrees.
I guess that is the lower limit for PLA, right? At least, that's what FormFutura PLA producer claims.
It looks like your filament is damp, drying it should improve matters.
The belt tension figure is a measure of the resistance felt by the stepper when moving the axis. On a correctly set up machine this does equate, roughly, to belt tension.
But other things can affect mechanical resistance.
Make your next print this:

It MUST be printed in Prusament PETG or the spring tension will be wrong.
Let us know how you get on.
Cheerio,
