For you, what's the problem of my printer?

[Pietrogramma]

Hi everyone, I am attaching some photos of two prints that I made this morning with my Geeetech PROB.
How to see the result is far from satisfactory ... if I print small pieces the print is all messed up, while if I print slightly larger pieces the result is ok.
If you see the picture piece 1 it should look like the one in picture 2 but it's all messed up. In the other two photos, however, if the siphon came out well, the two supports that subverted being lawyers for the stirrup came to all wrinkles.
What is the problem according to you?
I printed PLA at 200 degrees and without supports.
Hello and always thanks

Hi, You can increase support;
Print speed is reduced as much as possible,
and the print range that can be referenced is 30-60mm/s.
I hope this can help you.

Hi William, thanks for your reply.
Thanks to your advice I have decreased the printing speed from 60 to 40 and the printing has improved, even if not yet perfect. I added a cooling system for the PLA and now it's much better.
Thanks and best regards

enjoy!
