first layer print quality
My printer was great for 2 years, and started to have issues with print. I cleaned and replaced hot element (during cleaning the old one was damaged), changed tip to ruby, and calibrated first layer a lot to finally able to print the 9x9 prusa first layer (see attached). The good setting for the build in calibration (900) is not good for the 9x9 prusa first layer, I have to change to -1100 to make the 9x9 prusa first layer work, or else it has defects (if I use -1100 the build in calibration appears to be a bit low since the lines seems squeezed).
Attached is the 9x9 picture, the shapes are fine but the quality is not good. Any ideas? Tanks!
Your first layer calibration is a fraction too low, too much squish.
Cheerio,

Thank you! But if I don't do that the print is not good either. See below:
-1000
-1050 to -850
-1050
-850
-900

I think I need to do Bed Level Correction
