Uneven layering with prints
Hi everyone.
I've had my prusa for about a month now, and up until a few weeks ago it has worked perfectly. Recently, I have been having trouble with calibration and uneven layers. in the top right of the bed, the extrusion lines are too high and don't stick to the bed. In the middle, the lines are perfect. In the bottom left, the nozzle is so close to the bed that nothing comes out. I have already tried moving the PINDA sensor up and down, and I've calibrated many times. This is a very frustrating problem and any help is greatly appreciated.
Re: Uneven layering with prints
From what you tell, it seems that your printer has become skewed.
It may have been caused by lifting and moving the printer (slightly harsh) or by having some screws in the frame loose.
If so, repeat "Y-axis assembly" so that the frame becomes straight again.

You can check the skew under the "Support / XYZ calibration detail" menu, but you must first do a "Calibration / Self Test" first.

Thanks! I'll try this

This ended up working, thanks a bunch! My U-bolts were too tight, which I knew might cause trouble from the beginning.
