My printer can successfully print many other objects using the same settings and same filament.  It just has a problem with this object.  I used the PrusaSlicer to generate the gcode.  I'm using standard 1.75mm Prusa PLA filament.

RE: Nozzle scrapes initial layers

Looking at the outer edges of the print and the cupping at the ends, it looks like improper bed adhesion or 1st layer calibration.  I'm assuming from the temperatures is probably PLA.  I would try or at least check the calibration and reclean the build plate.  For PLA and a smooth build plate, I always use Acetone.  When I use Isopropel Alcohol I always have bed adhesion problems.  Even with 99% pure IPA. 

If I've printed PETG and or used windex or similar to reduce bed adhesion on that surface, I have to clean it really well with liberal amounts of Acetone to get the bed adhesion back. I use one side of the sheet for only PLA and the other side for others.  Cleaning the PLA side with Acetone and the PETG, ABS etc with IPA, then recoat with windex or similar.

Keep in mind that using Acetone is only for the smooth sheets.  The satin and textured can be damaged by Acetone.

Save your print & settings as a 3MF project file, zip it up, and attach it to a reply here. That way we can see your settings and configuration. Otherwise, we're just poking at things.
