Diagnosing Benchy deficiencies... Overture PETG on MK4

Ambient Temp 36C

Ambient Humidity 55%

all models sliced with .20mm layer height, stock mk4 settings with the exception of filament types.

EDIT: Also to add, Printer is in an Prusa enclosure, doors open during PETG printing. enclosure is on a 2x6 workbench thats bolted to the concrete wall. so work surface doesn't move at all.

 

My first Benchy print , First print ever -  Prusa Prusament PLA Galaxy Black that came with my printer (Right), Sliced in Prusaslicer with Prusa Prusament PLA

Third print benchy in Matte White - Elegoo Matte White PLA, (Left) Sliced in Prusaslicer with Generic PLA

After printing most of the "unofficial prusa drybox, my daughter saw the orange and demanded a benchy for her set...

so 12-15th print;

Benchy is Orange - Overture PETG Orange, Sliced in Prusaslicer with Generic PETG

I get what youtube calls ringing or ghosting around the front portholes, and some weird variations in the left bow area.  is this due to the significant temp differences on PETG?  or after 40-50 hours of hard work on my unofficial prusa drybox project, do the belts need adjustments?

I'm a little confused because the model seems okay, but the PLA models are absolutely perfect, and the PETG model had weird variances.

 

 

Also to note. for whatever reason, one of the drybox prints jumped on the x axis. which i didn't understand, realize or see until the print was completed. so a loose X-axis belt is possible.  but i have had my printer for 8 days now, and she has been a busy girl for pretty much all of it.

just seeking advice, or chasing "ghosts" 🙂
