Benchy hull tip burred

Hi there,

Another week, another question. The benchy below has awful corners yet the belt tension seems fine...

Any tips on how I could improve this?

That benchy looks like the temperature was too hot, you didn't use PLA with PETG settings did you?

Regards

It's printed on 205°C while the range indicated on the filament is 195-215°C. I've now started one at 195° to check the difference.
Rest of the benchy looks OK except for also the corners on the back of the boat (lower deck).

Must say that 2 years after I have my mini, there are a lot of things that need adjusting, tweaking, etc. Anyone else with this experience?
I also have to put my Live Z-adjust higher because between every reboot, the nozzle is too high above the bed. I presume this is something the MINDA could solve?

I hadn't thought about having had my mini for 2 years, it doesn't seem that long but must be as I was an early adopter.  Tweaks go with the territory, we're dealing with a device that has very close tolerances.   For a common print each layer is 200 microns, that's pretty small, heat and cold expansion and contraction can have an impact.

As for this, I don't know what this means:

If you're having issues with first layer calibration, do a first layer wizard and show us 2 images, one of the whole bed and another of the little rectangle at the end.
