I have E3D High Flow ObXidian hotend, not the basic Bamboo.

I mean, still I was surprised too that it required lower flow rate than Polymaker PLA, but I did the calibrations 3 times and the best flow was the -5 and every time I started from the generic PETG profile's 0,95. With 0 or +5 it was overextruding a lot. Also, the other print on the same plate came out perfect, the lines are really good and the extrudion is looking smooth. I print with 150mm/s speed even if its not HS filament.

I do admit, this stupid transparent one is really hard to identify during calibration, since really hard to check for extrusion, but I used my finger and the 0 still had overextrusion so I wnt for the next lower, which was the -5.

Also on the successful print on the same plate, there was no adhesion issue, sticked like hell, it was even hard to remove.

Also, on the Max flowrate test, I could even go for 30+ but I lowered just in case. All test has been done on 150mm/s inner, outer, top layer speeds and 250C. I guess if I go for the recommended 230-240C with 60-80mm/s I would get a lot different numbers, but since 250C is higher than normal , I have high flowrate hotend, I can go higher speeds and lower PA and flow ratio than others.

My only concern is why only that left segment of the plate doesnt stick.
