Got lazy but have posted once about my Extruder being the reason why Octoprint or Firmware is not starting the Print.
I compiled my Marlin Firmware by adding
#define DEFAULT_Kp 16.44
#define DEFAULT_Ki 1.58
#define DEFAULT_Kd 42.75
and it starts, but it does weirdly extrude. When I hit "Extrude 5mm" Manually while nothing is running then it seems like a nice constant flow, but when Printing it somehow stocks, retracts or smth when trying to print. At first I thought its TPU and a new abstract material I have never touched but this currently is the good old Black PLA from Creality that I always used.
I use Cura and just used the default settings for PLA like always.
E420.69 is just a placeholder. For my Ender 3 pro it is around 99. Default is 93.
I still feel like something is wrong because the print looks rough. I measured the length and calibrated it to E427.09 and now it looks like the gaps are filled better but still, the side wall is not sticking to the print at one side. I wanted to print a long sheet as bookmark for context. I guess I create a new post later.
