i need help, my anycubic kobra 2 is printing its first and sometimes second layer perfect, but every layer after that is way under extruding, I have tried many thing including diffrent filiment new firmware, diffrent bed temps and extruder temps, and even replaced the part of the extruder that has the stepper motor and gears, i have tried ajusting the flow rate. Does anyone have any tips?

It sounds like you have tried a lot of troubleshooting steps already. One thing you could check is the tension on the extruder. Make sure it is not too tight or too loose. You could also try cleaning or replacing the nozzle in case there is a blockage causing the under-extrusion. Lastly, calibrating the extruder steps/mm in your firmware settings could also help improve extrusion consistency. If none of these steps work, it might be worth reaching out to AnyCubic's customer support for further assistance.

Not sure about the stock hotend but this might be relevant:

Hottightening the Nozzle

Tighten your nozzle at the highest possible temperature to make sure it fully seals against the heatbreak.
If the nozzle bottoms out against the heatblock, the heatbreak is not installed correctly. Refer to the graphic. Note that the maximum printing temperature is about 20C lower.

If you have a PTFE lined hotend, make sure you have taken care of ?thegap

If you can resume printing after cooldown (for the first layer at least) its not the gap

#

Does your hotend cooling fan work?
