Here is my very thouroughly tested config file for the kobra 2 neo with the best input shaper reults averaged from 3 machines; viel spass damit!
#Configuration file for the Anycubic Kobra 2 neo. (Trigorilla 4.0.1 Board)
#please read every comment before changing and using this config to ensure you dont break anything.
#DISCLAIMER
#This Printer config was written and optimized by and with the help of the Klipper forum group.
#THIS IS NO LONGER AS EXPERIMENTAL but still nobody will give you any warranty in case your printer blows up. (which it probably wont)
#version 2.0.1
#tested on 3 printers - fixed errors - generalized file paths - works now.
#please excuse any spelling or grammatical errors in my comments as english is not my native.
#comments by xenyonmedia and mysterious cable (reddit only)
