swap the `G1 X60 E25 F500` to the `G1 X120 E25 F500`, your line will be narrower ---

Same problem just different values ```auto Move exceeds maximum extrusion (1.074mm^2 vs 0.640mm^2) See the 'max_extrude_cross_section' config option for details ``` ---

is #position\_endstop: 0 correct? I think the z-offset is not saved or as soon as I restart the firmware the z-offset is zero again, even though I saved before. The first layer is also bad again ````auto [stepper_z] step_pin: PB0 dir_pin: !PB1 enable_pin: !PA15 rotation_distance: 8 microsteps: 16 endstop_pin: probe:z_virtual_endstop endstop_pin: ^PA0 #position_endstop: 0 position_min: -1 position_max: 250 homing_speed: 4 second_homing_speed: 1 homing_retract_dist: 2``` ```` ---

Hi All, I successfully installed the firmware by @kvgx12 and was able to setup my Kobra 2 Neo. Mesh Bed Leveling and Calibrate\_Z also working. Moving X, Y and Z by the user interface also working as expected. But when I print something, it seems that the z-offset doesn’t work proper. The nozzle scratches at the bed and seems not move up at the next layer. I played a little bit around with the z-offset but it always seems no effect. z doesn’t move up and the nozzle scratches at the bed. Any suggestions how to fix this? I’m not able to make a more or less proper print. Many thanks, Christian. ---

I’ve already tried swapping the SD cards, i’ve already tries swapping out motherboard, i tried both at the same time, i just cannot get the klipper to work guys. I am really frustrated because i wanted to run it for the last 2 months and everyone except me here runs klipper somewhat successful. Thank you for all your help, but i need to take a break. I think i’ll stll be reading the thread from time to time but i’ve burned out a lot from this. See you some time soon. ---

Give it a try again the last time but using windows. My daily setup runs Linux desktop, but only using Windows to format SD card to FAT32 and uploading firmware.bin work. So give it a try, good luck! Take a firmware.bin and config from this thread on Reddit: [https://www.reddit.com/r/klippers/comments/18ub6mt/comment/kgcpcps/?utm\_source=share&utm\_medium=web2x&context=3](https://www.reddit.com/r/klippers/comments/18ub6mt/comment/kgcpcps/?utm_source=share&utm_medium=web2x&context=3) Good luck and have fun! (but be aware that i am not sure that every thing will work as expected) ---

I think LCD display from K2N needs **brand new** driver for klipper based on stock Marlin firmware from Anycubic.

Guess what? It flashed first try! I have decided to go to my friend’s house and use his pc to flash the firmware, now it works I think it’s because over the last year i’ve done way too much modifications to my linux installation and because of that there is 100% probability that i broke something lol. I really need to consider distrohopping. ---

Does your kobra 2 neo first layer work fine with marlin? I’m running into a weird issue where mine gradually loses its position, (the bed getting lower in relation to the nozzle)I print the exact same file repeatedly, and never touch the z-offset myself, or leveling. The first few prints the nozzle is too close to the bed, then it starts being perfect, and then the last prints the nozzle is too far away from the bed. Starting to think its either the stepper motor or the motherboard 😕 ---
