### Basic Information: Printer Model: Anycubic kobra 2 neo MCU / Printerboard: Not sure, but microcontroller lablings are GD32F303 RGT6 `klippy.log` [klippy.log](https://klipper.discourse.group/uploads/short-url/tVnrvt091CxSqKIFxMTDF63Po9i.log) (169.9 KB) I use lts raspbian minimal installation on my board. Tried to search for this problem for 2 days straight. Everything works, except MCU. I get the same error everytime. ![image](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/0/0913d7c0cca5335ee17e5be8856756f7fa07160b.png) Yesterday i was working on this problem till 3am and found almost nothing. I hope that smart people can help me with this issue. šŸ˜… Edited: You can find working configs and make requests and suggestions in the link below.

No, the error is not the same. First log: ```auto mcu 'mcu': Unable to open serial port: [Errno 13] could not open port /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0: [Errno 13] Permission denied: '/dev/serial/by-id/usb-1a86_USB_Serial-if00-port0' ``` Second log: ```auto mcu 'mcu': Timeout on connect MCU error during connect ... serialhdl.error: mcu 'mcu': Unable to connect ``` Which would indicate that the board is not correctly flashed. Check with [How-To Trouble-Shoot](https://klipper.discourse.group/t/how-to-trouble-shoot/6326#linux-dmesg-5) to see if and how the board registers to the Linux OS As for the Kobra 2 Neo, I would not be aware of an existing config file and build instructions, so I do not know on which reference you build it. From your log ```auto ========= Last MCU build config ========= CONFIG_LOW_LEVEL_OPTIONS=y # CONFIG_MACH_AVR is not set # CONFIG_MACH_ATSAM is not set # CONFIG_MACH_ATSAMD is not set # CONFIG_MACH_LPC176X is not set # CONFIG_MACH_STM32 is not set # CONFIG_MACH_HC32F460 is not set # CONFIG_MACH_RP2040 is not set # CONFIG_MACH_PRU is not set # CONFIG_MACH_AR100 is not set # CONFIG_MACH_LINUX is not set CONFIG_MACH_SIMU=y CONFIG_BOARD_DIRECTORY="simulator" CONFIG_CLOCK_FREQ=20000000 CONFIG_SERIAL=y CONFIG_SIMULATOR_SELECT=y CONFIG_SERIAL_BAUD=115200 CONFIG_USB_VENDOR_ID=0x1d50 CONFIG_USB_DEVICE_ID=0x614e CONFIG_USB_SERIAL_NUMBER="12345" CONFIG_WANT_GPIO_BITBANGING=y CONFIG_WANT_DISPLAYS=y CONFIG_WANT_SENSORS=y CONFIG_WANT_LIS2DW=y CONFIG_WANT_SOFTWARE_SPI=y CONFIG_CANBUS_FREQUENCY=1000000 CONFIG_INITIAL_PINS="" CONFIG_HAVE_GPIO=y CONFIG_HAVE_GPIO_ADC=y CONFIG_HAVE_GPIO_SPI=y CONFIG_HAVE_GPIO_HARD_PWM=y CONFIG_INLINE_STEPPER_HACK=y ``` These `make menuconfig` parameters definitively are wrong, but since I do not have better ones, I cannot provide further guidance. ---

Ok, i was not sure about klipper, cause flashing my very new 3d printer is pretty scary. But now i think that i could try. I have read discussions about installing klipper on the board with the same microcontroller as mine [(here)](https://klipper.discourse.group/t/installing-klipper-on-ender-3-4-2-2-board-and-gd32f303-chip/8165) but i am not sure how to do it properly. Do you have any instructions for configuring and flashing a firmware to my board? Thank you in advance for any help. ---

Ok. I tried flashing it with SD card by putting firmware.bin file on it but after several tries of powering on and onn my printer doesnā€™t flash.

Unfortunately, I do not know the board or if it has any peculiarities. _Theoretically_ the instructions here [https://github.com/Klipper3d/klipper/blob/9e765daeedb2adf7641b96882326b80aeeb70c93/config/printer-creality-ender3-v2-neo-2022.cfg](https://github.com/Klipper3d/klipper/blob/9e765daeedb2adf7641b96882326b80aeeb70c93/config/printer-creality-ender3-v2-neo-2022.cfg) should allow you to flash the board. Make sure to copy only the `klipper.bin` to the SD card and rename it to something random like blabla.bin Even if you then manage to flash the board, the real challenge will be the `printer.cfg` with the relevant pin mapping. ---

also, look what i found [How to install Klipper on Anycubic Kobra 2 - Function3D](https://function3d.xyz/en/how-to-install-klipper-on-anycubic-kobra-2/) it is for kobra 2 (not neo) but i should try [config.zip](https://klipper.discourse.group/uploads/short-url/ixeOBltGCRk3r52rmit2apVWQWe.zip) (4.0 KB) (downloaded from here) ---

Yes, this is what I found as well. The big issue is that this is based on a HC32F460 MCU and according to your description the board has GD32F303. I do not know if both chips are pin-compatible, but I would doubt it. If you are lucky, and they are pin-compatible, the cfg could be used. ---

iā€™m really frustrated because i just cannot make this work. The board constantly boots to marlin instead. I reformatted the sd card 2 times and it gave me nothing. I gues iā€™ll go and rest a little. ---

Ok. I got in contact the anycubic support. They said that installing klipper on my printer will ruin the official warranty and sent me the only official firmware that they currently have. I think i should share it to you guys and other people looking for anycubic kobra 2 neo firmware. šŸ˜ [Link to google drive that they sent to me (click)](https://drive.google.com/drive/folders/1TNi5x2rCg4tpmZITlUiWC4calGwWwqNz) [ak2neo-1.5.6.3.zip](https://klipper.discourse.group/uploads/short-url/3uaGlZo8ZcqN7RFOXeeUGE7Jty9.zip) (154.8 KB) ---

??? Did they say why it would void the official warranty? I would think that the only (valid) reasons for making a statement like this is because there is danger of damaging the product or could cause personal harm to the user. I would suspect that they are making this statement because they donā€™t want to support Klipper but what level of support do they give if you want to do something like add a filament runout sensor, which would require a firmware change or wanted to change the print surface. ---

idk, i suggest that kobra 2 neo is unpopular model and this raises a problem with making configs and testing them. I really want to get klipper working on my board but iā€™ve never used it before.
