Hello, Have you done what it suggest? ---

```auto ``` Yes, I did. I even checked all the cables to see if they were loose, but everything is secure ---

What have you done exactly? Have you reflashed the firmware? If so, what’s the result of the flash? It maybe also a temperature issue. Is your printer in an enclosure? ---

```auto ``` Yes, it’s in an enclosure, but I removed the lid and the doors because of the heat; this problem arose while printing. ---

Could you evaluate the temperature inside the printer? ---

@Christiaan Welcome. To avoid confusion, please start a new thread under the correct printer model. The error is Klipper complaining it got no response to a MCU id check. Have you managed to connect the printer to your router? Network access will make trouble shooting much easier. ---

I’ve tried that, but it has no effect. ---

The SV08 Max has 3 MCU’s. One on the mainboard, one in the toolhead and one in the buffer (filament pusher). The mainboard includes 2 subsystems: 1. A small embedded computer (SBC or loosely a Raspberry Pi) , RAM memory, and storage for a filesystem. 2. A microcontroller that is connected to various sensors and actuators. Your printer appears to be booting to Linux and loading Klipper normally. The other half of the mainboard is missing in action. That Linux boots eliminates any possibility of a power supply problem. There are no connecting wires (uses traces on the board). The next step would be to reflash the Klipper firmware onto the MCU. There is (AFAIK) no official flash process. @sovol3d You need to reach out to Sovol at [info@sovol3d.com](mailto:info@sovol3d.com) (include your order # and a picture of the serial number sticker) and see if they want to guide you through the flash process or ship you a new mainboard. This user had a similar issue, though he got there using an unofficial flash method). > [@Bricked Mainboard After Flashing Firmware?](https://forum.sovol3d.com/t/bricked-mainboard-after-flashing-firmware/10185/14): > > Thanks to my good friends at Sovol I am back up and running. Since there was no can0 (Errno 19) they sent me the hex files to install with the STLink. The process was not as hard as I thought. Thanks Sovol!
