I’d say less than 5% chance it helps. But I REALLY don’t know exactly where the pipe is broken so I could be wrong. ---

OK….I’m in contact with support, but so far I’m only at the “Is your printer turned on” stage, so this could take a while. I VERY MUCH appreciate your help and time and effort, so Thank You! ---

So…I reflashed the EMMC, and it DID get rid of the “resize file system” error, but still showing this mainsail error: ![afterflash](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/f/fbbc8d218b5426d0e0b10d16cea8dd57e4c81ccc.png) I re-ran the 3 ssh commands in putty (highlighted in yellow) ![newputty](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/4/44d7c450f4749916fa1150075f2a5c945fac7b8d.png) My untrained eye went to the last line: No mcu\_klipper.bin found… No idea if that’s relevant. ---

Well it is still able to “talk” to the buffer\_mcu. I’d run the last command again now that the updates are in place. If that fails you’ll need to navigate to `/home/sovol/build` and look around. I use WinSCP which is super simple. You can SCP from the Mac terminal but I don’t know of a GUI for Mac. ---

Neither do I, Also not on Sovol’s github @sovol3d You advertise as an “Open Source” company. Where are the firmware .bin files? Has anyone dug in and found the URL for the OTA updates? The ones for the Zero were hosted at Comgrow. ---

Okay I drilled into the image file and extracted the 3 build configuration files. I was able to get a good enough photo of the mainboard to be positive which MCU chip it had. Only one of the config files was for that chip. I then loaded that file into my klipper host and used kiauh + the build system built into klipper to roll a new .bin file You’ll need to make a /build folder at the correct path and copy this in. Roll the dice and hope. [mcu\_klipper.bin](https://forum.sovol3d.com/uploads/short-url/96p0sKs6etFmTjZQXvoicdvydXP.bin) (42.0 KB) ---

Try To stop the Klipper service, use the command `sudo systemctl stop klipper`. This will halt the Klipper service on your system. then `./printer_data/build/mcu_update_fw.sh` ---

@DevildogMP Has Sovol provided any solution path? I’m out of ideas. The update script expects to find a serial port. @AlwinA ‘s functional machine doesn’t show a typical USB\<\>serial converter either. As far as I can see your device lists are identical. It is possible that a programmer such as an ST-Link is needed in conjunction with the script. If Sovol support isn’t providing satisfactory progress I recommend you create a synopsis of this thread and post it to [https://klipper.discourse.group/c/general-discussion/6](https://klipper.discourse.group/c/general-discussion/6). You’ll get complaints that Sovol runs “dirty” Klipper and “support will be limited”. Hopefully one or 2 of the VASTLY more knowledgeable folks will take on the issue (very likely). Be sure to include your klippy.log. Keep us posted on Sovol’s solution path. ---

Thank you for all the time you spent trying. So far Sovol is communicating about once every 2 days with what seems to be scripted responses….had this thing coming up on a week now and can’t even get it running. I realize they’re a big company, but they took my money and sent me a non-working unit and don’t seem to make it a priority to fix the machine. Again, thanks for your efforts. I’ll let you know what eventually comes of this.
