I had the same issue and I think it happened because of a cheap USB cable. It sometimes even disconnected when I touched the cable. So I switched back to printing from sd card.

Yeah I will try switching cables and if it happens again I'm going back to SD cards. I really liked the convenience of it but that is not applicable if it keeps failing
You need high quality USB cable, not too long and try not to guide it next to stepper motor or stepper motor cable. Just rerouting the cable might fix the problem
I didn't think about interference. It is pretty close to the bed heating cable and the extruder cable. Probably touching those at points. I will probably stick with the SD card until I can get a Pi and use a much shorter cable. I just lost a print due to this happening 3 times and at this point I don't want to risk it again right away
I had a similar issue on a Pi and switched USB cables, which resolved my issues.
Ahh that makes sense. Both times have been since I switched to a new cable. Guess I got a bad one. I'll switch back to the one I had before.
Why are you using Octoprint instead of Klipper?
Octoprint is a software to manage a printer running marlin firmware.
Klipper is a different printer firmware, and is not something you can use to manage a printer running marlin.
I do want to look at flashing klipper to my sv06 someday but right now I'm just trying to print stuff without manually moving an SD card every time.
I used Octoprint for a few years before switching to Klipper. Octoprint was good but Klipper was like discovering that you can fly.
Are you using mainsail to interface with the printer? That is what I have seen most people recommend for klipper printers
Mainsail on my computer. KlipperScreen on my printers touchscreen. MobileRaker on iOS. I also use TelegramMoonraker to interact when away without opening ports. All managed via Moonraler (klipper’s API)
