This just happened for a second time… I’m running octoprint on a windows desktop computer that lives next to the printer (no raspberry pi for me yet).

Twice now, it has disconnected mid-print. The printer and PC are both online and physically connected. Disconnecting and reconnecting in octoprint works, and I have been manually checking the last gcode sent successfully in the terminal and copying the remaining code out of the file from there and printing that - it works but if it has been disconnected for a while before I notice, the spot where the extruder was sitting gets a little melty and there are some artifacts in the print.

Is there any octoprint plug in that can automate this process so I don’t have to manually edit the gcode? Or any tips on preventing disconnects?

I’m pretty new to this whole world of 3d printing and even newer to octoprint so I may be missing something obvious.

Thanks!

    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

      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.

    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

      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.
