Printing stops and continues to print EXTREMELY slow.

I have encountered this problem 2 times in the same day.

I have 2 CR-10 V3 and 2 Artillery Sidewinder X1 + 1 webcam connected to a Raspberry Pi and a USB hub.

Generally shortly after starting one of the CR-10 V3s it begins to print extremely slowly, as if the commands take a loooong time to arrive.

I leave an example with the date stamp so you can see what I'm talking about.

  • Looks like your timeout i set to 4 seconds. So after each timeout server sends 2 lines and waits firmware to send "ok" but this seems to not happen. If you enable ack in log you would see the "ok" at least as long as it works. Communication is synced with these responses so they are essential. If firmware stops sending them you get that pattern.

    Can it be a problem with the usb cable?
    Can it be fixed in any way when that happens?

  • Do you have the firmware sources and are able to compile and upload them? I have a theory what it is, but that needs to recompile firmware with second serial for the display disabled.

    Printer is new and creality don't release source file for this printer yet.
  • Ok see on https://www.creality.com/download the V3 is missing here.
    When you send M115 what firmware does it show? Did they show marlin 2 as firmware?
