Printer stops several times during print. "Communication timeout - reset send buffer block"

So my printer is stopping every minute or so, resuming after a minute or so (image attached).

Here's an example of a log fragment from one of the times it stopped:

I really don't know what to make of it, everything looks fine to me.

The printer was printing PLA just fine, it started doing that when I switched to ABS. I never print ABS, but for this project I'm working on, it has to be ABS. Is it possible that the printer is not handling the higher temperature well?

I'd really appreciate any help you guys could give me.


  • Looks like you have ping pong enabled. Disable it and you have good chances that it does not happen any more since we can then fix it in the fly. Since it happens only with abs it might be that the higher energy required for extruder increases communication errors, which disabling ping pong has a good chance to fix.
  • Forgot to update. The problem seemed to be the version of Windows in use. All the computers I tried with Windows 7 had this problem. Once I switched to computers with Windows 8 or 10, the problem was solved.
