So I was printing an object for work today, and the printer suddenly stopped and I had a pronterface Error. The error Read:
Error: Line number is not last line number +1
Last line: 6906
Resend: 6910
Error: No line Number with Checsum, Last line: 6909
I am running a Prusa Mendel on a computer with Ubuntu 10. (Not sure of the specifics.) I have had no issues before this and am not sure if it is Slicer or Pronterface or Marlin which has caused this. I would appreciate any help.
Thanks.

Have you got "monitor printer" ticked. I un tick it while building and haven't seen the error since.
