Print fail, how can I diagnose g-code?

jdunnett

I have a print repeatedly fail at the same location. With the error;

Error:Line Number is not Last Line Number+1, Last Line: 391214

Any idea how to diagnose this? Is there a way I can just manually ignore the error and continue to print?

Is there anyway to analyse the G code for errors?

You can enable logging so you can see the full communication especially here how the error happens.
Lines are numbered and one line was missing. Normally we resend missing lines as they are normally caused by communication errors. So what you need to look for is why repeating does not help. Probable a special g-code that makes it happen because line number is ignored for example.
