I am consistently getting an error at the end of my prints which kills the print. The log for the error looks like this:

Quote
Resend: 74166
Error:No Checksum with line number, Last Line: 74165
[ERROR] Error:No Checksum with line number, Last Line: 74165

Resend: 74166

and so on, ad infinitum.....


The problem consistently happens with 6 lines of G1 commands left to run, and the printer head hangs up on the (*almost* complete) model at temperature, creating a wart on my print which ruins the print.

Here is an image showing the error, and three examples of g-code showing where the print failed:

This is a new problem, and the only thing that I can figure that I did to change things was to add the "Eject" command at the end of the g-code, but I don't see how that could cause this....

Any speculation on what might be causing this?
