Too many lines to buffer, cut off

What is the problem?

on small printer jobs it sometimes says "too many lines to buffer, cut off" and it stops and makes some bubbles but not always and it prints a bit and then it happens again on the same printer job

What did you already try to solve it?

I do not know what to try

Have you tried running in safe mode?


Did running in safe mode solve the problem?

I don't know

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible


The two are not directly related, but may indicate part of the problem.

The 'too many lines to buffer' means that the lines are going too fast to the printer that they cannot be shown in the terminal in the UI - it is only impacting the UI.

However. It may be indicating that the resolution of the gcode file is too high to be printed. Can you share the file?

By the way:

Please test in safe mode to eliminate plugin issues.

BTW (although not completely necessary for the initial conversation here in this case, but good practice):

I have scaled down to 25% in size

I don't think there's a flat surface anywhere on that object. I think we need to also see the gcode output from the slicer as well as some details on the slicer (make and version). We may need details on the slicer settings used as well.

That's the STL model, not your gcode file.

Sorry, here is the G-code

I think you a right, here is the G-code

I use Cura v4.8

Tell us about the printer. Make, model, firmware source and version (i.e. is this the firmware that came with the printer or has it been changed).

If the printer supports arcs (G2-G3) then the plugin Arc-Welder provides over 70% reduction.

Is a Anycubic Mega Pro, and a use the firmware that came with it, I do not know if the printer supports G2-G3
