Describe your issue:

Im having issues when starting prints, purge line works fine but after the prints stops,
in klipper it gives the following error “Move exceeds maximum extrusion (56.309mm^2 vs 50.000mm^2)
See the ‘max_extrude_cross_section’ config option for details”
Can someone help me out pls

I am using cura,
start GCODE:
START_PRINT BED={material_bed_temperature_layer_0} EXTRUDER={material_initial_print_temperature}

end GCODE:
END_PRINT

It looks like my gcode should be fine, can someone help me?

The error typically is caused by:

  • Extreme settings for the prime line in the start gcode
  • Extreme settings for a purge, e.g. on filament change
  • Crappy gcode created by the slicer (especially S3D)
  • Weird Slicer settings affecting the extrusion or flow rate
  • Misplaced M83 commands (e.g. in start gcode) causing the extrusion to add up

Umm, did you actually read the linked post? Hint: Point 5 in the list

Made sense, looked at the cura original start GCODE and changed mine from there, thanks
