Hi, I’m getting Move exceeds maximum extrusion (7.920mm^2 vs 5.000mm^2) I understand that it’s usually the slicer but I don’t see it. I’ve been using this SuperSlicer profile for weeks. Printer.cfg , log is here. . Also why is the max so low? Ender 3 with stock extruder and hotend. The config is no…

Did you maybe by mistake switch to relative extrusion in your Slicer or start code?

I did remove the start gcode from SuperSlicer and added START_PRINT and END_PRINT macros, BUT the same happens when I revert to default in SS and re-slice… The START_PRINT macro is as such: [gcode_macro START_PRINT] gcode: {% set BED_TEMP = params.BED_TEMP|default(60)|float %} {% set EXTRUDER_…

Could you try using a M82 in this macro to force absolute extrusion? Otherwise set max_extrude_cross_section to something above the complained value.

I have reverted the slicer starting gcode to default, re-sliced, added max_extrude_cross_section: 6 to printer.cfg, restarted everything, yet I’m still getting this seemingly randomly (now even lower! Move exceeds maximum extrusion (now 2.546mm^2 vs 0.640mm^2 at layer 10))

Set it to 50 and put M82 into the start code/macro.

[image] LifeOfBrian: Set it to 50 This is not a correct solution. Apparently extrusion values are adding up to an unhealthy amount and Klipper rightfully complains / shuts down. Just ignoring it (by effectively disabling the sanity check) will likely have other unwanted consequences.

Then M82 should do the trick as it did for me. Thank you for the correction!

I’m still not sure what to do with this even after reading all of it. My errors didn’t happen during priming line, it was seemingly absolutely random with the same Gcode. It happened with default Ender 3 profiles in SuperSlicer. Do I just have to put up with prints randomly stopping mid multi-hour p…
