max extruder cross section exceeded
just finished a vcore 500 (old version. kit sat in storage) and im trying to do the first prints.
went through the configuration will all the # signs in the config file. when i try to start a print (through super slicer) the head will print the puge skirt around the object but as soon its done the print cancels a nd this message is displayed (pic).
on superslicer im using the deafult vcore 500 setting or whatever its called.(only changed the start g code per the ratos manual)
so far i tried-
switching to cooled steppers in config.
reslicing.
slowing down the print speed to 10%.
im trying to gather as many things to try as possible before im back at the workshop next week.
any and all help will be greatly appriciated. feel free to dm me.

you need to make sure it matches what you have defined in your slicer

ill add that i couldnt find anything about cross section in the config files
both need to be either relative or absolute

ill add that to the list thanks
any more suggestions will be greatly appriciated
It is a slicer issue - your slicer is telling klipper an unreasonable amount to push through the hotend. What slicer are you using?

super sllicer as i said in the post. "stock" vcore setup
there is no "stock" slicer

i mean the settings provided in the slicer for the vcore 500. where u can choose what printers you got first time that you boot the slicer.
are there any other fixes/problems you can think of? again im trying to collect as many things to try as i can before going back

I had similar problem while using arc welder plugin.
Look at this: https://www.klipper3d.org/Config_Reference.html
Especially this part:
#max_extrude_cross_section:
Maximum area (in mm^2) of an extrusion cross section (eg,
extrusion width multiplied by layer height). This setting prevents
excessive amounts of extrusion during relatively small XY moves.
If a move requests an extrusion rate that would exceed this value
it will cause an error to be returned. The default is: 4.0 *
nozzle_diameter^2
#max_extrude_only_distance: 50.0
Maximum length (in mm of raw filament) that a retraction or
extrude-only move may have. If a retraction or extrude-only move
requests a distance greater than this value it will cause an error
to be returned. The default is 50mm.

This is my max_extrude_only_disatnce override to enable arc welder.

Thought that extrude only is for.. only extruding. So not while printing
But thaks alot ill add that
