ERROR "Move exceeds maximum extrusion (0.699mm^2 vs 0.640mm^2)"
Hello all. Could someone please steer me where I should start looking? First time I see this error, VC4 500 mm, almost 2000 hours printed. Error happened during the print process

@armearme. Have you had any help on this? I'm facing the same issue.
I don't really remember what I did, but I found the answer here on discord. it was something about the config file, if I remember it correctly...
Hey @armearme. @Mr_Phelps_VCore_4.0_500 , so the error actually means that the extrusion volume exceeds the default setting(not in the printer.cfg somehow, I guess it may lie in the modular extruder configuration file of RatOS).
I guess that the sliced gcode somehow exceeds the maximum extrusion volume, which triggers the error. Something I also experienced when using larger diameter nozzle.
So, to solve that, you just need to add the larger max_extrude_cross_section value to youe [extruder] section of the printer.cfg.
You can find how to add the config in the TeachingTech's adaptive purge tutorial

Okay, makes sense. And what value shoud I choose?
Well, 2~2.5 will be sufficient. During the use of the printer, will not exceeding that much of extrusion volume during printing, except doing insanely amount of purging.
