If this is an error that occurs when the extruder is operated, please raise the value higher if the extruder item has “max_extrude_cross_section:” . If you don’t have any items, add them and add enough value to drive them
The default value is calculated as nozzle ^2*4, so 0.4mm nozzle will be applied as 0.64
If you have a standard printer with a standard 0.4 nozzle, then this advice is simply wrong. Under normal operating condition this error does not happen. If it happens then something else is wrong.
