Move exceeds maximum extrusion when printing prime line with a 0.25mm nozzle
Got this error when ive switched to a 0.25mm nozzle.
Move exceeds maximum extrusion (0.289mm^2 vs 0.250mm^2).
Cant see anything in my printer.cfg that is the cause and my slicer is set correctly for the nozzle size (although this error is occuring during the prime line so shouldnt be effected by the sliced gcode).
Ive used the 0.25mm a few times before and not had this issue. What am i doing wrong? Ive attached printer.cfg
I know i can change the max extrusion amount but im guessing its an error in the cfg's that needs fixing. Haappened with primeline and primeblob (both just using the default settings, ive not edited any of the macros)

It's a limitation of the prime macros, my recommendation is to just leave nozzle_diameter under
[printer] at 0.4 for now.like-gold•15mo ago
ah thats a shame, i'll probably dissable the prime line if that is the case. Thanks for the help mik!
No need to disable, just set nozzle_diameter to 0.4 or higher in your config, it does nothing other than set the limit for that error.

Ah I see. I thought it might have more effects on things than just setting the max cross section limit but as long as I set my slicer line widths correctly it doesn't matter?
Exactly.
you can deactivate this sanity check
by setting it to 999
i dont say its a good idea
