Move exceeds maximum extrusion (2.673mm^2 vs 0.640mm^2)
Trying to print some basic stuff and getting the following message:
Move exceeds maximum extrusion (2.673mm^2 vs 0.640mm^2). Nozzle in slicer is 0.4 as well as in RatOS.cfg file. The print stops during prime blob, so i think it is not related to sliced file.
Any help are more then welcome

in order to make it print i have to use max_extrude_cross_section = 9999 in my config
This is RatOS 2.1 on RatRig 3.1 300mm
Are you using relative or absolute extrusion?
I am using Start G-Code and all instructions as per RatOS instruction page. Nothing else
I had this issue with idex

In 2.0 you need to set
variable_relative_extrusion to True in the [gcode_macro RatOS] section for relative extrusion to work.
You can either do that in your printer.cfg or you can do it via gcode before START_PRINT in your slicer like so:
this is for RatOS 2.1 in which case relative extrusion should be the default (EDIT: i thought i made this change, but apparently i didn't - it's only True by default on IDEX printers (VC3.1 IDEX and VC4 IDEX), because wipe towers don't work in absolute mode).
What nozzle size are you using and did you set it correctly in the RatOS configurator on the hardware page?
Nozzle in slicer is 0.4 as well as in RatOS.cfg fileAh, it's already answered here. You still need In 2.1
I will try this, thank you for a hint!
