Move exceeds maximum extrusion error with 2.7.1  

Move exceeds maximum extrusion error with 2.7.1

Hello, 

I'm sure this is a common question but what I am reading isn't really helping me understand why this is happening right after I upgraded Prusa Slicer 2.7.1. Don't see this issue with any of the other slicers I try (Super Slicer, Orca).

"Move exceeds maximum extrusion (8.947mm^2 vs 0.640mm^2) See the 'max_extrude_cross_section' config option for details"

Using a Rat Rig V-Minion (Klipper-RatOS). This is what the Start Gcode is showing but don't recall adding.

"M190 S0 ; Prevents prusaslicer from prepending m190 to the gcode interfering with the macroM109 S0 ; Prevents prusaslicer from prepending m109 to the gcode interfering with the macroSET_GCODE_VARIABLE MACRO=RatOS VARIABLE=relative_extrusion VALUE=TrueSTART_PRINT EXTRUDER_TEMP=[first_layer_temperature] BED_TEMP=[first_layer_bed_temperature];enable this if you have a BTT Smart Filament SensorSET_FILAMENT_SENSOR SENSOR=my_sensor ENABLE=0"

Is there something in the start code I need to change to keep the error from showing? I do have the use relative e distances checked.

Thank you in advance,

Paul
