See the 'max_extrude_cross_section' config option for details
Anybody know where this setting is? I couldn't find it in the extruder section. New Orbiter 2.0 and its not extruding so trying to calibrate with Orca.

it is in the
[extruder] section
https://www.klipper3d.org/Config_Reference.html#extruder
The default is: 4.0 * nozzle_diameter^2
@blacksmithforlife 🇺🇸 Where would I change that? printer.cfg?
yes
@blacksmithforlife 🇺🇸 max_extrude_cross_section: 100 so it wouldn't error?
what error are you getting? 4* nozzle diameter^2 is a reasonable default
@blacksmithforlife 🇺🇸 I had the wrong extruder selected. My 2.0 is the second one listed with a different motor
@blacksmithforlife 🇺🇸 But thast wasn't the problem. Still getting error. Move exceeds maximum extrusion (6.319mm^2 vs 1.440mm^2)

what size nozzle are you using?
.6 on Rapido UHF
and did you set your printer.cfg nozzle size?
Yes
and what is it set to in the slicer? You are trying to extrude a lot of material, I doubt that is going to work
Sorry but I don't know where to find that in Orca.
I've made no changes to the stock settings in Orca.
@blacksmithforlife 🇺🇸 Now I'm trying Prusa Slicer with a calibration file.
Did you make sure your slicer and your printer.cfg are both configured for relative extrusion (or both configured for absolute extrusion)?
@blacksmithforlife 🇺🇸 I copied this from a previous printer.cfg when I had the printer working well. All I've been trying to do, now going on two weeks in changing extruder to Orbiter 2.0 and hotend to UHF. [gcode_macro RatOS]

I copied this from a previous printer.cfg when I had the printer working wellwas this from upgrading from 1.x to 2.x?
Upgrading what from 1.x to 2.x?
ratos
Extruder, hotend, RatOS?
I've always runs 2.x
great
what is
variable_relative_extrusion set to in your printer.cfg?False
and what is it set to in your slicer?
If that says "use relative e distances" it is checked
and you have a disconnect. It needs to be checked and
variable_relative_extrusion needs to be TRUE or it needs to be unchecked and variable_relative_extrusion needs to be FALSEWhich is better?
it is recommended to set
variable_relative_extrusion to TRUEI reinstalled RatOS yesterday when I couldn't get anything to work. Now its sortof working but the prints look horrible.
Hopefully, that fix will get me going. I liked soem of the other features like Exclude Object and Adaptive Mesh. Guess I need to go back to first grade and work up from there.
