+====== Orca Calibration ======
+{{tag> tuning setup about Resources}}
+Proper calibration of the Filament Profile is essential for good prints. Orca slicer has several built in calibration tests to assist in determining the specific profile values.
+Specifically you should calibrate for each of your filaments:
+  * max volumetric flow rate
+  * flow ratio
+  * pressure advance
+  * extrusion temperatures
+A great guide that would be hard to do better in terms of explanations is at  https://www.obico.io/blog/orcaslicer-comprehensive-calibration-guide/
+For calibrating flow rate, I prefer the following calibration test over the Orca test as it’s less subjectively focused and more functionality focused, uses way less filament and prints quicker: https://www.printables.com/model/1113488-flexi-flow-calibration-tool-v4-by-ck3d
+Additionally you may want to perform some experiments to address overhang and bridging settings.
