[title] Preparation
-[* 9] If you have set up a different extruder steps/mm value than stock in the past I recommend resetting it to its default.
-[* 10] We recommend a micrometer instead of a caliper for the following steps. Calipers are not precise enough to measure such small values and a micrometer has a ratchet system made to apply same pressure for all measures.
+[* 9] If you have set up a different extruder steps/mm value (e_step) than stock in the past we recommend resetting it to its default.
+ [* 10] E step calibration isn't a reliable way to calibrate your extrusion because you are not measuring where it matters.
+[* 1] We recommend a micrometer instead of a caliper for the following steps. Calipers are not precise enough to measure such small values and a micrometer has a ratchet system made to apply same pressure for all measures.
[* 10] If you still want to use caliper, make sure to always use the same pressure when you measure and don't press too strongly.
-[* 11] If you like to buy a micrometer, choose a quality one. Digital micrometers are not necessarily more accurate and precise (especially if it is a "no-name"). We can recommend Mitutoyo 102-301 for its low price and quality. Some recommend brands: Mahr, Tesa, Starrett.
-[* 9] Make sure to not change the printing temperature during these steps. Temperature might change the flow and therefore the extrusion multiplier.
