[Sticky] Ender 3 Prints too high on z access
I have an Ender 3 pro that is about 6 months old and all of the sudden the prints, print too high on the Z-access. I have re-leveled the bed, replaced the bowden tube and the extruder and to no avail. A friend told me to calibrate the printer but I am not sure how to do that.
Too make it more mysterious, I bought a used 3 pro today as well to see if the problem was consistent. Strangely it happens on that printer as well, even when I print using the stl files that were already on the SD card with the printer. I changed nothing... I can't figure this out or find any reference to the problem. I printed a calibration cube and this is what it looks like.
