I’ve seen this tips before (and I even added one of these to my “shopping” list), but as I’ve never seen/used one of these before, how should it be used?
You do the 1-2-3-4 calibration, changing the z-axis until the nozzle touches the feeler? should it be able to slide (push?pull?)?
I fear that it even with a consistent and rigid thickness the process would still require some guesswork, and prone to human error.
