    Description

    You shouldn't calibrate the steps/mm setting for any axis other than the extruder.

    Unless, of course, you have a very large printer (300mm and above) or are using something like spectra line instead of timing belts. In that case, print the largest scale test that fits on your print bed, oriented in the direction you want to calibrate. Keep in mind that the test parts are slightly larger than their nominal size.

    Then measure the distance between the holes in each end, preferably going from the 100mm spot on your tape measure upwards. Or use any other precision measuring device that you feel comfortable with. If you can match up the distance between the holes by eye to the measuring tape (or other measuring device), you're close enough. FFF 3D printers are not precision machines, so the error of matching is negligible compared to the base accuracy of the printer itself. Measuring holes instead of outer dimensions ensures that a (slightly) miscalibrated extruder or other errors won't affect the final measurement.

    You can calculate your new steps/mm like this:
    [old steps per mm]*[nominal distance]/[measured distance] = [new steps per mm]

    needed tweaking of the steps :) thank you for this
    Feedback:
    printer calesthenics for each setting and the math for updating speed.. to tune the software and ahrdware.. a way to find the real limits of your printer.. not just guessing to get something to work but how fast youc an do each type of move.. and to define them in the printer profile.. so that printing can be simple as chosing speed or quality balance slider instead of every miniscule step

    Should we measure between the two notches - or inside diameters of the holes?
