Simply Feet for Ender 3

thingiverse

I'm using a simple feet calibration method for my Ender 3 with Styrofoam. It's easy to do and works well. Just place the printer on top of the Styrofoam, then use a ruler or caliper to measure the distance between the nozzle and the bed. This will give you your zero point, which is essential for proper calibration. Next, adjust the height until the extruder just touches the bed. Make sure it's centered and even. After that, run a test print to ensure everything is working correctly.
