E-Step Buddy

This tool helps you easily measure the amount of filament being extruded. Simply mark the top slot with a permenent marker, then extrude 50mm. Measure the difference between the two marks to get your e-step offset. Then get your new e-steps per mm with this equation

(Current E-Steps Per MM) * (50/(50-offset))

Make sure to get the sign of your offset right.
