<p>I'd spent a lot of time trying to get my e-steps right, after enough I made this tool.</p> <p>You put a bowden/reverse bowden in one end, and feed the printer from the other (you could just as well put it in a bowden feed to the extruder).</p> <p>To use the tool, use a fine pen to mark the filament in the first window. Feed a known distance (10mm starting out, 50 for fine tuning) and see where the mark stops.</p> <p>If you feed "10" mm, and you're one window too far, your extrusion multiplier is 20% too high. (2mm/mark, 10+2 = 12)</p> <p>If you feed 50 and you're a half mark too low, you are 1/50th or 2% too low.</p> <p>In the picture I show a 4% error (2mm/50mm).</p> <p>You can get away with leaving this in the printer's feed permanently, though there can be a little drag. The screw hole will let you hang it from the printer - I leave mine mounted most of the time, and just run the filament through it when I need to cal.</p> <h3>Custom Section</h3> <p>Post your makes!</p> <p>And if anyone knows what I was thinking with M Div 1.6 W, let me know, cause I forgot!</p> Category: 3D Printing Tests
