Tutorial - Calibrating Extruder E-Steps - 3D Printing

One of the most crucial calibrations to get the best possible quality out of your 3D Printer. In this video I break the process down to its most simple form and show you how to do it.
The Formula is simple and here it is for reference:
Old E-Step Value * (Expected travel/Actual Travel) = New E-Step Value
As always, be excellent to each other and Happy Printing!

A word of caution here (something I just discovered after some frustration this afternoon): Make sure you are manually extruding SLOWLY! The default 'fast extrude' in Slic3r is 20mm/sec (1200mm/minute!), which is fast enough that the gear could be grinding on the filament when it tries to push against high built-up pressure in the heatbreak. I kept getting different readings every time I measured until I slowed the rate down down. For best accuracy, use the 'slow manual extrude' (single arrow on the button) in Slic3r or otherwise make sure you aren't getting erroneous results. If you can't get the same answer several times in a row or if your measurements seem to be way off, check the extrusion speed!

Great tutorial! really helped me figure out what i needed to do. Thank you.

Hi there,
which model is that 3d printer?where can i get more info about it?
Thanks.
Best regards

Can u please tell how your printer is called or it is custom made? As I see on your video list you had just suddenly changed the printer and never spoke about it.

Great instructional videos!
I suggest you take it one step further when calibrating extrusion by doing the "E Steps Fine Tuning" steps as described in reprap.org/wiki/Triffid_Hunter's_Calibration_Guide
You will get good prints following the guide in the video but doing the above mentioned calibration too takes you closer to perfection. =)
