Picture of How to calibrate the Extruder on your 3d Printer
If you're one of the many who have bought into the 3d printing craze you've probably realized they require a great deal of tinkering to get optimum results.  I'll show you how to calibrate the extruder in order to get better quality prints.  As you can see by the printed table above, a poorly calibrated extruder can have adverse effects on your prints.  These easy to follow instructions are great for beginners because all you need is about 20 minutes and some basic tools.  These instructions will be shown for a Solidoodle 2 but will work for any RepRap using Repetier Host.  The best part is, they require no permanent modifications.  Lets get started!

Step 1: What You Need

Picture of What You Need
Gather the following Materials:

- A No. 1 Philips Screwdriver 
- Metric Caliper ( Metric ruler will also work)
- Sharpie or other marker
- Pen and Paper
- 3d Printer
- Computer


- Drinking Straw
- Scissors

Thank you so much. I used this to calibrate mine and it worked great. you are so much help.

I have a Solidoodle and it works great I found that hairspray will help stop warping if you just spray it on build platform before print, also just add 15°c to the standard temp for bed/extruder.

Nice job. I gather from the screen shots that there are other possible calibration options to look into as well, perhaps you could expand on the instructable with any suggestions for doing calibrations for x/y/z movements, or the like. Presumably that's stuff done during initial setup, but as a printer ages, you may find it useful to recalibrate those as well I would think.

Yea, if I could afford one!

Nice Instructable. I just purchased the Solidoodle 3 and awaiting its arrival. I will be following your instructions. Also I hear you must level the table with the extruder as well. Have you done this also?

you lost me at this step. Where does the config button come from? Where is this dialogue page located?
Is this part of pronterface? Is this a specific application for modifying the marlin settings without recompiling/pushing to the arduino through the arduino ide???

This tutorial does not use prontorface. The screen shots you are seeing are from Repetier Host. I've added a picture to clear up confusion, other wise you can edit the config.h in your firmware of choice.
