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
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
Step 2: Remove Cover
Remove the screws holding the cover on. This step may not be applicable for everyone. If you have a Solidoodle there are 4 screws. There will be two on each side, towards the front-bottom. There will also be two screws at each bottom corner at the rear. Carefully remove these four screws and lift the cover straight up with a slight tilt to the rear. At this point you should also have your printer powered and connected to Repetier Host. Under the Manual Control tab click "Heat Extruder". This will save you from having to wait for it to heat up later.
Step 3: Measure
Mark a 100mm segment on the filament. This can easily be achieved with a 100mm length of drinking straw or a steady hand. Take note whether the top or bottom of the mark signifies the correct length.
Step 4: Line Up
Set Extrude length to "1" and click the down arrow until your bottom mark is lined up with the top of the extruder [this can mean top of mark or bottom depending on your measurement/mark technique]. In my picture you'll notice the top of the mark is level with the extruder.
