What is it?
This is a very compact test and calibration model for printing. It's goal is to show, if material sticks to bed and to show if oozing is occurring over several distances.
What is the reason in it?
Main goal was to make a calibration test as tiny and effective as possible
Save as much material as possible
Save as much printing time as possible
Show useful test results for retraction and printing quality
- Only include the most important and basic tests for proper calibration (in my opinion)
Why this and not others?
There are plenty of other test models out there, either with a very big range of tests, or just one test. Usually they are using a lot of printing material and printing time. However I just wanted to make a quick check, if printing results are okay. Mostly I faced difficulties regarding temperatures, oozing and only wanted to fix that (as this will solve basically all my issues). But that includes to change settings and print again, which will be quickly very long-lasting and annoying. Found for example a mini-test (http://www.thingiverse.com/thing:23550), but it didn't include printing over variable distances (oozing can be different at different distances).
What is in it?
In the end I made my own model which was already reworked several times and now ends up with following properties or "features":
Can be printed in less than 10 minutes (depends of course on printer speed, mine can do it)
Only using 0.67g of material
Showing oozing results between 10, 20, 30, 40 mm distances
Check, if retraction settings are too low or too high. (If too low: Oozing/Stringing; if too high: Bad quality of towers and printed numbers)
- Showing, if print sticks to bed well (first layer should have a clean and defined shape with no string/layer issues)
