18/21… meh! 
On second thought, not too shabby for a test result in an area I took up less than six months ago. 
For those unsure of which answer they got marked incorrect, now is your opportunity to argue with me - I added answers/cheat sheet 
19/21, that cw/ccw nut and a mixup of what is X and Y on a i3*got me… 
@Chris_Garrett No answer to question 21?
@Adam_Steinmark oops! I was sure I added it, will fix that now
Ohhh, stray DIV - thanks for letting me know
16/21
And I have barely seen a 3d printer print a drone arm and a flute
18/21
20/21 that was fun
- Now let’s go see what I can learn.
21/21 not sure if I’d agree with the 2 pilars for leveling x axiz but it’s the only answer that kinda made sense. Never done it that way.
Got 21/21, but I’ve also not heard of using pillars to test a single axis. I would’ve said X/Y. And honestly on the blobby box I’d still reach for the belts first, since it’s an easier check than extrusion consistency. =)
20/20 and the pillar one is nonsense and doesn’t work this way.
Nonsense @Rene_Jurack ? That’s how many Wanhao and Ordbot owners level their X axis so I am wondering why you think it’s nonsense …
@Tim_Visible multiple answers on that question score a point, all explained in the answers page that is linked from your result
Here’s one example of the pillars, the one I printed for my Wanhao. http://www.thingiverse.com/thing:1138928
Here is another option that goes on the Y rails also http://www.thingiverse.com/thing:1374915
Prusa version http://www.thingiverse.com/thing:280974 (as stated in the answers page, on the Prusa Mk2 we send the z to the top and grind the steppers a few times to do the same thing)
17 out of 21 and I actually don’t know what I am doing.
@Chris_Garrett Ohhhh, they’re tools, not calibration prints. Now I get it. You wacky cartesians, you. =P
@Tim_Visible ha!
