Algodoo

Nicely done, but does not work with the latest version of Algodoo, which is now free. I was able to get it to work by moving the wheels closer to the rods, which creates more friction.

Just curious, why do you double-up your variables in all of your scripts? For example, you write:

scene.my.x1 = scene.my.x1 = 4.7

You only need to write: scene.my.x1 = 4.7

Anyhow, I ran the printer, and it doesn't seem to print anything other than a few squiggly lines. What is it supposed to print?

EDIT: I tightened the rollers so that they don't slip on the rails (as s_noonan suggested) and now the printer prints a 3D image of a cube (which is probably what it's supposed to print).

I'm not the pro but this is my fantasy and simply did not do a different))
