When I try to make a square as shown in you example; 0,0-50-0,0-50-50,50, it looks like the picture.
I tried a few things, adding the 180 in the program, reversing the motors positions, reversing the motor plugs, using different values for ARMLENGTH. It still has problems. One thing I did not understand, how did you align the motors with the arms? I just made the motors potion at 90° and lined the arms up in the middle.As you can see in the picture, the arms are longer the the Popsicle sticks in your example, it is 125mm from motor to motor.

Thomas,I could not get it to work .The X, Y coordinates fail to come out right. I tried 0,0 - 0,50 50,0 - 50, 50 to make a square but it comes out more as a big triangle with 0,0 and 50,50 going to the same point.Also, I notice the servo motors are mounted with one upside down in some pics and the same in other pics. -Thanks

This would make a great car cup holder.Just mount it on the dash and have it sense the car's motion.It should hold the cup perfectly steady!

I've made this for a few years now, except I did not use heat to evaporate the red liquid, just room temperature. After it's burned, it will go from a reddish-brown, completely non-magnetic solid to a black, magnetic dust. The material can actually burn on it's own, like an incense that emits formaldehyde. I have to wonder if I made a peroxy-acetate instead of an acetate.
I did too, lot of fun!
