Skycam debugging II, first test movements

I tested each drawbot separately with the new skycam drivers and – after several hours – found a one letter typo that was messing everything up. Then I decided to re-read the critical sections and found two more. A-ha!

Once each Drawbot was moving correctly in their planes, I reconnected them and began moving in all three dimensions.

I added a way to invert the rotation of a single motor because I wound the string backward and it was easier to flip the code than rewind the bobbin.

Right now it’s convinced that 12:00 is X+ and 3:00 is Y+. Not fatal but not what I expect.

Here is a model for a plotter you can use to safely attach a camera to your Skycam. If anyone buys a skycam in a kit I’ll be sure to send one of these along.

Here is some early video.
