This was fun to follow along. Just got myself a 3-d printer and reading things like this is inspiring.

Thanks! I only recently got one too, but it's been really useful for projects. Which did you get?

Prusa i3 MK2 from a friend. Works OK -- can't compare it to anything else.

Maybe it's a dodecapod?

Since I was just doing this stuff yesterday with a Raspberry Pi with a stepper motor HAT, that being driven through I2C, and his choice here being PWM modules, does anybody have a reference comparing the latency of different motor-driving approaches?

Haha I guess it's a as-many-legs-as-you-want-to-print-apod!

The PWM modules are also driven through I2C. Do you mean the latency between the sending the command and the motor doing it?

Oh neat! I made the centipede. I didn't realize someone posted this until I saw some traffic from HN. It's a work in progress, I have some fun plans for it.

Let me know if you have any questions or feedback!
