• mk 4, version 30

  We hit the "Fusion" version of 30 just as we printed the latest model - it was interesting to find out that the fusion 360 model posted earlier in the logs stays up to date with the latest changes. we're figuring out how to version control between that, the thingiverse page, and this; such will be a problem to solve. The first match was last night, video to follow

  It seems like the XIAO esp32c3 does better with the PWM on channel 9, rather than 10 or 7. Still trying to figure out how to run two servos at the same time.
  
  Running this test code to try out different pins for the XIAO:
