D3D Ohio 9/17

​

  • Finished cutting and Assy. 1” dia pipe PVC frame 12”
  • On drilling holes, using drill press and just mounting a short idler to the side with a vicegrip as a guide was not accurate enough.
    • Produced and printed a 1” pipe drill guide; which works great!
  • Next is the good parts, when I have an opening... mounting electronics and getting it running!
    • 10/9 update So far, I’ve got to rebuild the extruder and discover / wire the stepper harnesses.
  • https://wiki.opensourceecology.org/wiki/Takacs_Ideas_Page for automation work I’m doing for an online store and manufacturing execution system. Think automated printing inspection and boxing of orders, scrapping of failed prints in fillastruder ect.
