Hareware isn’t everything

With Charles Pax’s recent proof-of-concept of a motorized conveyor belt print platform, we’re going to need some software/firmware changes to make full use of these improvements:

  1. Queuing print tasks
  2. Removal/auto-wiping of the test extrusion
  3. Moving the print platform to the front/back/side of the MakerBot for ejecting the finished print
  4. Ejecting the printed part
  5. Returning the platform to 0,0,0 / center

From the video posted on Charles’ site, it looks like he’s managed #3 and #4 already.  The extrusion path around the print that we see in Nophead’s prints probably would work at #2.  I also seem to recall some (such as Zaggo?) have mounted a toothbrush head on the build platform for auto-wiping of the extruder head.

Returning the platform to 0,0,0 is an interesting proposition.  This would seem to work best once the opto-endstops are installed.  I’ve got my set of six fully assembled opto-endstops sitting in a box next to my MakerBot because I haven’t really needed them and they tend to get in the way of printing.  Although the opto-endstops have been removed from the standard MakerBot kits, I think we may now start to see them returning.

MakerBot Conveyor Belt!

Charles Pax has developed a working MakerBot motorized conveyor belt print bed.  (Is it heated?)  There’s a lot of reasons why this is a big deal:

  1. This is the fourth MakerBot “milestone.” We’ve reached milestone #1.  Milestone #2 (different threaded rods and internal electronics) and #3 (Gen 4 electronics) are noble, but not really transformative goals.
  2. Continuously cranking out parts is a way to turn a simple MakerBot into a portable factory – rather than a modest means of prototyping.
  3. Unattended printing is one of the criteria for the RepRap / Kartik M. Gada Humanitarian Innovation Prize.
