Printers have labels attached to them for identification

Good stuff to document in time:

  1. Identifying and clearing jammed extruders
  2. Manually leveling the bed
  3. Setting up a new computer for 3D printing
  4. Optimal Slicer settings

UP! Mini

Printer status as of 1/3/2018:

Name Status Notes
Animal OK Some oozing issues but otherwise OK
Kermit BAD Prints are very garbled Currently not powering up.
Dark Helmet ? ...

Several original UP! Minis were donated by Maker Lab at Harold Washington Public Library in October 2017. 3 of them should be fully functional; 2 are incomplete and are for parts/hacking; there may be more on the way. The machines are being researched and documented.


  • The UP! Mini was created by PP3P, which was later acquired by Tiertime. Tiertime continues to provide support for the original UP! Mini, but you are likely to encounter both names, as well as UP3D.
  • There are two software packages out there that control the printer. Installing both is recommended:
    • The older UP! software has a traditional Windows interface and includes 3D files (in a proprietary UP format) for some plastic replacement parts for the printer (such as extruder mountings and spool holder). It assumes that you print with UP! brand ABS and doesn't allow you to change things like filament temperature without 3rd party hacks. The software is no longer developed and stops at version 2.18.
    • The newer UP Studio software has a more modern, simplistic Metro Windows interface. It lacks some of the features of the older software, but allows you to adjust things like filament temperature settings (if you register an account with Tiertime). It's being continuously developed and is currently at version 2.0+.
  • Extruder lights don't work on some machines for some reason. probably firmware related. All but one machine run the correct firmware, which doesn't switch the lights automatically. The lights are switched by very slowly double-pressing the power button on them. The machine with the wrong firmware turns the lights on with a single press and dims them after a minute.
  • This is a good filament guide for the Mini - https://www.thingiverse.com/thing:2593558
  • This wedge is suggested to make the extruder assembly not fall out - https://www.thingiverse.com/thing:2630148
  • Here is a good teardown of the printer, in case we decide to hack the non-functioning ones - https://www.eevblog.com/forum/reviews/3d-printer-teardown-%27take-two%27-the-up-mini-3d-printer-by-pp3dp/
  • Here is a 3rd party CPU option - https://www.thingiverse.com/thing:1655144/#files
  • Advantage: a stock Mini in working order prints (UP brand) ABS fairly reliably with UP software.
  • Disadvantages:
    • Requires a PC connected via USB to control print jobs. Tiertime offers a $250 CPU upgrade which brings WiFi and a few other features to the printer. 3D party CPU replacements are also available.
    • Works best with ABS, especially its own brand. Getting it to work well with other filament is TBD.
    • Maximum print volume is 12x12x12cm. Layers with a large surface area tend to fail due to delamination.
    • Extruder is magnetically attached to the X-Y gantry. It makes it easy to remove for servicing and reduces likelihood of damage, but also makes the extruder easy to misalign. 3D party extruder assemblies exist
