Update #24

Greetings again to our faithful (and patient!) backers!

Watch the video for the latest news and info on a number of subjects...and this one is a little shorter than the last one!

Here is a link to the new instructions page on

(we will continue to add more instructions/links to this page--especially build videos for the LC and the PLUS!)

Dropcam of Printbot HQ  on 24/6 not Sundays

My wife mentioned that this kickstarter feels much like a marathon...and we're in those last 6 miles...definitely the toughest part--but ALMOST there!

Thanks for all your support!
Brook & team

      Still haven't gotten mine; when will they ship?

      ATX trick with the jumper is working, tested that this week. Just wire pin 13 and 14 and make sure that max current is not exceeded on each used power rail (e.g. 12V). There was one report of a overloaded power supply that blow the printrboard microprocessor. Maybe Brook can specify the power maximal power usage of each printrbot type / voltage
      Pinout check here:

      Please update us about shipping state. How many are shipped yet? How many are shipped per week. When can we expect our printrbot plus?

      Hi - its been over two weeks and an update would be nice! Especially on the Printrbot+ LC models...

      Im one of them international Printrbot+ backers. I'm fine with getting filament instead of a PSU. If any 220 volt ~400watt ATX PSU will work, I got a dozen lying around. If modification is required, a little fiddling works just fine.

      In case I missed it - when is it shipping?

      @Ofir Dotan: I doubt this PSU you linked will work. Those are usually 12V@1.5 - 2.0 A and 5V@500mA -> probably not beefy enough for 3 steppers, controller AND the heat bed.

    8. Ofir Dotan on May 4, 2012

      Hi Brook, Thanks for the update. I am an international PB+ backer, and I am happy to get the extra filament instead of the PSU as indeed they are easy to find (whereas the filament is not as easy).

      I would like to know about the specs for the PSU so I know what I need to get (power etc.)

      I also would like to know if the power supply from this USB-SATA adapter kit would work

      Can anybody comment on this or recommend a power supply? Thanks.

      Honestly, (and this is only a personall preference) the box looks too much like a Makerbot for my taste. I think I'll be making a visit to my local Tap Plastics store.

    10. Mike C. on May 2, 2012

      Are the plans for the enclosure box posted somewhere? i know most of the parts are on thingiverse but I didn't see the enclosure.

      I meant power button* sorry about that one.

      The Xbox360 power supply was thought of in the early versions and I believe that Brook spoke about it in one of the updates. (For the record I don't work at Printrbot and I'm only going on what I've overheard in passing) The Xbox power supply wasn't up to the standards that the crew at printrbot was looking for and the availability of an ATX supply with a range of 250watts to 900watts was more up to snuff, as it would allow for more heatbeds/hot ends/printrboards to be used at once and all from the same supply. Plus, they just look a bit better than the standard 360 supply which has no power cord unless you open it up and add your own. :)

      WOW!!! Those cases look great! I can't wait to see more! Things are coming along rather nicely!

      Another international backer here - I can accept providing the PSU myself, that's not a problem at all. In fact I seem to recall, let's see, update #15 arguing that making use of an ATX supply is sensible as they easy to get hold of :-)

      I wonder if it would be possible to use an XBox 360 power supply.

      Ignore the negative press? OK. i was missing a hot end (Brook sent one within a week which was swell) but now I'm stuck with a dead motor. so I'm ebaying one. I'm considering this a solo operation now.

    18. Matija Nalis on April 30, 2012

      I guess some filament is better than nothing for us intl. PB+ users; we're gona need it anyway (although I was mostly going to use PLA in order to avoid ABS toxic fumes, but oh well).
      It does not look like he's going to be able to fit much of ABS in the package (to match the PS price), but it does show goodwill from Brook, so hat down to that.

      He listens, and he tries his best, and he responds truly, and that's what's the most important.

    19. Gianmarc Coppola on April 30, 2012

      Yea!!!! extra filament. You didn't even have to do that and I was still happy :) Thanks.

      Jason W. on April 30, 2012

      I'm more than happy as an international Printrbot + backer now, not just the replacement filament, but also how fast Brook post the response to the problem and the effort he put in to try to satisfy us :)

      THANKS BROOK!!!!!!!!!!!!!!!!!!!!!!!!!!

      Was planning on using a different power supply anyways, atx is just too big and ugly! lol

    22. Gavin Maxwell on April 30, 2012

      Great update Brook - keep up the hard work! As an international backer who received his PB late last week I think it's amazing what you've accomplished - so does everyone I show it to! So glad you're going to be at MF as well as I'll be travelling up from Sydney to attend! Can't wait to see the Jr and will be making sure I have a fistful of $$'s as I know I won't be able to resist! (hope my wife doesn't read this! :-) )

    23. MichaelAtOz on April 30, 2012

      Brook was really freaked out by the moth :) phobia? Someone there should print a couple of these and hang them above his chair... ;)

      My money is on the Jr having a bowden extruder, or two, one each end. I've been thinking of how to get a hotend to manage two+ filaments as input to extrude mixed colour....

      You know what would be interesting? A scheduled dropcam tour! Maybe an evening for those of us on the Eastern coastline so you'll still be working. Just tell us what we're seeing, talk to us about the bot farm, explain your work flow... etc. Just tell us what time you'll be doing it and hopefully Dropcam can handle the traffic!

    25. Tyler McNaney on April 30, 2012

      So I just watched the Dropcam for about 45min. Not sure what I was waiting for. The train sure does come close to the building.

      Great work Brook!

    26. Brett M on April 30, 2012

      Im in Canada... no worries about the PSU. I can get those pretty cheap here in Toronto. You adding extra filament in exchange for the PSU is perfectly fine for me! If anyone else in canada has a hard time finding a PSU, please contact me on the forum user name plexus and I will work to get you a PSU (you'll have to pay for it :). IGNORE THE HATERS! :) (does the printrbot jr print moths???)

      TEASE! Printrbot Jr sounds really cool... and it was just out of range of the camera. Nicely played :)

      See you at Maker Faire, Brook!


    28. Todd Lampone on April 30, 2012

      I very informative update, thank you. And while I am not an international backer I am certain that your offering of additional filiment will go well recieved. It should definitely help balance out the new out-of-pocket expense the international backers now have. They were going to need filiment anyway right? I am very, very, very excited about the printrbot JR. I purchased the printrbot+ but my goal was to create a regular printrbot and create a portable, self contained, 3D printing station. I have a feeling the JR. version is going to suit my needs even more so.

      brinky on April 30, 2012

      Thank you for the update. I'm a international PLUS backer. I accept your apology. But can you be more specific about the needed power supply? If I remember correctly you use two small 12V plugs?

    30. Brett M on April 30, 2012

      No worries Brook. Ship when you can. I am patient and when it comes it comes. I figured this would be a huge undertaking and I think you guys are doing an amazing job of it. There is a lot to learn and do and a lot that can go wrong and go right. More is going right than wrong and you and your team are working hard to make this a success. Don't sweat it and definitely don't sweat the haters, whiners and complainers.

    31. Marcus on April 30, 2012

      @Brook: I hope it all works out at the end with paypal and funds in general, hang in there- waiting patiently for my Printrbot. Even though I'm not a Plus-Backer I could live without a power supply... They are cheap to source here as well (germany).
      Great work, amazing shop, good luck.

    32. Simon George on April 30, 2012

      Thanks for the update. I think it's reasonable to buy the odd missing nut/bolt. Not shipping PSUs to international PB+ backers is a shame but the explanation makes sense and I think shipping filament instead is a good compromise - especially since the PSU would have the wrong cable anyway that the backer would have to source. I'm happy that shipping is moving forward, I backed late so mine will be very delayed but I expected that when backing such an ambitious project. I'm sure that everyone who has backed will get something great, even if it isn't 100% as expected or on time, but it will be worth it.

    33. J45on on April 30, 2012

      Great update Brook :-) as an international Printrbot + backer I am more than happy to get some extra filament instead of a psu.
      Your work is appreciated.

    34. Tim Watson on April 30, 2012

      Does anyone know where I can find the specs for the laser cut pieces?
