      Maybe you could work with the RoBo 3D team that currently have a project running?

    2. Ken Schmitt on September 30, 2012

      any thoughts on another batch?

    3. Billy Zelsnack 2-time creator on September 20, 2012

      I'm doing batches and the plan is to make each batch larger than the previous. So the spots will change at least 5 at a time in the future.

      As for right now I have finish and tested my design changes for this batch and will begin printing the new version parts for the next 5 kits tomorrow.

      I'll try and do a better job of posting to the g+ project page.

      Dear Billy,
      it is possible to get the last shipped spotnumber may be every to weeks so we see a little bit of your progress?
      Thanks a lot Dag

    5. PaulMakesThings on September 11, 2012

      That's good enough, the E does stand for "estimated" after all. Thanks.

    6. Billy Zelsnack 2-time creator on September 11, 2012

      I wish I could give out ETAs, but I still just do not have a good enough handle on production to give out accurate estimates. The closest thing I am semi-comfortable saying is that I think that 2 kits per week is doable. At that rate your order number would end up being 3 months out. If that's too far out just send me a message and I'll give you a full refund. It's not a big deal. In the future when I have things better under control you're welcome to jump back in if you like.

    7. PaulMakesThings on September 11, 2012

      Any chance of an ETA? I've read through the blog looking for it, but other than a mention that your rate is about 2 a week, I don't see anything. I'm willing to wait, but I'm curious if were talking about something like 3 more weeks or 3 more months.

    8. Billy Zelsnack 2-time creator on August 4, 2012

      Only the first kit has been shipped at this point. I was planning on 4 for this batch, but I do have 3 other kits with most of the parts printed/cut. I am not ready to send out kits of loose parts yet so I will be doing some of the assembly before they go out. Hopefully less than to the sub-assembly level because assembly from loose parts can be very time consuming and I only have so much time available a day for each of my work sessions.

      Once this batch goes out I intend to do another Kickstarter update, but in the mean time if you're not following my g+ projects blog I post most every day.

      How much kit was shipped currently?

    10. Billy Zelsnack 2-time creator on July 17, 2012

      I should have the first kits shipped by the end of July as specified by the campaign. The plan is to make some assembly videos and ship the production 1 kit very soon. I will then be building multiple sub-assemblies with a different sub-assembly each day. I don't know how many sub-assemblies I can do in a day, but for the first run I am going to do as many as possible to find where my bottlenecks are.

      James Chamberlin on July 16, 2012

      Will you have all of the kits out by the end of July?

    12. Dag Geisler on June 29, 2012

      Yes they only have pics from makerbot.....

    13. Billy Zelsnack 2-time creator on June 28, 2012

      Cool. Thanks for the heads-up.

      haha. Looks like they got the pictures mixed-up.…

    14. Dag Geisler on June 28, 2012

      Hello Billy,
      you are on the German CT Magazin Website .....
      here is the link

      cheers dag

    15. Billy Zelsnack 2-time creator on June 18, 2012

      If the Internet connection is good I expect I'll post from the show.

    16. BoriSpider on June 18, 2012

      We demand pictures and video(if possible) :D

    17. Dag Geisler on June 18, 2012

      Billy thats sounds good....

      have fun cheers Dag

    18. Billy Zelsnack 2-time creator on June 18, 2012

      It's going well. Amazing how many little details are involved when moving from a prototype to something you can recreate at even a small scale.

      I have the Kansas City Makerfaire next weekend where I should have production kit zero as well as the prototype. After that it's all about cranking up production and getting the kits out the door.

    19. Josh Gribbon on June 18, 2012

      Hows the project doing?

    20. Missing avatar

      Dominic Wild on June 9, 2012

      Ok then I will build a second 3D printer :D.

    21. Billy Zelsnack 2-time creator on June 8, 2012

      I bought a pound of PVA a few months back. It's definitely on my research todo list.

      If you went the bowden route for the second extruder, as is my current plan, then the current setup should be fine to modify. If you are very serious about experimenting with a second extruder then send me a message and we can talk about getting you a RAMPS board with a 5th driver for your kit. Even so, it might be useful to do your experiments on a different printer because it is a HUGE hassle to do 3D printer research without having more than one 3D printer. Constantly bootstrapping a machine can be quite tedious.

    22. Missing avatar

      Dominic Wild on June 8, 2012

      The real question is not if it can handle it but whether it would be hard/expensive to modify it. Also if I would need another controller or it can already support another extruder (and if we need another controller, if it's possible to just get a driver and connect it separatly).

      I don't actualy need explication to do it, I just want to know if you think it worth it or if it's would be better to actually build a second one better suited for that.

    23. Missing avatar

      Dominic Wild on June 8, 2012

      Yeah I actually want to use it with a material like that:

      This way you don't have to cut everything and you can make more complexe shape too, like a sphere in a sphere.

    24. Billy Zelsnack 2-time creator on June 7, 2012

      The motor on those are the larger and heavier Nema17's. Two of those would be really heavy. The double pulley arrangement on the Printxel doubles the torque of the Nema14's, but I don't know how fast you could push two of those around.

      I think dual extruding is definitely interesting. Not so interesting for colors, but for a second type of support material. I have some ideas for implementing it, but that'll have to wait until after the kits are out the door.

    25. Billy Zelsnack 2-time creator on June 1, 2012

      The plan is for the filament pack to be 1lb of a single color and then a meter maybe of a bunch of whatever colors I can get my hands on.

    26. Missing avatar

      Dominic Wild on June 1, 2012

      Which color do you plan to include as a sample?

    27. Michael Hodges on June 1, 2012

      Woohoo "funding successful" congrats!

    28. Billy Zelsnack 2-time creator on May 31, 2012

      PaulMakesThings. Are you talking about the slicing and host software? I currently prefer KISSlicer and ReplicatorG, but I do regularly use others and will provide setups for the popular ones.

    31. PaulMakesThings on May 31, 2012

      Are you making it with any particular software in mind? What software are you testing it on?

    32. Billy Zelsnack 2-time creator on May 31, 2012

      USB cable. I see no reason why the Raspberry PI could not be made to work, but it would be cool if it printed its own case.

    33. Missing avatar

      Dominic Wild on May 31, 2012

      How do we plug this on a computer? Is-it with a USB cable or do we need a serial port?
      Also do you think I could control it with my Raspberry PI? (It could print his own case :D)

    34. Billy Zelsnack 2-time creator on May 30, 2012

      Josh. It's so close to the campaign funding date now and there is only one pledge left that might need updating so I don't think there will be many more if any.

    35. David Kononen on May 30, 2012

      Been sitting at the $1 mark waiting for an opening, yes! However, I just read the comments below regarding a KS error, just hoping I picked up one of the original 25 printers and not another unexpected unit. Thanks!

    36. Josh Gribbon on May 30, 2012

      You might want to change the description so it says "sold out even if it says its not" or something like that

    37. Billy Zelsnack 2-time creator on May 30, 2012

      Josh. Yes, you'll both get your kits. Don't worry about it.

    38. Missing avatar

      Dominic Wild on May 30, 2012

      I hope it's not yours:P.

    39. Josh Gribbon on May 30, 2012

      But just to clarify we will both still recieve kits?

    40. Josh Gribbon on May 30, 2012

      Does that mean even though i am currently listed as "no pledge" i will still recieve a kit? I think you got mine dominic, haha

    41. Billy Zelsnack 2-time creator on May 30, 2012

      Josh. From my Kickstarter emails I can tell how long a spot was open. The spot you grabbed was open for 25 minutes. Dominic. The spot you grabbed was open for only 3 minutes.

    42. Billy Zelsnack 2-time creator on May 30, 2012

      Hi Dominic. Thanks for the offer, but you grabbed a spot fair and square according to the campaign rules. I've still not heard back from Kickstarter about their crazy bug. Hopefully they'll resolve it soon because I can imagine other campaigns where additional unexpected rewards could be a huge issue.

      The extra kits are not quite at 43 because in addition to "$1" backers there "No reward" backers. I believe I'm up to 8 extra unexpected kits at this point.

    43. Missing avatar

      Dominic Wild on May 30, 2012

      I saw one place and I was about to take it but it disappeared. I waited for another one, just in case and I was able to get one maybe 20 minutes later. There is 86 backers but only 43 on 1$ and more(86-43=43....) ... If you have too much command, I will cancel mine with no problem. I will come back maybe 5 hours before the end and I will cancel it if you ask me.

    44. Josh Gribbon on May 30, 2012

      Saw a kit open up and i got it, Ive been looking at the printrbot for a while now but at $550 it was a little high for me as a first printer! Looking forward to it! Also how will we be contacted?

    45. PaulMakesThings on May 29, 2012

      Well, I'm glad you're doing extra kits, I wouldn't want to push out a backer. I didn't know it was doing that, I just saw that one was available since I'd been checking so I grabbed it.

    46. Billy Zelsnack 2-time creator on May 28, 2012

      Hi Paul.
      Great timing. I have had a few people back out, but in your case you were able to get in because of a quirk in the Kickstarter pledge system. From what I heard, when backers update their pledge to including shipping cost it will automatically set their reward to "No reward" without informing them about the change. This means there is a short window for someone else to grab their spot. Because of this Kickstarter quirk 5 people in total have grabbed a spot and now I'm doing 30 kits instead of the intended 25.

    47. PaulMakesThings on May 28, 2012

      Just saw one open up and jumped on it. How did that happen? Did someone cancel a pledge? Anyway, I've just replied to the greeting message, I'm happy to be backing this project.

    48. Mark Nowotarski on May 28, 2012

      I threw a buck in to say congratulations on the best Kickstarter product development strategy I've seen so far. A limited run of BETA machines going to enthusiasts is genius. Too often I've seen projects let their funding go through the roof only to fall on their face when it comes time to deliver. Well done.
