    It’s good to see the mini working. I talked RustySpoon1121 into printing me a set of mini parts. Should have them in about a week or so. He said he was going to print a set for himself too. It won’t be long before there are several working minis.

      Cool! I’ve also printed a second mini-mendel set (almost, just missing some smaller bits). They’re for a conference ( http://www.shift.pt ). I will be sending the parts ahead of me and they will build it there and keep the (hopefully by then) working machine.

    Hey. Why don’t you print a third set and put put it up on ebay. Would be interesting to see how much it would go for. I know I would bid on it.

    Unless I can talk you into printing me a set? :)

    • Erik says:

      I’m both short of time and RepRap is costing me too much money, but I value my time more right now. It takes about 24 hours of printing and I need to get it to be more unattended first. I think the last kit took me 10 hours of human attention, so that’s way too much. But that included post-processing which the buyer can easily do as well (about 2 hour for the 100+ parts).

    Dear Erik,

    Im very interested about your bitsfrombytes firmware modification.

    Could you please elaborate a bit?

      It’s mostly in svn in the main reprap respository. I’ve got a version there that compiles for me in MPLAB 8.40. It worked for me on a v3.0 board (but it should also work on the newer, 3.1 board). No guarantees though!

      I’m extending their normal and development version to allow some interesting features. I don’t have endstops, so I changed it so that you can push a button to skip homing and home it manually. I’m also working on fixing bugs in multi-material support (that’s why there are two extruders in my mini-mendel!)

      If you get this to work, please help me document it as I haven’t had the time for it yet and my installation is not a clean one so it might work for me for reasons I can’t remember anymore!

      My language tool versions: pic32-as.exe v1.05, pic32-gcc.exe v1.05, pic32-ld.exe v1.05, pic32-ar.exe v1.05.

    I Really want to build a mini mendel but don’t have a 3d printer yet. Is there anybody out there that would print the part at a reasonable price for me? Email me at Robotguy@bellsouth.net

    In the Sprint of OPEN SOURCE I am also willing to make a deal. If somebody would print the parts for cost plus shipping I will print 2 copies to give to the next people that do the same I did. And they would be under the agreement to print 2 more copies and so on. I find the biggest problem with the mendel & Darwin is somebody to print the parts for a fair price.

      That’s what I thought the model should have been all along, and the mini mendel seems to be the most suitable design.

      Assuming I haven’t worked out another way to get mine before it becomes available (I’m also watching the ebay listings and fiddling with a cartesian bot from a kit), I would gladly buy a set on those terms.

      yes getting started is always the hard part.

    hey, I’m working on getting all my hardware together while my buddy prints my mini parts on his M4. I was hoping you could tell me how many of each bearing you’re using. between this post, the wiki parts list, the “pricing mendel mini” blog post, and the docs in the reprap svn, I’ve got 4 different values. I’m only trying to build the base printer, and not the spool holder underneath. thoughts?

  6. In December last year, I became the proud new owner of Leo (after Leonard Darwin), the son of Charly (Charles Darwin (my earlier machine)). It didn’t take 9 months to fully develop, but it seemed like a long time (the second and third sets of parts tooks
