    I won't be back in the office til monday, but I can probably print 3 more out to send your way. My small printer is all I have for dimensionally accurate prints at the moment. Depending on infill % it can take from 4-7 hours to print one.

    Speaking of infill %, I am going to start printing my parts tomorrow for the delta-six build. What would be a good % to print the parts at is 20% infill enough or should I go much higher? I am using abs if it makes a difference and print best at 0.2 layer height.. Can use pla to, but would have to order more first...
    Thanks.

    I printed some at 60% and once all bolts are tightened down the printed part is still the major weak spot. If your printer isn't nearly as large as mine, you could be fine with less.

    I have 6 and I am in Austin as well. Just let me know if you want them and we can meet somewhere.

    2 Vertex's Down 4 to go. Also got 1 Idler Cap down as well. All printed at 50% infill o.2 Layer height. It takes me about 4 & 1/2hr to print each vertex.
    They each had a small bit of lift ( peeling from bed ) at the most outer tips. The first vertex has the most and was printed just on a heated bed with painters tape and a 5mm brim. The 2nd has a much smaller amount and was printed on the glass bed on top a small amount of abs slurry again with a 5mm brim. It is still noticeable when placed on a flat surface but not near as bad as the other.. I am hoping they are still usable as it does not appear to effect hole placement. We shall see.

    Any one have a idea when the 1500mm black 20x40 will be back in stock all the distributors out of stock as well at the moment. Hoping to order on payday ( or when they are back in stock)

    Parts Pic.

    Hamlin, I posted a reply that I have 6 ones here in Austin for free. If you do not want them, anyone else need 6 black vertexes?

    Here are some of my latest pictures. I have printed my modified vertexes and heated bed mounts. I have fitted one of the hall-effect endstops with the magnet in a modified carriage.

    Anyone have a carriage for the delta6 that supports magnetic mounts (instead of the traxxas joints) and attaches to the vslot plate? If so, could you please share the scad / stl file?

    Many thanks!

    Here are the bigger vertices I made with openscad, they're nothing special, but have a lot more rigidity than the originals for tall printers.

    It seems that I can't attach files in the thread.

    Thank you! That worked out great, I was able to import the code into openscad and create my own files with out a problem.

    Hi everyone! I've been wanting to build a Delta Printer for months now but I don’t have access to a 3D printer. Would anyone here be willing to print and sell me (6) Vertexes so I can get started? I know I'm asking a lot but I promise to pay it forward in the future 'cuz that’s the kind of guy I am. :thumbsup: I'm in North East Ohio if anyone can hook me up I would greatly appreciate it.
    Love the build Sage! Thanks for sharing!

    I went to 3D www.3dhubs.com/hubs and found a local guy to print my stuff. Also try www.makexyz.com
    Pretty cool, just upload the .stl's and it will give you quotes.

    Make sure you check their ratings and prices. I printed all of the parts and updates for a Luutr3k and I haven't seen any others that use more printed parts. Yours should be pretty inexpensive.

    I uploaded the vertex_20x40.stl to http://www.makexyz.com/ and it came back with a quote of $35.08 each at 87.5 cm³ - 1.97 in x 1.97 in x 1.97 in. for "Strong, LEGO-like plastic" which I assume means ABS. That comes out to $0.40/cm³. Is that a little steep? I was expecting closer to $0.25/cm³ or around $22.00 each plus shipping. While we are on the subject, what material are you guys using?

    Mine are ABS and I paid .25. Keep looking at the sites. Usually 1 $ dign translates to around .25 I have found

    Where did you find that .stl? I must have missed it. I wanted to see what I could get them made around here.

    I am using ABS as well with 50% infill, I printed my own so I am afraid I can not offer a good price point example. I need to spend a chunk of time and dial in my printer. My print quality is still suffering a bit ( see above warping.) otherwise I would be happy to print some for folks, it is a great design! Maybe once I start getting constant un-warped parts.

    I also considered doing the parts in pla ( other then parts near hot end ) but I don't have any to test with. Nor do I know if that would be a good idea ( have always used abs )

    Its in the Delta-six.zip file under the files tab...here ya go Digger : http://www.openbuilds.com/builds/delta-six.476/#openbuilds_files
    When you unzip it you will find the .stl in a folder named "Release"

    I'm going to assume you are using a heated build platform with the ABS. Correct?
    I've seen people virtually eliminate warping/lifting from the bed by printing over blue painters tape, and applying a bead of Cyanoacrylate Adhesive aka "Super Glue" around the first layer. This temporarily bonds the part to the bed for the duration of the print. Check out Werner Berry's "BerryBot3D" videos on youtube. He's got a beautifully designed, scratch built, Delta Printer.
    Here ya go Kyo:


    Hope this helps!

    Hey man, love your build, right now i've a Prusa i3 Boxed that i've completely build and perfected myself, i'm quite satisfied with it but i've decided it's time to do something new with v-slot and your build struck me immediately.

    I'm a bit of a perfectionist (and not so expert about delta printer) so i've got a couple of question for you:
    -i guess the distance between the rod ends at the effector and at the carriage must (or better be) the same and that's why your effector is bigger then the ones you see normally (and with normally i mean on thingiverse), i'm having trouble finding an extruder mount that is compatible with your effector, could you post or link the parts that you are using? and about the effector, i could use any effector if the distance between the rod ends is correct right?(i'm thinking about openscad effector that i could adapt)
    -secondly, the lenght of the rods is quite important i guess, longer rods give you more print area but obviusly take away print height, am i correct?
    so what lenght you recommend/use for your build?

    Sorry to bother you with such basic questions, again, love your design and i'll probably build something and share it with you in the near future!

    I started this build last weekend. 4 vertex done, two left to do! By the way, in the part list, you need 4 2040x1000 v-slots, not 3. 30mm M5 are really too short and there is a lot of thing missing in the parts list. But great build! Once my vertexes will be finished, I will offer to print some for those who don't have access to a 3D printer.

    Awesome dddman! That's what I like to see. Builders offering to help their fellow builders. Are you using ABS? I need six vertexes. Preferably Black ABS. Let me know the pricing when you get around to it.

    @Nugz I use PLA, ABS is simply a PITA to print with :p For you guys, I think it would be around 20$ CAD a piece :) This is what it will look like:

    My parts are all printed, I have some warping on the "legs" of the vertexes, but it doesn't affect the build at all. I made some modifications to the file to be able to put in the M3 and M5 screws without drilling. If you decide to buy some from me, be aware that at this friendly price I don't cut the 5mm brim, so you'll have to take 5-10 minutes to play with your X-Acto (Yeah playing with a knife!) So if anyone interested, just send me a private message with the color you want (expect maybe 3-4 more days if I don't have the color in stock)

    Hey dddman, I feel like I owe you a reply. I'm going to hold out for someone who can print my vertexes in ABS. I have a custom designed heated bed in mind for my Delta build and I'm concerned that the PLA might not hold up well with the temperatures involved. I do appreciate the offer and would like to thank you for being so generous to the community.
