    I'm planning also a Delta, which is similar to your design approach. I'll upload my plans in the next two weeks. Maybe we can learn from each other. It will be out of 21mm plywood and it will be cut with a cnc in the next month. I wish you good luck with your build!

    Whoa very nice @cameron ! Love the minimalist look to this design. The way this is designed looks like it could be built quickly and easily. Nice job

    Ok, so i've gone about this like it was a blog... that doesn't work so well... but here's a messy progress pic, nearly ready to get some parts checked, printed & ordered. I'm excited :)

    It is a bit different to get used to kinda a blog/forum in one. You can edit the build (only you have that access to your build) and you put the build pics and steps in the body section so that they show up under the main build tab. Source files like 3d models go in the files section and will show up in the files tab, etc..
    Keep up the good work @cameron !
    I am looking at this picture thinking that the arms are maybe too long? I found this that may help

    You may have already figured this, but if not hope this helps

    Also you may want to look at the Rostock project it has a lot of helpful documentation

    Yes those delta arms in your render are way to long. I am also working on a design for a delta, and after speaking with Johan the designer of the Rostock. they only need to be long enough to not hit 90 when going to the edges of the bed. He recommends 10-20degrees as the minimal angles from vertical and horizonatal.

    Thanks guys, so if we play around with say 85 degree's (base build dimension/sin(85) = rod length, which is a tinny bit bigger 100.4%). I did have some numbers somewhere but sorta lost them... but yeah, shortening those will give me far better control. I just got the print head support drawn and wanted to see the motion so did some approximations and dodgy's.

    What are peoples thoughts on the rigidity of this frame? might use the 1000mm sections rater than the 1500mm(shown above) sections to start with... the plastic are sls

    you could make it more rigid. When the arms are at the top or bottom they will be fine but when in the middle? It looks like there will be an inward force caused by the weight of the print head and this will pull the beams. The most deflection will occur in the center of the beams so just put a support there. I see that on the outside of the beams you have a v-slot rail which you can attach things to. Attach a brace there and leave enough clearance for the wheels and it should be extremely solid even if the print head is really heavy.

    Sono daccordo...con The Dude.... considera magari di ruotare di 90° i profili verticali così da avere l'asse di inerzia sulla sezione maggiore .
    Ammiro la tua idea.... se posso aiutare , dimmelo , perché anche io ho intenzione di fare una super big delta printer. ciao e complimenti.

    My first one is designed to be 1500 mm * 1000 mm
    Work area about 90% of this, plus X-axis is infinite :cool:

    per Public Do Omens WWWWW ...... Fai finta che le lettere siano i perimetri di appoggio sul piano....
    quindi con questo modo faresti un sistema a cella lineare che si può estendere anche molto, oppure mi sono sbagliato ????? Complimenti !!! sarebbe quello che vorrei fare io per costruire proto-automotive.....
    ti andrebbe di darmi una mano per favore ????
    saluti e rispetto !

    I would divide the task in hand. GeoMaxim.
    Work on one section then move on, just remember to make reference marks!
    In three dimensions.

    Is this an industrial project or private build?

    Can you please use Google translate on the Italian for all the English speakers.
    Easy for one to do translate once, then all users don't have to repeat the task many times, thanks, just an idea.

    Hello to you also :cool:

    for pubblic do omens
    The right question , you have a right ! I can not find work in Italy for 6 years ... ALWAYS respond that i'm " too qualified for the job "! So I started to create me my own reality , that in my heart I'm sure it will be successful ....
    I also hope by this to leave and raise my fate with all the effort that will be needed ! But are you sure that after everything that happened and we ( people who , according to their situations unmanageable , took their own life!)
    I will not sell or even sell me anything, anything I can create with others, or through recommendations ....
    Since I could barely survive (not live ), only I know what you mean fatigue patience and research.
    What's more, for no other reason , morally I owe it to those who are desperate for this whole Italian economic crisis unfortunately are killed, I think you can understand me .
    You are free to believe or not , to help me or not, I will anyway , I will be wrong but in the end I will study
    I reach my goal . I will prove to everyone that , if one wants to can make choices that do not necessarily lead
    dramatic conclusions . Moreover I would like to be sure that someone at the end of the work , I did not steal the idea and ask me the damage for some legal technicality ....
    Forgive me if I get involved in things my own , I hope that emerges from this that I write something more than myself.
    : Cool :
    Best regards ,
    with esteem and friendship

    In my area, there is a company that has this catalog of aluminum profiles and accessories ... I enclose ... I hope it is not too big file! I think it's interesting!
