    Dollo 3D: Self replicating 3D printer

    it doesn't work like that. I don't do bearings because its not needed. and you can't get rid of the other y motor because it flexes way to much since it has no metal parts in the joint.

    yeah, I know I had not yet made the new z corners, I have been using metal rods to get rid of variables while its still all being tested. The issues with the parts fitting isn't necessarily the models issues, what I have seen a lot of is different slicers, or different machines, tip sizes, all those kinds of things can change how well parts fit together, you will see in a lot of the .scad file I have a thing asking for tip size, that is there so that I can compensate for the top diameter and make parts that fit better.yeah I do need to make fix that include warning. As for a frame, you can use the long slots to make short "long ties" and slide them into the slots with a small hole for a magnet and then just press fit magnets into it and do the same on some plexiglass to make &...see more »yeah, I know I had not yet made the new z corners, I have been using metal rods to get rid of variables while its still all being tested.

    you for sure won't need glue, the frame is crazy strong when you have all 8 (4 corners and 4 long ties) in the joints.I can get the x and y to move at about .25mm accuracy with no lashing (as it has no belts)I agree with you on the Z axis, the idea is fun and it was just to say yes you can do it, but its not supper accurate as it tends to rotate about 1 degree between layers I have been trying to work on it but eh, the only thing its good for it being able to scale with out getting new metal parts. If the parts were injection molded it would work file, but they aren't sooo..... yeah.it says that include isn't being pulled in but really it is, it gives a warning but it does still work.I have tested all of the include files, they are used everywhere in the printer files and I rendered all...see more »you for sure won't need glue, the frame is crazy strong when you have all 8 (4 corners and 4 long ties) in the joints.I can get the x and y to move at about .25mm accuracy with no lashing (as it has no belts)I agree with you on the Z axis, the idea is fun and it was just to say yes you can do it, but its not supper accurate as it tends to rotate about 1 degree between layers I have been trying to work on it but eh, the only thing its good for it being able to scale with out getting new metal parts.

    what parts were mismatches in the git repo? (might just need to re render and export the .stl's)

    thank you for doing my job and replying to the questions :) I must have missed this notification a while back

    yes the long ties is the current version that I am working on, I don't have the twisted corners in there yet, because it was just a lot of variables to calculate in for print quality. I have just been using metal rods (I know its not with the methodology of the project) so yes its still a work in project, if you want you can model up the z parts in openscad, just take the old .scad file and change out the difference with the new long ties (look at the rails for inspiration on how to pull this off)I am working on the final details for the official dollo kickstarter, so if you want to wait a little bit you could get a kit of printed parts, and required hardware from there, and you will know that its all of the parts and the right versions.
