PG52 Posted October 28, 2013 Posted October 28, 2013 Thanks all ! This render is very nice, doesn't matter for the arms, complex geometries are always very hard to obtain on LDD, I can't imagine on LDraw... I've finished the V5-2, it is coming soon (end of the week or maybe tomorrow if I find time), it works well but the design isn't as good as the fourth's one. Quote

I've finished the V5-2, it is coming soon (end of the week or maybe tomorrow if I find time), it works well but the design isn't as good as the fourth's one. Well, I used SR3D Builder and it is very easy, even with complex geometries. Because it has the "Connection Solver". Just select the 2 parts you need to connect (and if needed select the preferred rotation points) and it automaticly connects the parts. But sadly, it didn't worked for the ball joints, but I'm sure it will be fixed in a future release (it's still a beta software). Quote
Philo Posted October 29, 2013 Posted October 29, 2013 Just for the challenge, I made a version with connected arms. Get it here! The trick was to attach the two arms together first, with only one ball joint connected. Then adjust progressively the two arms angle and rotate the ball joint till it fits properly the other ball joint (using hinge mode). But definitely the ball joint is always a nightmare to adjust in SR3D... Quote

Nice idea, I tried some scaffolding too, but didn't came up with that idea I hope you're fine with me updating the download-link and image? Of course I'll credit you too Quote

Blakbird Posted October 29, 2013 Author Posted October 29, 2013 I like the collaborative effort here. I have taken the SR3D file and created an MPD for MLCAD. I've broken it into a few logical submodels and added some rudimentary building steps. Anyone want to take it from here and add more building steps? I've also completed a Brickstore parts list file if anyone is interested. 764 parts with an average value of about $108 USD. That could be reduced by using an M motor instead of an L. Quote
Philo Posted October 30, 2013 Posted October 30, 2013 Anyone want to take it from here and add more building steps? Can you post your MPD? Quote

WOW thanks blakbird. Do you think it would be possible to build a much bigger one say one that produced drawings at A4 or A3 size? Perhaps removing the gearboxes and just run with a combo that works nice? Quote
legomuppet9 Posted October 31, 2013 Posted October 31, 2013 Amazing job, I'm going to have to see if I can build this Quote
Blakbird Posted October 31, 2013 Author Posted October 31, 2013 Can you post your MPD? I've posted it on my Bricksafe page. Do you think it would be possible to build a much bigger one say one that produced drawings at A4 or A3 size? Perhaps removing the gearboxes and just run with a combo that works nice? I'm sure it would be possible, but I think the flexibility of ABS would start to become a problem and this may interfere with smooth traces. Quote
PG52 Posted October 31, 2013 Posted October 31, 2013 The 5th works in size A5 instead of A6. A friend, Cedric has made one which makes drawings in A4 but it is much more unstable... http://forum.brictechnic.fr/viewtopic.php?f=114&t=5335#p61460 Quote
Alasdair Ryan Posted October 31, 2013 Posted October 31, 2013 (edited) Blakbird are you missing a part to link the selector to change the gears or speed? (below the 42 tooth gears). Edit Yes you are, there should be a thin liftarm with axle hole and peg on each side. Edited October 31, 2013 by Alasdair Ryan Quote

Edit Yes you are, there should be a thin liftarm with axle hole and peg on each side. I don't see anything missing, can you send a picture? Are you getting any errors when you open the file? Maybe you don't have the part in your library. Quote
Philo Posted October 31, 2013 Posted October 31, 2013 I've posted it on my Bricksafe page. I have started to step the base. Fortunately parts remained properly grouped, so it should be (relatively!!!) easy... Quote
Alasdair Ryan Posted October 31, 2013 Posted October 31, 2013 Picture: I am also missing the steering arms at the top as well. Quote
Blakbird Posted October 31, 2013 Author Posted October 31, 2013 Picture: I am also missing the steering arms at the top as well. Those parts are not missing in my model. I can see them fine. You must not have those parts in your library. The part is 33299a.dat. It is a variant of 33299 (I don't know the difference). Quote
Alasdair Ryan Posted October 31, 2013 Posted October 31, 2013 (edited) Yeb there is the problem in my library. I will step the arm and maybe something else,I will see how I get on. Edited October 31, 2013 by Alasdair Ryan Quote
Alasdair Ryan Posted November 1, 2013 Posted November 1, 2013 (edited) The arm is done,to download the complete MPD file here. Here is a "busy" screen shot,I have not changed the quality of the pictures. Who ever compiles the parts can do this,to make it the same through out. Updated view in cad file for step4 p5. Edited November 1, 2013 by Alasdair Ryan Quote
Blakbird Posted November 1, 2013 Author Posted November 1, 2013 Excellent. Update this thread with progress so we do not duplicate effort on the same sub models. Quote
Philo Posted November 1, 2013 Posted November 1, 2013 (I don't know the difference).It's just a different model of axlehole... only for the nitpicker! Quote
Philo Posted November 1, 2013 Posted November 1, 2013 Here is the front gearbox module, which can be built separately from the base. There are steps in it, but things need to be reordered to make it buildable. I let this for the moment to another guy... Going on with the base! Quote
Alasdair Ryan Posted November 1, 2013 Posted November 1, 2013 (edited) I will do the plotter table next,should be done.....soon. Edited November 1, 2013 by Alasdair Ryan Quote
legomuppet9 Posted November 1, 2013 Posted November 1, 2013 And then would it be possible to upload this to rebrickable so people can check if they have the parts? with PG-52's permission of course Quote
Philo Posted November 1, 2013 Posted November 1, 2013 Here is base file, in current stepping state. I am somewhat stuck, I can't find a good building sequence for the last element I stepped (see comment in file for location). Any Idea? Quote
PG52 Posted November 1, 2013 Posted November 1, 2013 Of course you have permission to put it on rebrickable Quote
