weavil Posted January 27, 2014 Posted January 27, 2014 no one knows how this years flagship looks, maybe it looks better than mine Only if it has 6 motors and every part on my wish list!!! Quote
Zerobricks Posted January 27, 2014 Posted January 27, 2014 Looks really great and massive, Effe. Just one complaint, the light gray used in LDD is too light. Quote
efferman Posted January 27, 2014 Author Posted January 27, 2014 is the medium grey the grey from the frames? weavil, why six motors? Quote
weavil Posted January 27, 2014 Posted January 27, 2014 I could use about 2M, 2L, and 2XL. That way I don't use 4 driving rings and still limited functions. I only got 4M motors. Quote
Azzepa Posted January 27, 2014 Posted January 27, 2014 If anyone can take on the project of converting this from LDD to LDraw, I'll make some renders of it. It is a great model. Oooh. Might take you up on that one. Wanted some LDraw practise. Seems like the perfect thing, lovely model! Quote
Azzepa Posted January 28, 2014 Posted January 28, 2014 Eep, sorry for the double post but sat down for a bit to do some MLCad. Didn't convert directly from LDD as wanted the better practise of knowing where parts are and doing things manually. Half hoursish work: Before I continue too much further, would anyone want this in a stepped format for instructions? Might have a stab at making those if there's any interest and Efferman doesn't mind? Quote
efferman Posted January 28, 2014 Author Posted January 28, 2014 U need a step by step for the axle or for the whole loader? Quote
Azzepa Posted January 28, 2014 Posted January 28, 2014 U need a step by step for the axle or for the whole loader? Sorry, don't know if that was very clear or not (or I am getting the wrong end of the stick as to what you mean), referring to the "steps" in LDraw, so LPub can generate the instructions, was wondering whether anyone would be wanting a pdf version of instructions from LPub rather than following LDDs frankly, rubbish instructions. Quote
efferman Posted January 28, 2014 Author Posted January 28, 2014 Aah there was my english not good enough. Feel free to make full instructions. Quote
Zerobricks Posted January 29, 2014 Posted January 29, 2014 I wonder if the dozer's rear axle pivots like the real thing? Fenders do look higher on the rear. Quote
efferman Posted January 29, 2014 Author Posted January 29, 2014 yes, my loader has a pendular rear axle, not sure if the 42030 has one. And yes the fenders on the rear are higher ti give the axle enough movement. Quote
efferman Posted February 8, 2014 Author Posted February 8, 2014 ok, wat is a schürfdings? a scraper in english source and if i finalize it it will be huge the tires 100_0571 von efferman auf Flickr the plan is to use two XL motors, one per axle and articulated steering with big Linear actuators Quote
Rishab N Posted February 8, 2014 Posted February 8, 2014 That's gonna be enormous! Looking forward to more progress Quote
efferman Posted February 8, 2014 Author Posted February 8, 2014 indeed and now i see how complex it will be. the actual standing at the moment i see following functions: lift and lowering the craping bucket lift and lowering the front shield of the bucket the mechanism which pushes the payload out of the bucket steering driving and because there is one function of a receiver not used maybe a elevator mechanism Quote
Alasdair Ryan Posted February 8, 2014 Posted February 8, 2014 (edited) lift and lowering the craping bucket I think a scraper will make a interesting build,I look forward to more. Edited February 8, 2014 by Alasdair Ryan Quote
efferman Posted February 10, 2014 Author Posted February 10, 2014 oh my god, what an epic typo btt, because i want do some functions pneumatic i have need a remote controlled valve and this is my solution Quote
Junpei Posted February 10, 2014 Posted February 10, 2014 That servo valve is genius, I love the use of the 3L pin with hole to handle the angle caused by the pivots of the switch and the servo being out of line. That thing is gonna be huge! TLH Quote
unimog123 Posted February 10, 2014 Posted February 10, 2014 That's a great solution! Although doesn't this mean you'll need multiple servos, which aren't cheap. Quote
efferman Posted February 10, 2014 Author Posted February 10, 2014 thanks guys, servos are not my problems, more the small pneumatic pumps. one of my 6Lpumps has a leak so i can not make a symetric pump setup without seeking in a huge box of unsorted parts Quote
Hrafn Posted February 10, 2014 Posted February 10, 2014 thanks guys, servos are not my problems, more the small pneumatic pumps. one of my 6Lpumps has a leak so i can not make a symetric pump setup without seeking in a huge box of unsorted parts A huge box of unsorted parts is a problem I'd love to have! The servo valve is quite elegant. It will give not-quite-proportional control, since the axes of rotation for the servo and the valve are not in line, but that shouldn't be a real issue. In fact, I'm tempted to try adapting your idea to M-motor driven vehicle steering to give a variable steering ratio. Quote
efferman Posted February 11, 2014 Author Posted February 11, 2014 this evening we had in our chat a small discussion about this thing in lego and i was so crazy to think this would be possible with two motors, well, walking is something different Quote
D3K Posted February 11, 2014 Posted February 11, 2014 Well at least you got it to stand up like the real thing! Probably a good example of a thing that is way more complex than what you initially think! Your video made me laugh Quote
unimog123 Posted February 12, 2014 Posted February 12, 2014 That's pretty cool, maybe someday I'll take a shot at that. Quote
Brick_Sticker Posted February 12, 2014 Posted February 12, 2014 The servo on the valve is an excellent idea, can't wait to see your scraper completed. Brick_Sticker Quote
