Re: 3D Printed D10T Build
 

Jason, I've haven't had experience with the sabertooth motor controllers yet but have a conversion on the books for one, why did you use 2? I thought that the 2x12 operated 2 motors? Sorry if I missed this somewhere.

Re: 3D Printed D10T Build
 

Thanks Ed

Thank you!

Thank you!

I used the second controller to operate the 12 volt linear actuators on the blade. These controllers are great, and will def use them again for my next project.

Now it makes sense, driving the actuators separately to get your blade tilt;):cool:

Re: 3D Printed D10T Build
 

You figured out my secret!lol Doing it this way works awesome. Add another actuator to the C frame and you get the tip function. It all works very well and is quite easy so long as you have everything pivot and only anchor the blade on one side. I'm not sure if Jason is running his this way or not though? Are you Jason?

Re: 3D Printed D10T Build
 

Thanks Bo! The printer did most of the work :)

Yes, Im just using the actuators for blade up n down, and have both actuators tied together so the blade does not tilt left or right yet. I wanted to prove everything else out before getting tricky, but after running the dozer that function would be useful so will be working on that in the future.

Reg, yes your secret is out as i am doing exactly that. And yes the blade uses a draglink which is mounted on one side of the front of the dozer chassis. I should have moved that point as far to the edge of the chassis as the radius of that drag link would be larger and on full lift and drop of the blade, the blade shifts in towards the tracks as it follows the radius of the drag link. No rubbing, but ive made a note about that for next time.

Re: 3D Printed D10T Build
 

Haha, not much of a secret!:rolleyes: My first try at making the blade tilt didn't go great because I was using two actuators to "tip" the blade and that caused binding when "tilting". When I built the second conversion I didn't use any for tip but had learned from the first that one side of the blade must anchored to the C frame and the other side must "float". If both sides are held tight it will twist the $h!t out of everything and you won't get much tilt on the blade. I also switched from rubber bushings to spherical bushings where the C frame mounts to the track frames. This made a big difference as well as there is no resistance at all against twist. I went back and redid my own conversion and the blade tilt and tip works great now. Lot's of trial and error but we eventually get this stuff working sweet!:bounce::bounce:

Re: 3D Printed D10T Build
 

Wow, good info there. Thanks for sharing that. Yes, Test n tune is the name of the game here. Thanks for following the build and your help Reg.

Re: 3D Printed D10T Build
 

Haha, yes lots of trial and mostly error. I usually get things figured out but sometimes the learning curve is steep. Happy to help any way I can....

Re: 3D Printed D10T Build
 

Beautiful finished build there sir!

Re: 3D Printed D10T Build
 

Can you add sand in the honeycomb for weight?

Re: 3D Printed D10T Build
 

Thank you

Sure, I dont see why not.

Dozer featured in 3DPrint.com article.

Re: 3D Printed D10T Build
 

Would it be more expensive to print something like this in color? It would hide wear and tear better wouldn't it?

This project is fantastic btw, I hope to see more builds from you done like this. The article mentions casting wheels in a 3d printed mold, sounds awesome.

Re: 3D Printed D10T Build
 

Thank you, believe me if they had a cat yellow filament I would be all over that. My next project is going to be a Euclid dump truck. They were like a lime/neon green and I happened to order filament close to that, so there will be less painting thankfully. On the other hand I did go with the grey so the wear was more noticeable on the dozer tracks and uc parts, I like it kinda.

Re: 3D Printed D10T Build
 

Very interesting build (and technic with printer). Would love to learn more about using printing. A lot of details could be made this way!
Can't wait to see your next model, especially how to make those tires!

Re: 3D Printed D10T Build
 

Your killing me Jason!:eek:

What a sweet looking combo:cool: I'm in love! :lol:

Re: 3D Printed D10T Build
 

NICE! Are these the same scale? Can't wait to see the 657 sitting there with them!

Re: 3D Printed D10T Build
 

Haha, Thanks Mario

Yes they are both 1:14 scale, roughly :). The 657 will be a giant. In this scale should be close to 4' long if i remember right. The tires are 7" tall. Still a bit of a ways away from seeing that picture. Thanks for the comments.

Re: 3D Printed D10T Build
 

Very nice, well done on both machines!

Re: 3D Printed D10T Build
 

Love you work JDH429 :)

What clearance did you use between your different parts ?

Re: 3D Printed D10T Build
 

Jason,
How is the printed running gear going for wear? Really interested in your build.

Cheers

Paul

Re: 3D Printed D10T Build
 

Very nice work, very interested in those printers.

Re: 3D Printed D10T Build
 

Did you quit building?

Re: 3D Printed D10T Build
 

He'll be back. He's just had a busy summer/fall.

Re: 3D Printed D10T Build
 

I've really enjoyed this thread. It inspired me to start my own 3D printed track loader project.

Re: 3D Printed D10T Build
 

wow!!!!!

Re: 3D Printed D10T Build
 

This is incredible ! I want one! Outstanding work !!

Re: 3D Printed D10T Build
 

JDH429 you did a h3ll of a job on the build, looks bloody great :cool:
Have you ever got a chance to weigh the dozer ?

Re: 3D Printed D10T Build
 

I LOVE IT! I wish I had the ability to do things like that. I DON'T know much about computers, so CAD, & technical stuff like that is outta the equation for me.

Re: 3D Printed D10T Build
 

Thank you!

I haven't weighted it but It feels like 12 lbs maybe 15..?

It's never too late to play around with a free cad program and then maybe get a cheap printer to start out with. StArt with some simple models and work your way up.

Re: 3D Printed D10T Build
 

I DIDN'T know htere were free programs! I thought all that powerful software was expensive. Do you have a link to such program that you'd recommend?

Re: 3D Printed D10T Build
 

Autodesk 123D and Tinkercad come to mind and Fusion360, although I'm not sure if that one is free or not. There are some others I'm sure. Plenty of Autodesk tutorials on YouTube to get you started too.

Re: 3D Printed D10T Build
 

Thank-you sir! I'll look into downloading one, or more of those, when my brother gets here to visit. He's the one that knows how to initially get stuff like that into my computer.

Re: 3D Printed D10T Build
 

No problem, have fun!

Re: 3D Printed D10T Build
 

Jason,

Are the track pads on the dozer printed? Is that a difficult print? It looks like there would be an overhang no matter which orientation it was printed?

I'm thinking about getting a printer or having a friend print track pads for my little Oliver Dozer.

Thanks for the great build thread, great work!

Jim

Re: 3D Printed D10T Build
 

Jim, yes I printed them and the way I avoided any support was printing them at a 45 degree angle, and a fine resolution. They came out great. I think I may have a pic showing the part orientation. If I'm going to make more in the future, I would like to try printing out of nylon, not that mine are worn but I really avoid driving it on anything but dirt if you know what I mean.

Heres how they printed... And a little trick i use when the part doesnt have alot of area to stick to the build plate in the printer like the chain here, is to design a small pad onto the part that gets printed like a foot, and later is easily broken off after the part is done. I loaded the build area up with as many tracks as i could fit. Hope this helps.
