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!

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!
