Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

Thank you. This project had to be put on hold for a while. Hopefully I will be able to pick back up on it in a few months.

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

I'm using ABS for most everything. It is easy to work with and can be strengthened and bonded with acetone. I am tempted to try some carbon fiber impregnated filament for the lift arms and front...

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

The supports, other than the triangular pieces at the end of the track pads, are generated by my 3D Printing software. The way support structures typically work, is that the printer will skip a layer...

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

No problem, Trackerman. It took me a fair amount of trial and error to find a way of printing the tracks that made me happy. I ended up designing some "ears" on the outside that provided a footing...

Re: Smoke systems?

The smoke systems that the drift guys use are essentially e-cigs. You just need a coil, wick, reservoir, and a fan to move air. The most "smoke" is made using vegetable glycerin. It can be had...

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

Managed to get a few more parts printed and some hardware ordered. I now have over half the tracks printed (38 per side) and the hardware to link them together.

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

I made some progress over the holiday weekend and actually started printing a few parts. Since 76 are going to be required, I started off with some track link/pads.

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

Spent a little more time modeling in some details. Also, I started working on some motor mounts. I plan to use Pololu 25D motors for motivation so I have been designing the mounting system based...

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

Thank you. I am planning on printing as much as possible. I am trying to design extra strength into the load bearing areas of the chassis and moving components. Hopefully it works out well, but there...

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

Lots of hours. I should keep track, but I'm not sure I actually want to know. :) Good CAD software seems to always be expensive unless you have an older copy or something. I use Solidworks for my...

I started adding some detail to the chassis tub up front and along the sides.

Re: 90 ton 1/14 metal excavator scratch build w/embedded PC

Stein,

Thanks for the detailed reply. That is a good printer that you have. My first printer was actually the FlashForge Creator Pro, that I purchased to use at the company that I worked for. It...

Re: 90 ton 1/14 metal excavator scratch build w/embedded PC

Your prints are coming out really nice. What 3D printer do you use? Are you able to change your nozzle size for printing some finer details?

Re: 90 ton 1/14 metal excavator scratch build w/embedded PC

Great idea using the smoke machine. The RC drift guys have been trying to use smoke generators for a while now with mixed results. I think it should work well for your application though since it...

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

Thank you.



Yes it has been, and will continue to be. I think that putting in the time up front to develop a good CAD model will pay off when the build actually starts.



Thank you. Lots...

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control

Was able to spend a little more time doing CAD this week. I was able to rough in the engine cover, rear grille, and the basic cab structure. The overall look is starting to shape up.

3D Printed CAT 963K Track Loader w/Raspberry Pi Control

This is my first construction equipment build. It is inspired by JDH429's awesome D10 3D printed build, SteinHDan's Raspberry Pi controlled projects, and my interest in track loaders in general.

I...

Re: 3D Printed D10T Build

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