Great video, you seem to have really nailed the movements!

thanks, it was a challenge at first trying to figure out how to program my 6-channel Radiolink pistol radio to do the track movement, also, it would have been better if there are 2 more channels available but i just have to make use of the 2 channel with toggle switches, and 1 with a dial that would work as a toggle switch too. channel 4 is unusable since it is normally on and only push button to turn off so not for the up-down movement of a cylinder... i may have to get a new radio that is at least 10 channels for my upcoming projects.

Not sure how you feel about radios but a flysky i6x is 10 channels... I like them for my D5 and delta loader because I can mix the tracks onto one stick.. The i6s is also 10 channels I like it for my excavator and other track driven cranes or drag lines because it has 2 dials on each corner of the radio to use for the tracks leaving the sticks free for boom up/down, cable in/out,slew,etc..

I dont have preference on radios, i have a flysky GT3B 3-channel radio for my other crawlers and i like it...if its cheap and works just fine, im on it lol... i never thought that i6X has 10 channels which will be great for my projects... also, if the receivers are not so expensive, then im going for it. thanks for the heads up

the radios are about $60 on Amazon,

the receivers 6 channel is $18
https://www.amazon.com/dp/B07Z9YNP7S...v_ov_lig_dp_it
and the 10 channel is $21
https://www.amazon.com/dp/B0B74H861D...dDbGljaz10cnVl

and this 6 channel is$18

If you look around even on amazon you might find them a few dollars cheaper

Mock up of the cab interior...

[ddmckee54]

At first glance I thought those were resin printed parts, and thought that you'd gotten a resin printer. Then I zoomed in on them and saw the layer lines from a filament printer. That's some damned fine work. I can see that the cab is made of of a LOT of separate pieces. What's your nozzle size and layer thickness? I've printed pieces for models before, but nothing that finicky.

How many hours did it take you to model the cab parts? I may have asked this before, but what software do you use?

Again, NICE WORK!!

Thanks, i think i used a mix of 0.16 and 0.20 layers... nozzle is still stock.... 0.16 for the really tiny pieces and 0.20 for the rest...took me a while to get this done as I have been busy riding my MTB during the summer... but if I had to do it full time, maybe 10-12 hrs more or less... i dont have any other references except those i can find online and its a mix of different cabs.... its all guestimate i would say...I only use autocad...and cura for slicing...

[jerry56]

Holy Cow that level of detail just boggles my mind....

Inside of the engine bay where the cylinder actuators, smoke machine and receiver are placed...

Testing the smoke machine.... water based... cold smoke

You say your nozzle is still stock, is that a 0.4mm nozzle or something smaller?

yup, still 0.4 nozzle...

I can see I'm going to have to crack the whip on my printers and not accept any more shoddy work from them.

I normally print at a 0.25mm layer height but I have printed a couple of prints at 0.1mm, the amount of detail that an FDM printer is capable of at that layer height is amazing.

I usually print at 50-60mm/s, what do you set your print speed to for these detail parts?

i never messed up with a lot of the stock settings, i believe it is running at 50mm/sec, i mostly print at 0.20 layers, 0.16 if i want better details and smaller parts and 0.28 for rough parts (internal) 100% infill.... anyway, im thinking of putting a reversing sound for this dozer but cant seem to find any reference, i have seen a couple of videos of some guy converting a bruder wheel loader to RC and he got a reversing sound installed on it, but no info whatsoever... if you happen to know something pls let me know. thanks

[jerry56]

Thanks for the hints on the printer settings....most of what I print are just brackets and stuff, but good to know stuff right there...
I'd also like to fine a back-up horn.... just the horn I don't need the engine sounds...

Have you checked the Arduino forums? Odds are good that somebody has already posted a How-to on how to do it.

I did, but unfortunately, i got confused even more, i guess electronics is not really my thing lol.... but i was able to do it, using a servo plugged in to the throttle channel with a wye harness, then a cam disc pushing a limit switch to turn on and off a piezo intermittent alarm powered thru a spare channel of the receiver.
