V2.0 - 3D Printed RC Excavator DIY

[@maxsteamengine5986]

I'm a student at Western Sky Middle school and I help out in the STEM room after school. We have an ancient Maker bot replicator that was left out to dry after out last STEM teacher passed away. After I learned about his story, I started reaching out to 3D printer companies to hopefully get a new printer and start a club to teach anyone about 3D printing. We got no response from the companies we contacted and at this point I'm not sure what to do until I saw this video. My school would benefit very much from receiving even just one of the printers. I'm sure that our school and the students would benefit for years to come. Thank you, Max Murphy

[@ManIkWeet]

The fact that you're sharing the files for free is amazing

[@darkracer1252]

he isn't. he is not sharing the wiring diagram. or the circuitboard files. so the only way to make this work is the order the circuitboard from a kit. like he did with his other vehicles. this project isn't finished yet so the kit for it isn't on his site yet. he does however allow you to pay 10 dollars to get access to a tutorial that DOES have those files. so no. he's not sharing anything for free. it's just marketing to get people to pay on his website. don't worry though. i am devoted to building this project and doing so without paying this guy a single dime. so i'll just design my own circuitboard. and make those files available for free. if he was honest up front that this would cost money i would have had no problem with it. but he pretends that you can get the files for free and then excludes the most important part. that is why he isn't getting a dime.

[@TripHawkPilot]

@@darkracer1252 He is providing a service. You could pay him $10, get the files and info you need, and then move on... or better yet, support him! Cheapo

[@JeronimoStilton14]

@@darkracer1252the files for the model are free, and he does not lie or hide the fact that it isn’t entirely so, so you’re just spending your time to avoid this guy making money for his hard work. Nice job As far as I gleaned, though I haven’t finished the video yet, he doesn’t even do custom pcbs he just orders standard motor controllers and a micro controller. You should be able to (and can since you’re talking about doing so in your very comment) get by without the addition of those diagrams.

[@limbeboy7]

​@@JeronimoStilton14 that's half truth. He spends 15 mins explaining the inner workings. And they all require motor control. Just the 3d parts is almost useless as they have nothing to attach to

[@JeronimoStilton14]

@@limbeboy7 you can program each of those motors yourself, they’re not that complex

[@Twinsrule87]

I'm a volunteer STEM teacher at our local Christian school where I have a large focus on 3d printing, we are a small-town school with very little funding, so I donated my old Ender 3v2s(which we spend half the time tinkering on them) to the school. Would absolutely love one of these in the class! Thanks for the video. It's definitely on the next on the build list!

[@throwawaypt2throwawaypt2-xp8nx]

mark m?

[@GarrettBShaw]

Bamboo Labs is top tier for sponsoring those printers for the school. I've never used one or seen one in real life, but I've heard they're good, and after hearing that they did this sponsorship deal and makes me really interested in learning more about them!

[@dpmakestuff]

I thought I was a die hard Prusa user... Until I saw a Bamboo Labs printer in person. They're truly amazing.

[@conorstewart2214]

They are some of the best (if not the best) consumer printers on the market. When they released their first printers they were much better than most other printers and for the most part they just work with little need for tinkering, since then other printer manufacturers have been scrambling to try and compete. We still don’t have any great alternatives to Bambu lab products, especially the AMS systems which let you use multiple colours or materials within a print. A big part of why Bambu has been so successful is the price, they are reasonable for consumer printers. The only downside is the closed source nature and closed ecosystem, which a lot of people don’t like but so far Bambu lab have been decent with it and spare parts or upgrades are reasonably priced. Being closed source and a closed ecosystem is also a good thing, for the most part everything just works and you don’t have to (or can’t) tinker with it much. Bambu have also collaborated with other manufacturers already like E3D to produce higher flow hot ends and likely will collaborate more in the future.

[@gamernerd7139]

I have a Bambu Lab A1 with the AMS lite system. Absolute bang for the buck. I do a lot more printing than tinkering nowadays. In my country getting Bambu consumables like filament is expensive. But I have managed to configure it for other localy available filaments. And it works a charm! This and the A1 mini model could be the first printer for a beginer. I have an Anet ET4 pro, and the amount of tinkering I had to do inorder to get it tuned was humungus. Even an Ender 3 pro requires more tinkering before you can get quality prints.

[@DoctorKaw]

This channel is so underrated.Good job sir.

[@Cone_GamingYT]

Make a kit!!!!!

[@Splarkszter]

The design has a lot of compromises. I'd say polish it befor making a kit.

[@lizzard3699]

​@@Splarkszterdefinitely, but a kit would be great for those of us who don't own a 3d printer :]

[@DevinDiehl]

I really want to do it because I do have a three printer. But doesn’t work😓 … I very much do you like the kit idea

[@Cone_GamingYT]

Yeah… future me would be proud of what’s happening now.

[@ambikesandboards]

​@@DevinDiehl If it doesn't work it's usually due to the user configuration. Keep trying

[@841577]

Really fantastic! I’ve built two already. Working on the upgrades now. It’s lots of fun to have living room competitions with the family.

[@professorboots]

That’s so great to hear!

[@3DWolfEngineering]

I would say in case you would ever want to automate it, i would just manually add a external potentiometer - then it would still be strong and cheap while also being space efficient

[@professorboots]

That’s true, I might just have to do that

[@NitroTrinker]

I wouldn’t t use potentiometers. As you need multiple turns on some axis. You can also use some magnetic encoders. They are relatively small and also easy to get.

[@3DWolfEngineering]

@@NitroTrinker yeah magnetic encoders are more professional, thought about them too, just that they are less common and more expensive

[@NitroTrinker]

@@3DWolfEngineering Oh. Had the prices in mind for 500 pieces. If you only need a few they are pretty pricie. What does a small poti in this sice cost?

[@bmxscape]

@@NitroTrinker optical encoders can be very useful also as you can read anything that spins

[@dominikcz2266]

The whole build is awesome but I have to ask this question. WHO CUTS PEPPERS LIKE THAT?

[@markfrancis4341]

A Forklift would be awesome!

[@MIGHTYRAT]

That would be very cool

[@alexeivaningen]

orrrrr.. .a set of forks for the skid steer?

[@Official_Skypaper]

@@alexeivaningenhey if you have a skid steer there are already forks.

[@Rubi056]

Can't wait to get a slip ring installed and the push blade!! Great work

[@obadiahgrotts5084]

You should add your own potentiometers in the joints! This would give you the precision of the servo, with the power of the screw N20 motors. I've wanted to build a robot arm with this feature for some time now, but haven't found the time. Would be really cool in this excavator.

[@sethnowak9823]

I am so blown away by this man

[@Pablosaurus]

You can control all the motors you want through 4 wires if you put another micro-controller down there and use 2 for power and 2 for serial.

[@DaveEtchells]

Wow, this is _insane!_ Hats off to your CAD and design skills, this is such a cool project!

[@aaro_n]

As learned from my mini skiddi v2 I think I'll wait till v3 comes out, but this build is absolutely amazing!

[@oripaamoni]

Wow, I underestimated how much fun this thing would be to use! been loading up the dump truck with hot wheels haha. Thanks again for all the hard work on this, me and my 3 year old love it! Any reason I can just plug in a 3s battery to the PCB? the motor are all 12v and it looks like the step-down regulator can handle it too.

[@professorboots]

I’m glad you like it! The H-Bridges are only rated to 10v but that said they’re less than a dollar so might be worth a shot haha. Everything else should be able to withstand 12v just fine. The motors will burn out quicker overtime but that’s to be expected

[@blakemitchell6039]

I can't wait to build one of these with my nephew , it's awesome!! There's a new nonprofit makerspace in my area and I believe a bambu printer would serve many people very well in many ways.

[@OnlineObsessionista]

Looks awesome! I hope some day I'l try to order a custom PCB to try this out

[@Niklas_Richter]

cant you use the audio jack slip ring for the claw. its smaller than the one for the tracks and has enough pins

[@XxBoboSoloxX]

IBIB (It Begins In Brockport) is a makerspace near me run by my college professors that just celebrated their 1 year anniversary. They have a couple older printers we have been using to make some 3d printed sumo bots (as well as many other projects) and I'm sure they would be ecstatic to get a new one!

[@assamita81]

You can use the audio jack for the claw, instead of the slip ring

[@nicholasdelrossi3996]

Hey just a tip, I’m working with really small 3D printed gears right now (I’m a mechanical engineer) and they DO work, even on a bambu, you just need to play around with the profiles as well as the amount of teeth!

[@nicholasdelrossi3996]

Also if you need a donation place, my hometown is a poor high school and really need printers for their new engineering program!

[@tastiekakes1123]

Have you thought of trying a push/pull cable(bike cables) actuation for the tool ends and remote mounting the motors in the body? Then you will be able to power different types of tool heads with a slimmer profile

[@bmxscape]

then you can make the housing of the cables look like the hydraulic lines

[@milesisgoodatlife948]

Love your videos you do all the things I could dream of doing with 3D printers and Arduinos I have tried doing some projects like this but they all failed. Look forward to seeing all of the amazing things you make and inspiring people like me who love this kind of stuff!

[@jorgeestefania3184]

If you want to automate it, you could use magnets + hall effect sensors to determine the absolute position of each part, independent of motor rotation

[@Mitakskia]

Next week I will receive the final part of the puzzle - the screws, and finally can finish the v1 build. Good thing that i purchased all the components for 2 excavators so i can have spare for the accessories!

[@professorboots]

Oh you’ll be good to go then!

[@andfil22]

Hello, nice upgrade. Create a TPU parts at the end of your claw, just to add grip ;)

[@DSZI.ShyHunterBB]

Are there any plans for a hydraulic version? It would be much stronger that motors and more realistic.

[@06wattsie06]

This quality of content definitely deserves more subscribers! - Also, have you considered making a version that's inline with the Bambu Lab maker supply incentive program? I could definitely see this being a maker kit on their website and if you use solely parts available from Bambu you would also get a nice kick back from anyone buying parts through your makerworld upload :) - Great work!

[@articjackal]

Dozer for sure. Maybe a PLA track instead of TPU. So its actually linked together.

[@frostyMT8]

Now this is awesome brother!

[@professorboots]

Hey thanks man!

[@foxjet77]

Time for a semi to haul your heavy equipment. Great build!

[@SantaDragon]

Awesome printed toy project. Congrats!

[@thefreeheathenworkshop]

amazing work again, so if you were to make it fpv what camera would you use and where?

[@professorboots]

I’d pry do a very similiar setup to what I did the MiniSkidi a while back

[@thx9977]

Put a little camera on the esp32 and make it controllable via the internet! So people can share it with friends or just use it from another room via WiFi. Crawl space adventures would be a cool thing to do .. 😊

[@Evilslayer73]

This model is very cool and the upgrade too !excellent work young man!👍👍👍

[@MatthewSolsky]

Hey one more thing, have you thought about making the claw assembly as a posible quick swap like you did originally to be able to wap out sizes of buckets? Another words make it easier to swap from the claw to the bucket and back again? I only ask because I printed both but don't want to have to go through the hassle of screwing different parts on and off and eventually wearing out the plastic that holds the parts and screws!

[@MarquiseY92]

I vote crane. Then semi!! Great work!!

[@parieth5442]

I gotta say, With these 3d printed mini machine vids, You're really making me want to get buy a 3d printer to start making this type of stuff, Anyway, I was wondering if you've seen a spider excavator before, Building one of those would be pretty crazy considering all of the extra movements, Just throwing the idea out there

[@stevefrench3564]

should look into some hobby grade servos, can get ones even more powerful than that one.

[@urgaynknowit]

How does this only have 600 likes… this is insane!!! People get this man up higher , like his shit, comment, then comment again, and when you’ve commented, do it once more to make the algo notice him

[@ceziukozak]

Best intro ever❤

[@3DWolfEngineering]

worlds best sandwitch💯

[@AnderssonChr]

I'm so excited to make this now! I just subscribed to your workshop and ordered all the parts. Printing the machine will begin this weekend ☺️ Thank you so much for this, it’s really cool what you’ve made. I’ve had my own ideas but don’t know much about the electronics. Hopefully after this and perhaps your other builds I’ll have some experience to experiment with my own stuff. Looking forward to your future machines which I’ll most def be making! (Forklift or telehandler?🙂)

[@zacsmith9146]

@professorboots I heard you mention automation! This would be perfect to help clean up my kids small toys after playtime haha!

[@jamesonimages9741]

I think it would be neat to give one of the 3d printers to the local library where a variety of people could use it for just the cost of materials or something. Not sure how maintenance would work and such though.

[@StevenWilliams-lb9tf]

im new to your channel and love the content your creating, from designing to builds. Have you thought of a mobile crane/truck? that would be amazing!

[@smithwerkz]

I love it man waiting to get electronics. Also it’s at the point time to go from ps3 controller to a real radiomaster air transmitter I’m sure there’s a way but the controls would be so much smoother

[@SivartCustomRCs]

Awesome addition to a great build. Where/how did you get that remote? Is there a vid or link on how to get it? Would any receiver/transmitter work for these provided it has the proper amount of channels.

[@LiamThomas-ve5gy]

I am a student at a school in Australia who has some Zortrax M200s which barely work, and the school has many electronic resources such as Arduino kits which are itching to be put in a 3d printing project. I do not really think the school needs an A1 Combo, but we would absolutely love one of these. Thanks for the amazing video! Also, any idea when a purchasable kit for the excavator might happen?

[@UnrealVideoDuke]

Some schools are literally overcrowded. The class sizes are double of what they used to be. understanding on how much time they have for each course and how many students they need to handle. They could make use of the extra two printers that were given to you.

[@Funfeti]

I love your vids also this thing is a beast

[@The_DropBear]

@professorboots if i join your membership on your site do you have the electronics kit like the skid steer? I have a big printer that can print all the files no problem but im a bit of a noob when it comes to electronics. Just wantedbto see if a kit was avaiable through your membership for the excavator

[@guraaz]

Make it easy for you to change tools on your excavator, for example, to put a jackhammer on the end and lots of other things 😍 I'd love to give a bambulab machine to my nephew, he's learning mechanics and he's passionate about it, like many of your creations :p

[@jefm32]

Solid work my friend 😉

[@cemocan1990]

Any Chance to power it up with 12V?? I think i would be better in terms of power and speed on sand and gras. I just tested it with my son and a little bit more power would be amazing

[@loicdrouin5466]

It would be nice if you put the link of all the parts you need

[@ParkerGrimes-g5b]

I am a student at Forbush High School in NC. We are a small town high school being one out of only two in the county. We are very CTE based and not only me but many students strive to become an engineer or designer someday. We only have roughly 600 kids and not many classes that offer a design element like 3d printing. I myself want to become a mechanical engineer and learn how to 3d print, code and learn how to approach these projects. I think that with the donation of these printers this will help in our engineering and design aspect of our school.

[@mrinmoybanik5598]

Thanks for sharing the step files too for free!

[@ashers_workshop]

Maybe I'm just looking over it, but I cannot seem to find the gerber files for ordering a PCB? is it in his course thing? I don't really mind paying for it and probably would pay for it just to support him, but I want the file to get a quote on ordering one as I couldn't find one the he sold. I may end up just using standard RC electronics like I did with the mini skid.

[@StevenWilliams-lb9tf]

Did you manage to find it, I'm having the same issue

[@SlinkyD]

Had to like AND comment within the first 30 seconds because I got moneys worth and then some. I subbed too. Wanted to the 1st vid of yours I saw. But this 2nd one. 35 seconds in and I'm throwin $$$$ at the TV. I gotta make one with a 56" track width just to flex. And do some stuff 🤩🥰🤑.

[@FalkoRichter]

Is shipping to Germany an option? I started teaching 3d printing and electronics with your skiddi and dumper at the local Berlin elementary school.

[@ventusprime]

you can buy hall sensor module for the n20

[@botlivesmatter9134]

Upsala high school in Minnesota could definitely use the A1 combos

[@JTCF]

Alright, this is what I've got my 3d printer for!

[@bmxscape]

i hope you make a lot of money selling these kits cause they're awesome

[@xwilliams5135]

I would be absolutely delighted to have a Bambu lab printer, I’m young but an aspiring engineer and love 3d printing and 3d modeling, my printer just broke and it is really old so I cannot be repaired, so having an a1 would be amazing!

Where is the voting page? I'd vote for a diy "rwe bagger 288". It'd be awesome to have scale model mining rc vehicles. I can imagine getting some friends together and creating a miniature quary

[@nathanpyatt]

Now you need the semi truck to pull around the skidi and excavator

[@professorboots]

That’s what I’m thinking to

[@nicolaolivi7931]

I am 13 years old and having a printer like that in the laboratory would be wonderful

[@Mr0Randomness]

Shameless plug here, I just started as a STEM teacher at a middle school and we have some flash forge printers but they… are small and unreliable. A bambulabs printer could be used to make some mini skidis at the end of my coding and technology class and improve my quality of life for myself in my 3d printing unit for 6th grade 🙃 On a side note I love and hate you for these projects, I’m currently getting my ender 3 dusted off to start producing my soon to be desktop construction yard. Just drop all of the upgrades before I start printing please!

[@StevenHughes0]

Why are the clips where you are writing on the page upside down?

[@3DDruckHupfer]

[@David_Mash]

You couldn't share a ground for plow and both tracks? That would be 4 wires

[@MatthewSolsky]

2 Things, 1 I say go Dozer, 2 any chance you might have the kit for sale on the excavator anytime soon and or the dump truck kits available on your website for purchase rather then having to order it all ourselves to then put together? I have the 3D print files already I'm just looking for the electronic kits to make them work without having to make several purchases for all of it through different websites! I'd rather just purchase from you and be done! LOL. Either way please keep up the good work your stuff is amazing!!! working on printing the mini skidi now and then gonna order the kit from you the next time I get paid, LOL!!!

[@EpicDesignSolutions]

any online stores in australia i can source most of the electronics needed for this?

[@Kiwi_-]

To anyone who has built this in its entirety, what is about the cost you spent on it? I want to print this a lot but dont know how much the electronics/circuit boards would cost.
