@@OliverPaff how did you learn to code? I aspire to try this one day

[@OliverPaff]

@benv9771 KZbin and google. I still don’t know much about coding, I learn the code as I work on the project. So if I get to a point where I have no clue how to code something I’ll just take a break and learn that part. It’s probably not the best way to learn how to code but it has worked for me so far.

Great work, I always love to see someone doing creative and smart things like that. Someday I will try too.

[@MagnusForte]

1:42: Well add a couple of layers and a Brim before the actual piece starts to be printed. Also, use Stick Glue, over the printing area (over bed printing) it is a little messy but, allow the first layers to stick properly and then removing the piece will be easier...finally let the printing piece cool down before removing and get one of those Art (iron) spatulas that are very tight and will do a more easy job, and don't rush the removing, breath, relax and take it easy...it will come out nicely!!!

[@EngineerNotFound]

Yeah, I had similar issues with the servos. I'm using an ESP32 in my project, and trying to drive just a few motors from the thing was causing the glitching. I'm using 8 servos, but at most only 2 are required to move at the same time, so I thought it would be fine. Then I added the PCA9685 and it was all fixed. I went into it blind and was learning as I developed things. Thankfully I didn't fry the micro controller. It's understandable though that, when you're new to certain types of projects, you're gonna overlook things, or be totally unaware of things you should know. I guess that's why research is important; Anyway, well done on getting the robot to work - a robot is on my bucket list; but that's a long way off.

[@Walt1119]

Great project! Some tips on ur printing issues, using pla(I'm assuming that what ur using) use glue stick on ur bed after u wash it with soap and water and dry, important! It helps with adhesion but also helps as a release agent for ur parts. Set bed temps @ 50-60c, tip temps 225-230c, I use sunlight pla+ excellent filament and inexpensive too. Don't run over 50mm on speed, Ender3's don't like speed. Hope this helps, keep up the great projects!!!!!

[@jessegrantduron9632]

Subscribing because I’d like to see your progress as a design and builder! Good work!

Thank you so much!

[@NeoRelic-o8p]

Keep printing robots ❤

[@cinnamon3556]

I think you print bed is way too high, it shouldn't be leaving that many marks on the plate, generally people say to level is so that a piece of paper can slide between the nozzle and the bed, but I find that I need it to be a little closer to stick well. Also personal opinion but I would recommend buying nuts and bolts and printing much smaller pieces that can be easily bolted together. It's more work but you save filament, print time, your mind if you have to reprint a connection piece 5 times. Also I buy aluminum dowels from a local hardware store and use them for structure so that I really only have to 3d print the connector kind of things and it saves me a lot. (I just know how frustrating it is when a 9 hour print fails after 8 hours) Also I'm not hating, I loved this project, never stop creating stuff dude!

[@OliverPaff]

Yeah after I printed all these pieces I leveled the bed and it was much better quality. I usually just get a piece of paper and fold in half and it’s good. Also nuts and bolts definitely would have been a better idea. I was thinking of using them but decided not to. However, after I printed everything and started putting stuff together I regretted that decision because it definitely would have made the project easier. That’s a smart idea to use aluminum dowels. I’ll definitely consider using them for the 3D printed parts when I build the next robot arm. Thank you so much for the feedback!

[@mach10point4]

Hey man this is sick!! Hope you keep creating. Stuff like this will take you far. For the print issues, first off a high quality glass/pei plate and a pretty much a must. Then, regular cleaning and adhesion (glue sticks, etc) is also critical. Get your bed leveling dialed in, experiment with some first layer settings (maybe try turning fan off during the first few layers, run a little hotter). Try a temperature bridge, layer adhesion in general looks like a bit of an issue. Hope these tips help, I’m a total arduino noob but want to at least help with the printing side of things.

[@PaulGonzales-e3b]

Impressive! Keep building man

[@BadDevException]

Hey man, incredible work on that robotic arm, you made a super clean build, if you consider pursuing an engineering career I'm sure you would enjoy it! How did you get started in designing 3D and embedded systems with Arduino?

[@OliverPaff]

Thank you! I got into all of this mainly because I took a CAD class my freshman year of high school and decided to get a 3D printer after taking the class. After that I just started designing and printing some simple stuff and then eventually decided to start doing some bigger projects involving arduino.

[@RyouscxreD]

i loved the project, and i recommend you using a servo driver which will make it a lot more smoother and stable and you have enough room for an servo driver like a PCA 9685 driver, although the outcome is lovely

[@OliverPaff]

Thank you. I actually added a servo driver later on in the video since the servos couldn’t draw enough current, and it helped a lot.

[@RyouscxreD]

@@OliverPaff nice to hear that

[@kalafiorkrzysztof1303]

Ceep up the good work buddy!

[@abdojr4191]

Hi, I’m a beginner in design and I don’t know how to design these things. I searched on KZbin but couldn’t find any 'good' course to learn CAD design and then print it. Could you give me a good source to learn it? I’d appreciate it.

[@OliverPaff]

Personally I just messed around on the CAD software and designed random things. Eventually working my way up to more complicated stuff. However, that does take a while. I would recommend a combination of KZbin and just messing around with the software. I also found it hard to find good tutorials on KZbin so maybe doing more by yourself is better. Start off with simple shapes and making cuts and holes, just to get a hang of the basic tools of CAD. Then move on to designing different things with more complicated shapes and parts. If you have any more questions feel free to ask.

[@aaamott]

Nice work! If you decide to upgrade your ender, consider the belted z mod (only costs maybe $20) and a new fan duct, plus a knockoff CHT ($2) if you don't already have it. Between those, you get way more reliability out of it!

[@OliverPaff]

I actually just bought an A1 mini but I still have the Ender 3 so I’ll have to look at some of those upgrades. Thank you!

[@nhnova1452]

@@OliverPaffhow is the A1 mini? Thinking about either getting that or the regular A1

[@OliverPaff]

@nhnova1452 It’s extremely easy to work with and great quality. However it is very small so if you want to print bigger items I would recommend the regular A1.

[@Lazarus1212]

First of all I would like to say thanks for showing the work on this project with all your slip-ups and mistakes, really full respect. You have shown what it really looks like and how much effort it took. I think I'll use your projet myself because it looks really well thought out. For now I'm waiting for you to update the project on the onshape Robotic Arm V2, so far I'm watching and analysing what's what. It looks really good. I miss showing how the motor pinion is connected to the moving part.... You didn't use any gear ratios (cycloidal gear?) just a direct connection? I need to do some more thinking on this.

[@jesp8329]

awesome broo

[@OliverPaff]

Thank you

[@buildthenlearn]

Nice project, and a perfect timing. I just got my first printer (A1 Mini) and I was looking how to get started with robotics. I was looking at the cad model and have few questions. How does the rotating base (part 3) connect with the arm (part 10). Also when I try to make the arm's length smaller (too big for my printer) from 5inch to 4 inch the back cover (part 11) just disappears. And if you don't mind can you provide the links for the electrical components and how do you power the servo driver.

[@OliverPaff]

There should be a disc that connects to the motor that goes into part 3 the disc then connects to the arm (part 10). I would recommend however to redesign it yourself because I designed this in the worst possible way so it’s not the easiest to build. However I am working on getting the parts fixed and making it easier to put together. Also I will link all the electrical components in the description. The servo driver is powered by a 5V 5A power supply. Also about the part disappearing, it’s probably because if you go in and edit the length it messes with the other features causing failures within the design. To be honest I have no clue if there’s a way around that. I would recommend probably finding a better design than mine that’s easier to work with.

[@buildthenlearn]

@@OliverPaff Thanks, you designed it better than I could.

[@jonmurch960]

I just finished my first one last week using an esp32 board and a ps4 controller but mine is much less stable. i want to make one with steppers and maybe planetary gears in the future but now im making an rc airplane. super cool design.

[@OliverPaff]

That’s awesome. I bet being able to control it with a controller is fun. Also using stepper motors and planetary gears is a great idea. I originally planned on building a bigger arm using them but instead went with a smaller one with servos. If you ever build one you should definitely post it, I would love to check it out. Also good luck on the rc airplane.

[@jonmurch960]

@@OliverPaff Yea i wanted to make the stepper controlled arm but i dont have experience with steppers and i wanted to work with stuff i already had which was a bunch of servos. I have an extremely modded ender 3 thats just piling dust and im considering hijacking the motherboard to control all of its steppers and making a new robot with that but thatll be a while.

[@fatihcemalcan3280]

Nice Design. You should use smart bus servo motors instead of these RC servo motors. If you use bus servos, you will be able to move your gripper precisely.

[@tomfoolery2913]

How are you doing inverse kinematics for J4, J5 and J6? I understand the geometric solution for 3dof but wondering how you've done the IK for the remaining 3dof. Seems a lot more complicated when adding the additional dof. Also are you interpolating your servo positions? May help reduce the jerk

[@OliverPaff]

@@tomfoolery2913 I actually only did the geometric solution for 3dof and then for the J4, J5, and J6 I just had a couple lines of code that switched them between two angles. Such as the claw head going up and down. It’s definitely not the best way to do it, however doing the inverse kinematics for the other 3dof was more complex than I was wanting to deal with at the time. So I just decided to kind of cheat my way around it. Also I did look into interpolating the servo positions but I never actually went through and did it. That is definitely something I’m planning on doing for the future version though.

[@Gavo9649]

Looks amazing great job! Me and my friend are currently trying to make a robot arm as well And I was wondering how you went about supplying power to everything and what you used for that. Thanks a lot!

[@OliverPaff]

Thank you! I used a 9V 1A arduino power supply and a 5V 15A power supply for the servo driver. I will link them in the description. If you have any more questions feel free to ask. Good luck on the robot arm.

Did your electric bill increase when you start printing?

[@OliverPaff]

I asked my parents and they said they haven’t seen a large difference. After looking it up it seems that it doesn’t add much unless you are printing a lot or with many printers.

[@SkyfalconTin]

@@OliverPaff my last bill is $175 when it usually $90 - $100. But it just probably summer and we ran ac.

[@aaronalquiza9680]

for future reference: 250W is the max power draw of Ender 3 v2. if one prints 24x7, and average kWh charges of power company is $0.12: 250 x 24 x 30 = 180,000 / 1000 = 180 x 0.12 = ~$21.6/month if constantly printing

[@sheheryarahmad9721]

I looked at the file you sent, the part where the arm connects with the base is missing. Could you look into that?

[@OliverPaff]

Yeah, when I was working on it I must have turned off the visibility. I just fixed it. You can check the side bar of the assembly and see the parts, they should have an eye next to them. If you click it, it turns the visibility on and off.

[@OliverPaff]

Honestly you can make the project without making adjustments to the files. You will just have to do some sanding and instead of screws you will use glue. Some people don’t want to sand or would prefer to screw everything together so I just mentioned that in description just in case people wanted to change the files to their liking.

Hey, I wanna ask if the files are updated or not bc you mentioned that there were some problems with the model in the description. And also I just wanna say, your amazing, genuinely

I have fixed most of the issues, however I kept it so that the pieces can be glued together. If you would like to change it so that you have to use screws instead, the CAD files are available so you can change them easily. Also thank you!

[@el_teodoro]

You should dry your filament. Calibrate your 3D printer as well, it looks like it's over extruding. I also recommend you use gyroid infill, it's more stable, never had a part break mid print.

[@OliverPaff]

I actually just got a filament dryer and I’ve definitely seen improvements in the quality. I will try calibrating it, I haven’t done much calibrating when it comes to flow rate or anything like that, but I definitely need to. Also I will check out the gyroid infill, the current infill I’m using is definitely not the best. Thank you for your feedback.

What should be the bed size for printing this? I am out for buying a 3D printer. What do you recommend?

I printed all of this on an ender 3, so 220 x 220 x 250 mm is probably the best bed size. However I have recently switched to a Bambu labs A1 mini and it has amazing quality although it has a smaller print bed. I would recommend doing more research based on what you want but the best size for printing this project would be 220 x 220 x 250 mm.
