Good job for the CAD and Electronics but your 3D print quality is horrible. You need to figure out the good temperature for your filament or change the brand. Otherwise it must be your settings. Your part are too brittle

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 19 күн бұрын
@@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.

What should be the bed size for printing this? I am out for buying a 3D printer. What do you recommend?
@OliverPaff Ай бұрын
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.
@diysumit Ай бұрын
@ would you recommend the bigger A1? That looks great, is there an alternative? There is Kobra 2 Neo, which is sufficiently big but lacks seriously in comparison to A1.
@OliverPaff Ай бұрын
Yeah I would recommend the bigger A1. I haven’t looked into any other alternatives though, but there are some great review videos on KZbin for other printers. Which I would recommend checking out before buying one.

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!!!

@@OliverPaff That would do it. I hate leveling the bed which is why I added a CR Touch bed probe. I recently upgraded to a Ender 5 S1 and I love it. I only had to level the bed once as it comes with CR Touch and it prints over twice the speed with better quality. I could probably get to print faster if I used klipper firmware instead.

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.

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.

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!!!!!

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.

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 3 ай бұрын
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.

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.

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 4 ай бұрын
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!
