Detailed BOM

[Warcorer]

Hello,

The Bill of Materials isn't very detailed on specifications of parts. Could the list please be updated? Issues such as Power Supply 24V a 12V? Is that supposed to mean 24V DC converter to 12V DC? Also stepper nema 17 R 1:5? Is this supposed to mean a Nema 17 Stepper Motor with 5:1 planetary gearbox? Please review the BOM and update the details so it is easier for other people to make this open source project from BCN3D.

Thanks,

Michael

I Am having the same Problems I cannot seem to find the Right parts based on the Description of BOM. common part numbers of users who already built it would be Awesome. I don't know much about this stuff But I want to Learn the most I can. e.g. Belt Numbers, common motor numbers, and maybe places to buy the parts. I am in the US so any help would be Really Grateful!!!!

For the belts I went to PolyBelt

Specifically Here are the: The Belting The 10 tooth Pulley The 14 tooth Pulley

Keep in mind that these pulleys are not predrilled. Witch lets you match to the steppers if you cant find exactly 8mm shafts. You can drill and ream them on a drill press. Use a good reamer.

Stepper motors I got on ebay.

All the fasteners I got at McMaster-Carr

The joint axles I got ebay

The rest is easily available .

Open builds has power supplies and other bits.

Cool. Thanks! @ShopMonkey

Check out the new BOM file https://github.com/BCN3D/BCN3D-Moveo/commit/0866a92501277636f76000a195d8a16d44b5b476 Thanks for the feedback!

Hi, got the same problem. I´m located in Germany and I want to start this project for education. It will take me a lot of time to "redesign" the project because I´m missing the technical details for some BOM parts. Is there anyone who did or is doing the project in Europe. My prefered supplier is Conrad electronic and Reichelt electronic.

Is there anybody out there? :))

HI,

I am based in netherlands and building one. I have almost everything printed out and sourced all components ( I hope). Starting the assembly next week probably :-)

Regards, Richard

We are building the moveo @ the kaasfabriek. Education will be the main purpose. When ready and tested we will use it for school projects. We will provide all the parts and start an educational programm for primary schools and high schools.

[volo63]

Hi, we will also build up the moveo robot arm. Would be nice to work together in a virtuell team. We will use it for our Volkswagen Campus Digital in Hannover to train students.

Here are some links I found for the most matching stepper motors, with cheap shipping in Europe. (the 34mm NEMA 17 is a 0.9* version, 1.8* was sold out)

I have to join the chorus here: The current BOM is a bit of a joke.

First, why on earth have you chosen to make a PDF of a screen dump of an Excel sheet?! Come on, guys! Open the Excel sheet in LibreOffice, then export it to an open format!

Secondly, specifications such as "Chrome steel smooth bar-134 mm" are pretty useless. How can I know which diameter is required?

[chexov]

You guys know you can make pull request and fix it instead of complaining right? This is how OSS works pretty much.

[bullestock]

@chexov How can I do that when a) no source exists for the BOM b) I have no idea what the specifications are for those "smooth steel bars"?

[bullestock]

@AnykeyNL do you have any details on items such as steel bars etc?

[bullestock]

Digging around in the forum, it turns out that the steel bars should be 8 mm.

[volo63]

Hi Torsten,

 

we already worked our own BOM.

I don´t have any experience with github.

If you are interested in our BOM I could send it.

We also made the first  -bad - expieriences with the cheap motor drivers.

Also we have some not solved issiues.

What is your robot arm status?

 

greetings

volker

if you need I could ask in the workshop to produce more.

Do you need the cylinders?

@volo63 I found a BOM in Excel format in the forum, but I would like to see yours too. I plan to produce an improved BOM and upload it to github. (I have not yet started on my arm, I am just doing research ATM).

I am not sure I understand what you mean by "cylinders"?

[anyrules]

Hello All,

I have started to print out the components and meantime I looking for components and Fasteners. Unfortunately it's really do not easy to recognize all components based on the PDF. (Some of them withdrawned from the market) First we need to print out after we can concluded for the parts. If somebody have a fresh detailed BOM and send to me I really appreciate it. Thanks in advance, Regards Istvan

[volo63]

Hi Istvan, We will send our updated list tomorrow. Sorry, saw your email too late. Greetings Volker

[CaptainMack]

If you could send the BOM to [email protected] I would be grateful!

[elstanto]

Does anyone have more information about the M4 and M3 brass inserts? Are there recommended lengths etc? Also, are the spacers aluminium ones - they aren't in the BOM!?

Also, what are the selfoil bearings at the end of that section of the list? How are they different to the earlier bearings?

[SuperiorArri]

Hi, can you please send me your detailed BOM to [email protected]

Thank you very much!

[elstanto]

Can we get the detailed BoM in a forked repository or something publicly available online? It seems bad practice to turn this issue thread into an email request page...
