For the assembly details you can check this post: http://thor.angel-lm.com/forums/topic/is-that-pcb-true/
About the MPNs, unfortunately I don’t know them, they would have to be the ones to look for them
Best regards!
I assume the links you are referring to are to the Thor repository wiki (currently deprecated).
The links you will find in the BOM of the project website are up to date and will take you to the correct model.Anyway, the links to the components are for convenience, if you prefer to buy from another store just check that the torque requirements are at least 26N.cm and the motor consumption is around 0.4A powered at 12V.
Best regards! 🙂
Hello!
As it can be read in the README of the Thor repository, the wiki is deprecated and for updated information the project website should be consulted.
As for the terms “screw” and “bolt” I have not found a unanimous definition that clarifies the difference between one and the other. In any case, I am referring to this type of elements: Image
Hope it helps!
Hello!
First of all, congratulations on your work! I hope Thor has been useful for the study you have done 🙂 I’m quite interested in the topic, so I hope to have time to read it soon!
Your robot has been registered on the Worldwide page with the number 34 and it’s the first one from Greece! As the map only allows me to add one link, I have added the thesis in English so that more people can read it. However, as they are also academic works, I have included both in the ‘Academic presence’ section (just below the map).Welcome to the Thor family and thank you very much for sharing your work with the community 🙂
Hello!
It looks good to me, I cannot see anything wrong from the photos. Why do you think is quite wrong?
The only think I miss is the yellow wire that I shared with you in the previous photos, maybe they will solder it at the end. Apart from that I think is ok.Hello AliSintax!
You are using the same stepper model for articulations 5&6, right? If so, you are experiencing the same issue with those steppers?
I can think in 3 possible issues:
1. Maybe the art4 driver is broken and is not working well. To check it just switch the driver with any other and try to move the motor.
2. The wires of the stepper are not well connected. Sometimes the manufacturer messes up with the position of the wires in the connector of the steppers. They should be placed in order: 1A1B2A2B. A quick way to check the wires is, with the motor disconnected, connect a wire between two of the motor connector pins. If you try to turn the motor shaft by hand and it generates a higher resistance than when the wire is not connected, it means that the pins you have connected correspond to the pins of one of the coils (1A1B) for example.
3. The max speed or acceleration value is set too high. Check that the $parameters match with the ones posted here.Hope it helps!
Hi Eduardo!
Welcome to the Thor community! Feel free to ask any question you have during the building process 😉
I have just found the last PCB that I am not going to use.
Let’s see if this week I can go to the post office to ask for the cheapest way to send it to you 😉Hello Evgeny!
I welcome you both to the Thor community! I am delighted that you have ventured into this project with your son! I think I would have loved to do something like this when I was a kid!
I’ll keep an eye out for new episodes! 🙂
Hi! There are a couple of things you should check with the manufacturer:
1. The PDIG1 2×18 male connector should be mounted on the other side of the PCB.
2. The female connectors should not have that gap between the PCB and the connector. They should be fully supported on the PCB. I think it’s because they are using hand-cut 8-pin strips. Instead, I recommend using 32-pin strips, cut only on one side.
3. One of the pins of the PDIG1 connector should be removed and a wire soldered in its place. The pin in question is as follows:
Apart from that, I’ve had a look at it and the rest seems to be fine.
Best regards!I may still have some unsoldered PCBs at home. Let me take a look at it and let you know this weekend 😉
Hi, I’m so sorry!
Sometimes Aliexpress changes the products to which the links redirect and, although every so often I check that the products are correct, there are times that I do not arrive in time 🙁
I’m going to do a general review of all the links, just in case there is any other link that is not correct. Thank you very much for the warning!Hello!
What a hype you’ve created with just one post! I love it!
Welcome to the Thor community!
I also made an attempt to add that linear axis a while ago, but in the end I didn’t finish it. I can’t wait for you to show us something!
Hello!
I’m happy to see you here!
I found your video about Thor and I enjoyed it and the content you were creating 😊Do not hesitate on sharing all your progress if you decide to build your own Thor! 🦾
