Regarding your video, woah! Your “fat” Thor looks amazing! I can’t really notice visually the difference of the added width in the pieces, but if it works it works!
I’m not really sure about how it could be managed, but it would be nice to have your redesign available for other people in the same situation of being unable to find the steppers I used. Maybe you can do a fork in GitHub? Let me know if you like the idea!
About your doubts:
1. Yes, the zero position of Art56 is close to the endstop. I have to admit that it’s a bit confusing because real robots have the zero position in the most extended position… Maybe is something to add to the To-Do List hahaha.
And, to be correct, it only does the home of the 5th articulation. I didn’t find an easy way to find the home position of Art6, so I do it manually :/
2. About the stability of articulation 4… Yeah, it’s a known issue. I had to print several times the pieces that forms the bearing to get a close adjustment, and even with that it has a little play… In the endless To-Do List is noted to substitute that “custom” gear with a commercial one. Years ago, when I designed the robot I didn’t find a cheap bearing that could be fitted in that articulation, but recently I think I have seen some plastic bearings that could be used for that task.By the way… What a workshop you have! What envy! And that Iron Man armor… what a blast!
I don’t know turkish, but you have a new subscriber! Can’t wait to see more videos! 😀
PD: Whenever you want, post an image of your Thor, a location and an url to add your creation to the Worldwide Section 😉
OK, it seems that was pending of my approval because of the URL inclusion… But it never notified that to me hahaha… Now users should be able to post links without me having to approve them all.
I found the post in your website! Your Thor is impressive! 🙂
I’ve added it to the Worldwide Map 😉
Hi Mohamed!
I actually designed it to be a Shield for an Arduino Mega… The PDIG1 Connector is supposed to connect the shield to the Arduino Mega.
Also, there are inputs for the opto sensors, labeled as P1, P2, P3, P4, P5, P6 and P7.That’s strange… Maybe you have not downloaded every file?
Please follow this steps:
1. Go here and click on Code green button and then “Download ZIP”.
2. Go to download folder and unzip it
3. Open KiCad
4. On KiCad click on File > Open Project
5. Navigate to the unziped folder Thor/electronics/ControlPCB and open the ControlPCB.pro file.It should properly open the KiCad project, if you still get this error let me know and I will look for another way to send you the kicad project 😉
Okay, so the serial communication seems to be okay and the steppers seems to be working.
So… it may be problem with Asgard. I’ve tried it today and it works for me, so let’s make it works for you 🙂
Quick check:
1. Be sure that you have installed the required dependences:
– PyQt5:python3 -m pip install pyqt5
– PySerialpython3 -m pip install pyserial2. Launch Asgard using Python3:
python3 asgard.py
3. Post here if you receive any error or if it works!Hi Mohamed!
I think I found a commit with the gerber files of the first version of the ControlPCB (single layer): https://github.com/AngelLM/Thor/tree/a45186dc852a9880c0d2699d243ae8d5bddf9bb3/electronics
Check it out and tell me if that was what you were looking for 😉
Hi Colin!
Thanks your words, I’m glad you like it!
Regarding the Asgard issue, have you been able to execute a Gcode command via Arduino IDE Serial Console? (More info about this in Firmware Documentation)
If that is not the problem, maybe there is something wrong with Asgard´s python code… And I´m pretty sure that would be this line:import serial_port_finder as spf
I´ll take a look to it meanwhile!Hola Iván,
Habría dos maneras de hacerlo. Por un lado, generar un archivo .gcode y ejecutarlo con el Universal Gcode Sender.
Por otro lado, se puede programar un script en python que envíe por el puero serie las instrucciones de movimiento (un ejemplo de ésto último puedes encontrarlo en este repo)
Espero que sea de ayuda!—-
Hello Ivan,
There would be two ways to do it. On the one hand, generating a .gcode file and running it with Universal Gcode Sender.
On the other hand, you can program a python script that sends through the serial port the movement instructions (an example of this can be found in this repo).
I hope it helps!“The first variant probably allows to connect the male PCB connector directly into the Arduino female connector?”
Yeah, you are right!It doesn’t matter the direction as long as the connections match with this diagram would be ok.
