Hi again!
I just did a clearer electronic schematic that you can see here.
The references can be checked in the Component List wiki page.Hope it helps!
Hi Triumph! You can check the KiCad files uploaded to the repository. But you are right, I’ll make and upload a clearer diagram as soon as possible!
Best regards!
Hi Antonio, I have several ControlPCB V1.0 and mats for assembly them.
What are you looking for? Only the PCB? The PCB+Mats or an already assembled PCB? I’m from Spain, and I think that the shipping cost to Italy is about 5€ (not really sure about this).Hi guys!
After several of days thinking about this and evaluating many possibilities, I think I have a conclusion.
I made a wiki inside the GitHub repository, and it can be edit by anyone. I have migrated the “Component list”, “Thor Builders” & “FAQ” info to the wiki.
In this way, everyone can access to the wiki and edit it. Also, there is a register of changes, so it can be restored in case of “vandalism” or something like that.
This wiki is very easy to edit, enter to the wiki clicking in the “wiki” tab in the repository and edit the page you want just clicking in the “edit” button inside that page. Easy.
If you want to create a new page click on “New Page” button. That’s it. The only thing you have to know is the Markdown format, I suggest you to visit this page where it is explained very well.What do you think?
Best regards,
ÁngelNo problem 😉
BTW, I have enhanced the Wiring Diagram of the Control PCB, now is easier to see how the Arduino is connected with the Control PCB 😉
Best regards!
Hi guys! I just finished the wire diagram of the ControlPCB v1.0: https://raw.githubusercontent.com/AngelLM/Thor/developer/electronics/ControlPCB/WireDiagram-v1_0.png
Tell me if you see any error or you have any questions about the connections.
Hope it helps!
Hi all!
;currently tested (little by little
because I didn’t have much spare time right now…) and I have found at
least 3 bugs in the current design of the ControlPCB.
These bugs are easy to fix, but I’ll update the electronic design in order to have a bug-free PCB.The bugs I have seen so far are:
- Solder
pads for the Power and Switch terminal blocks are in the incorrect
side. Quick fix: Solder it through the hole or applying some solder
paste in the solder pad before introducing the terminal block. - The
Tool control pin is currently connected to the Mega’s pin 40 which is
not a PWM pin. Quick fix: separate the Tool wire from the ribbon cable
and connect it to a free PWM pin (for example: pin 7). - LEDs are
too bright. I have to check the values of the resistors since the leds
are so bright that them can hurt the eyes. Specially the USB one. Quick
fix: Probably a higher value of the led resistors will solve this minor
bug.
Except for that bugs, the PCB works well.
I will upload soon the fixes, the grbl version for this board aaaaaand a diagram of the PCB connections.
Best regards!
Hi Triumph!
What steppers did you buy? Can you link a datasheet or a link to the shop?
Anyway, if the only diference is that your shafts are a little bit larger I guess you can make the slots larger without problems, I don’t think it will affect the structure.
Hope it helps!
Hi Hotam,
You are right, the current design of Thor only uses 7 steppers, so 7 drivers are enough.
I designed the new board capable to control up to 8 steppers in order to be able to add another degree of freedom. (I was thinking to add rails on the base)Hope it helps!
Awesome! I really like that hammer! 🙂
Be sure to make a picture of your Thor (when assembled) grabing it! hahaha
Nice to know! I’ll be finishing it tomorrow, I guess. And probably I’ll test it too. I hope I designed it well… hahahaha
