Hi Martin,
Please, read the [Rules & Guidelines] Read before posting.
There you will find the link to the FAQ, where is the answer to that question.
Hope it helps!
Angel LMHi Marta!
First of all welcome to the Thor Community!
The most updated files are the ones located in the Thor Github’s repository. I would recommend you to use that files instead of Hackaday ones.
About the slacks you found on the Art5&6 pieces… Could you post a video to see what is happening? The vertical one sounds like the bolt that pass through the Art56GearPlate is not tightened enough, but without seeing it is hard to realise.
Hope it helps!
Angel LMHi!
The GRBL you have to upload to the Arduino Mega is GRBL firmware. For that board I modified the code. You can see the code in this commit of github: https://github.com/AngelLM/grbl/tree/a4ab72a57b4f2c84cec56b8ef5326d89aad7727d
Also, for the GUI you can check this video I uploaded days ago 🙂 https://www.youtube.com/watch?v=Aas1Xh42xMA
I’ll upload soon a step to step guide to install and run the GUI.
Best regards,
Angel LM
Hi Thalles,
You are using an2560 with a Ramps 1.4, but which GRBL did you flashed to the arduino board? The original GRBL or the one I modified?
The cpu_map_atmega2560.h file is different and maybe that’s the issue. I modified that file to work with the ControlPCB board and not with the Ramps.If you want to control your Thor with Ramps boards you will need 2 units. The first one for the first 3 articulations and the other one for the last 3 articulations. I did it years ago flashing the original GRBL code to the arduinos and sending a gcode to each board separately.
Marlin could be a better option (for testing at least) as it allows you to control 5 stepper motors (X,Y,Z,E1,E2) so you can control 5 articulations with just 1 ramps.
Hope it helps!
Angel LMHi Thalles,
I have 1 unit of the assembled and tested PCB. The price is 60€ + Shipping Cost.
If you agree with the price, send me a private email with your adress so I can go to the post office to check the shipping cost and tell you the total amount.
Best regards!
Angel LMHi Jorge!
To be honest I don’t really know if the screws I used match with the standard M3 screws …
The M3x46 can be replaced with any M3 screw with lenght between 40 an 52mm.
For the M3x28 I don’t know what would be the correct screw. In the 3D design there are not M3x28 screws… so replace it with M3x25 or M3x30. I’ll check the 3D and fix the BOM asap.Hope it helps!
Wow drew! Such a nice image!
Do you mind if I use it (with the proper credit) to add this question and the answer to the FAQ? 🙂Today I tested the Version 1 and it works!
See the video: https://www.youtube.com/watch?v=Aas1Xh42xMABest regards,
Angel LMHi Marko!
First of all, welcome to the Thor Community! 🙂
You are right, in order to keep the Github repo more tidy I have migrated the Builders List to the Thor repo’s wiki: List of Thor Builders
Feel free to edit it and add yourself!Best regards!
Hi Scott!
You are right! And it’s my fault, I didn’t specified that the M5 nut used there is a Self-locking Nut (like this one). I’ll change it at Component list.
Using this kind of Nut the bold won’t be unscrewed by itself!Best regards!
Hi Andrea!
Yay! Another builded Thor! 🙂
Regarding the first question, I don’t really know if the GRBL version that I adapted years ago can work in Jog mode… GRBL v1.1 have that option. I’ll check it and see if I have to migrate to a newer version of GRBL!
About the second question, I’m currently making a basic application to control Thor. It’s called Asgard and it’s available on this Github repo. It’s written in Python and Qt and it’s OpenSource, of course.
At this very moment the aplication does nothing. (I only designed the Graphical Interface) but I hope that I’ll have a basic version of the program in the following days/weeks (just forward kinematics). Maybe I’ll open a thread here to keep the community updated about it.Best regards!
Angel LMHi Aviraj!
First of all, welcome to the Thor community! 🙂
As you say, the current PCB is made in 2 layers, but the first prototype was made using only 1 cooper layer. You can find the gerber files and KiCAD files at github if you go backwards in commits. I think that in commit a45186dc852a9880c0d2699d243ae8d5bddf9bb3 you will find that version of the Control PCB.
Hope it helps!
Hi Shelmak! That project sounds very nice!
When I was designing the last two articulations I wasn’t thinking about how hard it would be to control them… So yes, I end to that confusing articulation hahaha
If I can help you just ask me!By the way, the Drew’s answer is correct (thanks Drew!) Sorry for the late reply!
