GUS documentation in GitHub.

I added some string diagrams. It is essentially exactly what guizmo posted.

Yours is prettier :(

( :lol: )

It's good you add them to the repo. They're absolutely needed. It was in fact the last thing I had to clearly understand to finish the mechanics.

I see that you have just uploaded the stringing diagram on GitHub, but how will the stringing look when using tuning pegs mounted on the slave arm? I know the STL's are not made for the tuning peg design, but I decided to drill a few holes in the print and mount the tuning pegs anyway :)

Tuning pegs on the slave arm is how I originally did it but it breaks the linearity of the design. However, if the string and the tuner are going on the slave arm then it depends on where you position them. If you want to upload a pic then I can suggest something for your setup.

I have attached a photo of the placement of the tuning peg.

I actually thought the tuning peg was added in a new version of the design since I can see it on most of the pictures I find of Gus :)

You can see in the image below how the tuner sticks out the back of the motor arm.

All versions of GUS have the tuner. My prototype that I didnt publish had the tuner on the slave. For easier calibration it is now on the motor arm. Let me know if you still want to go with your placement and I can draw you up something.

So, do the up-to-date STls have mounts for tuners?

Pretty sure I have the older style spools printed up, shall I stick to the first diagram.
Also pretty tempted to go for the metal spools linked in the spool thread at one point, will that also be the first diagram??

@ChrisK: If you don't have enough power with 1 loop like the first diagram then go to 2 loops like the second.
