I made a small upgrade of the shoulder servo. The small potentiometer broke, so I use a larger potentiometer with a 6mm shaft. It’s the olny part that I have changed,but I think the same principle can be used on all potentiometers. The new potentioneter can rotate 270 degrees instead of the original 180 degrees, so the servo mapping has to be…En afficher davantage

Hello Mats!
That for sure is a safe pot!!
But you didn’t use my latest pot holders, that means your parts can no longer fit PivTit and RotTit of the latest version…
I guess, it’s because you already had PivTit and RotTit printed from the previous version. I like your little potentiometer board option, it’s handy for to simply disconnect.

  Hi Gael.
  I added two versions of the pot holder to Thingiverse. They fit the latest version of the shoulder. One version is without the cable guide and the other with the cable guide.

    Great Mats !

Before I can start with my complete InMoov, I need to upgrade my UM2 filament spool-holder.
I’ve ordered some COLORFABB_XT spools with 2.2kg filament 🙂
Not sure if XT filament is the right choice for some mechanical parts.

Mindless replied il y a 9 ans et 3 mois

yep… Colorfabb is great stuff, iv tried every brand/type out there ,, i do a lot of printing,,, In Australia i use « Blueprinted » filaments which is pretty good quality for a cheap filament Colorfabb is hard to get here and its bloody expensive..
I only use PLA you would surprised how tough the stuff when printed correctly – you wont have any…En afficher davantage

  Thanks for your information.
  I get lucky to live in the Netherlands, the shipping costs are free when I order one spool.
  And with the 2.2kg spools it’s 30% less in price.
  
  I’m sure I need to play with some settings (temps and max speed).
  I hope to start this evening with some tests 🙂
  
  I’ve used CollorFabb PLA for some time now and this prints…En afficher davantage

    Its worth having a go at trying other other filaments but iv found you really cant beat good quality PLA when its printed correctly,, its hard so its good for gears and moving parts It prints like a dream compered to other filaments,,, and it doesn’t destroy the planet,,,
    I’v been R&D on 3d printers full-time for about 4 years now, mainly on d…En afficher davantage

      CollorFabb PLA is good material anyway.
      XT can handle a higher temp when it’s printed, this part is a positive thing if InMoof stays for a long day in sunlight.
      So maybe I will use XT for some outside parts and all others with PLA 🙂

The new printed shaft fits well and it looks that it can handle the rotation.

Perry replied il y a 9 ans et 3 mois

Nice. I am printing up my version now. See my post above.
Gael Langevin replied il y a 9 ans et 3 mois

This is certainly getting along well !!
Following your progress from close by, Marten!

So, the new hexagonal shaft / Small_Gear and Servo_adapter files are uploaded 🙂

I will test this soon and will share a video later this week.

Thanx Marteen you are very fast, Great
- Marten de Groot replied il y a 9 ans et 3 mois
  
  Haha 🙂 If the time is there, it can be go fast 😉
  
  How about you, any progress with your « Right » hand ?

    slow but sure, when I finish it , you will know, Marten 🙂

Marten de Groot a publié une note il y a 9 ans et 3 mois

Instead of a DogBone shaft, I’ve designed a new small Wrist_Gear and servo-adapter and will use a 6mm hexagonal shaft.
I hope the 6mm hexagonal shaft is strong enough 🙂
Tomorrow I will print all parts and if it works fine, I will include these parts to the Wrist upgrade set @ Thingiverse.

rodolfo rojas replied il y a 9 ans et 3 mois

Great, infill 90% surely will give it enough strength
- Perry replied il y a 9 ans et 3 mois
  
  Almost done with my design. Just waiting for filament to arrive in the mail so I can print. My design will use many of Gael’s original servo bed and has a printable shaft. HAd to spend a fair amount of time hollowing out the arm and wrist parts but there is a straight run for all the tendons now.

    Hi Rodolfo and Perry,
    
    @linuxrodo
    Yeh, I think it’s fine 🙂
    Just started to print all the parts.
    
    @perry-scartozzi
    I can’t wait to see your idea 🙂
    Which program(s) are you using, during re-editing Gaël’s STL files ?
    - Perry replied il y a 9 ans et 3 mois
      
      I am using Solidworks. I explained to Gael below in my thread about my back cover how I modify the STL files.

        Thanks Perry,
        To share your info about that ! 🙂
        
        Almost done with all the parts.
        Only missing the small Wrist gear.
        
        The shaft and servo adapter feels good enough for me.
        I hope the length from the shaft is OK 🙂
        If yes, I will upload all parts to Thingiverse in 30 minutes 😉

Really Fantastic, I’m « hands on it » , and ready to upgrade my inmoov’s right hand

Today I received my new Lenovo Thinkpad 8,3″ and the DogBone shaft 🙂
Later this day, I hope to finish the last things for the new Wrist DogBone shaft.
(I need to change some small things to makethe DogBone shaft fit between the small Wrist gear and to the servo DogBone adapter)
