  great Marten ! i will try reduce print speed with 100% infill . 226° is not too hot ?? I use simplify3d no Wall Thickness settings just perimeter shell .
  - Marten de Groot replied il y a 10 ans et 5 mois
    
    Hello Anthony,
    
    226° is a high temp, the UM2 has a lower temp as the display is showing.
    And with this temp I get good results 🙂
    Sometimes I set the temp a bit lower, after the first 10 layers.
    
    Do you have a picture from your end results ?
    If yes, it good be handy to give a better advice where it go’s wrong.

      - Marten de Groot replied il y a 10 ans et 5 mois
        
        Looks good Anthony, I think only you need to start the fans from a higher layer !
        I see a lot of warping at the bottom side, this happens when the PLA is cooling down to fast.
        The best way is to start slowly with the fan speed around layer 30 (3mm if you are using 0.1mm layer)
      - Mats Önnerby replied il y a 10 ans et 5 mois
        
        Also check that the print bed is close to the nozzle. If the distance is to far, the first layer will not stick well to the bed. The first layer should create a solid piece of plastic without gaps.

Gael Langevin replied il y a 10 ans et 5 mois

It is interesting to see how 3D printers have improved in 3 years.
When I started the project, most printers could only print with raft which would have been a pain when assembling together those two piston parts.
Today with heated bed and good sticking surface it becomes easy to print parts in different directions. Also support printing is so…En afficher davantage

The new dual track servo pulleys interfere with the cover of the hand. If you use them some material needs to be removed from the arm cover to make room for the front middle pulley. Thanks to Juerg who warned me that this could be a problem.

Hi Mats,

Mats Önnerby replied il y a 10 ans et 5 mois

Hi Marten. I just cut of a few mm’s of the hand cover support. It’s only there to support the structure during print. I don’t want to replace the dual track pulleys since they work very well. Have a look here for a demo https://www.youtube.com/watch?v=b5S-8hjsMr8
- Marten de Groot replied il y a 10 ans et 5 mois
  
  Hi Mats,
  
  I’ve seen the video and the results are perfect !
  The option was more meant to update the Pulley’s for other InMoov builders, how like to use your Pulley’s, so they haven’t to cut anything 😉
  - Mats Önnerby replied il y a 10 ans et 5 mois
    
    From a math point of view, an excentric pulley will work very different. With two tracks, it’s just linear movements. The excentric can only work between very limited angles. With two tracks, you can rotate any angle. The ratio will still be the same.
Gael Langevin replied il y a 10 ans et 5 mois

Maybe reducing the filet height for the tendon, this way the pulley would be less high and wouldn’t cause a problem with the covers of the for arm.

  - Mats Önnerby replied il y a 10 ans et 3 mois
    
    No change to MRL, except that you may have to change the max and min values for each servo that controls each finger, but thats someting you probably will need to do anyway.

Hi mats
Currently on vacation in Japan (they have some nice robots here too but InMoov is not popular here).
I can’t draw you a picture with my mobile but look at this – the servo has to travel 17 plus 27 mm for complete opening and closing. Depending on the servo you have installed (my mg995 can do about 210 degrees) this will be…En afficher davantage

Mats Önnerby replied il y a 10 ans et 5 mois

Hi Juerg. I appreciate that you want to help. But from your answer, it is obvious that you don’t understand the basic problem. It has nothing to do with centering the servo. The servo needs to pull 27mm on one side to close the finger, while releasing 17mm on the opposite side. That is a difference of 10mm. Not a sum of 27 and 17. To open it…En afficher davantage
- juerg replied il y a 10 ans et 5 mois
  
  Hi Mats
  I think I got your point. When doing my first pulleys I had problems that they interfered with the cover, adding a second track would require lower built servos or a modified servo-bed? And the string-guiders will need to be adjusted?

Mats Önnerby a publié une note il y a 10 ans et 5 mois

A litte update to expain the reason that I redesigned the servo pulleys. I use the fingerstarter to explain. In the first picture the hand is open and both lines are stretched. On the second picture the hand is closed, but the lines are not stretched any more. To close the finger the servo pulls about 27mm and releases 27mm on the other end. But…En afficher davantage

- juerg replied il y a 10 ans et 5 mois
  
  hi mats
  Maybe I see things the wrong way but I do not understand why you have to modify the pully. Set your servo to the middle position than add the pully with a 10 mm offset towards the closing side. In MRL define a mapping that covers the 44 mm range for the full movement with your servo?

Very good idea the « double pulley ». You get the same results for the pinky and middle finger ?
- Mats Önnerby replied il y a 10 ans et 5 mois
  
  Almost. Even if the pinky moves a shorter distance than the middle finger, the ratio between opening and closing seems to be almost the same. I only use one pulley size for all fingers.
Gael Langevin replied il y a 10 ans et 5 mois

Very good idea!

Mats Önnerby a publié une note il y a 10 ans et 5 mois

I have made new servo pulleys for the hand. They have two tracks with different diameters, since you need to pull a longer distance to close the hand than to open it.http://www.thingiverse.com/thing:1074604

Revwarguy replied il y a 10 ans et 5 mois

This looks interesting – How would you describe the improvment to the hand’s movement?
- Mats Önnerby replied il y a 10 ans et 5 mois
  
  To close one finger you need to pull 27mm but to open it again only 17mm, The 10mm in difference will result in that the lines easily fall out of the tracks, The servos will also have a deadband of 10mm before they start to pull, With this construction the lines will be stretched all the time, so the fingers will keep their position better.
Revwarguy replied il y a 10 ans et 5 mois

The reason I am asking is if you think the springs that were introduced to keep the strings tight would still be needed ?
- Mats Önnerby replied il y a 10 ans et 5 mois
  
  Good question. I don’t think that springs are necessary, but if you turn the wrist, the lines will be tightened. So you have to compensate for that by relaxing the tension on the lines a little,
  - juerg replied il y a 10 ans et 5 mois
    
    Hi Mats
    Can’t really see why you want to modify the pully. Put your servo to middle position and add the pully with an offset to the closing position that will account for the different distances for opening and closing. The use the mapping feature of mrl to adjust the overall distance for your servo in use?

Hi Richard! You have to buy 2 Nervo Boards, one or the right side and one for the left side. You would have free outputs in one of the Nervo Boards (because the InMoov for example only have one head) so you can use them in the future to add new moving parts to the InMoov.
