Screw joints of Bracchio have become too loose

Hello,

I guess I need to replace some components of my Arduino Bracchio, as some of the screw joints have worn out so much that they do no longer maintain stability of the whole Bracchio, causing the arm links to droop limply.

This concerns especially the screw joints that maintain the stability of the servo motors M3 and M4. For some reason I cannot upload a file in this post, so I cannot show a picture.
Having dismounted the arm piece I can see that the screw joint is directly connected to the servo motor, which is why I guess that the only possible way would be to buy now servo motors.
What would you suggest?

Best,
Arduino-Nutzer

To post images etc you need trust level 1, you can get there by:

  • Entering at least 5 topics
  • Reading at least 30 posts
  • Spend a total of 10 minutes reading posts

Users at trust level 1 can…

  • Use all core Discourse functions; all new user restrictions are removed
  • Send PMs
  • Upload images and attachments

Are these requirements AND-ed or OR-ed? :grin:

ANDed

I was just awarded trust level 1, but still cannot upload pictures.

I get a notification saying "Sorry, an error has occured" all the time.

I believe that there is a batch process in the forum software that runs periodically to update user privileges but I don't know how often it runs

Are you trying to attach images to a post or paste them into a post ?

I am trying to upload an image using the file uploading function.

Just copy the picture and paste it into a post instead of uploading it

The result is exactly the same.

However, we can do without the pictures, they are not that revelatory anyway, I guess. My description should suffice to answer this question. The screw joints are screwed for the servo motors M3 and M4, and they are attached to these servo motors. That is, a slight burden on any of these screw joints causes the arm link to droop. Now I am simply looking for a cheap but satisfactory option to make good the damage.
