Assembly Problem - Joint

Anonymous — Mon, 25 Nov 2019 02:03:38 GMT

To Whom it may concern,
Hi, I have some problems with the Joint. I have attached a video that describes the problem. I am trying to assemble the Delta Robot mechanism. It's fine at the first two mechanical arms, but when I tried to assemble the last part, the mistake just happened. I can't figure out what's wrong in the process and don't know how to make it work.
Any advice is appreciated, thank you.

Best Regards, Blake

Try again with Cylinder Joint,

there is an Alignment error somewhere, - that the first 2 sets are okay but last one show a misalign between the two faces of this joint.

Will need the model, for better than a guess.

Might help.....

Thank you for the quick reply.
Here is the 3D model. Really want to know why Revolute Joint can't work, but Cylinder Joint can.
and is there any influence when I using the Cylinder Joint in the last mechanical arm, but Revolute Joint in the first two ?

Thank you for the model, some problems, but might not be for misalignment.

This pic shows same drive leg, with 2 joints, not a good thing, and might cause a lock up when one goes but the other does not,

This pic shows, two plates for the same job, I can not read your labels, but again if you are join to wrong one?

If you say the Cylinder Joint did work, then it is very very tiny misalignment that causes it, It is said that Fusion wants to be too precise, I just know that binding will stop if Cylinder does work.

Might help,.
