Materials and Tools
NoteThe ball bearings will be epoxied to one end of the aluminum tubes at a time so start this assembly relatively early in the build to allow time for the epoxy to cure.
There are six connecting rods that connect the end effector to the printer via magnetic ball joints. Each rod consists of an aluminum tube with steel ball bearings epoxied to each end.
- Perform a practice run prior to mixing the epoxy: Push the tubes into the holder so that the tube axis is vertical. Place a ball bearing on top of each tube and ensure that the tube and ball bearing remain relatively stationary. (Ball bearings must not fall off the tube.) Don't start mixing the epoxy until you are confident that you can finish the process before it sets.
- Remove all the tubes from the stand and shake out grains of the holding medium.
- Keep the excess mixed epoxy at-hand to test set (usually about 15 minutes for quick-set epoxies). Wait until the epoxy has thoroughly set or fully cured before disturbing the rods. Repeat the process on the opposite end of the rods. Make sure all the grains of holding medium are shaken out of the tubes before proceeding to epoxy the remaining ball bearings on them.
