    I am not sure what I am missing here.  The build I instructions say when to use aluminum coupler vs the pinecones for the z axis.  I bought the kit and have no idea if it is all thread or threaded rod?  I used the pinecones but how do I know the difference?



    If you bought the kit within the last 8 moths or so it comes with the aluminum coupler and a T8 leadscrew. There are pictures of both on the Z axis assembly page so you can see what the difference is. The aluminum coupler is a metal spring looking widget, and the pineapple coupler is plastic and has an odd shape to it. The T8 leadscrew has far fewer threads on it and is polished the 5/16 allthread is standard bolt material from the hardware store.

    I know what the coupler and the coupler was i closed also, it jua  wasn’ clear what screw I got.  I looked at the picture, just asking a question to make sure.  I didn’ think it was clear.  I threaded it into the pineapple coupler with minimal effort but I couldn’ figure out why both were included in the kit.
