z-axis coupler and threaded rod

[zhangxueyou]

I did email the support, about twice for my lcd and this coupler, do they really get my email?

I am sorry, but it's really hard to answer this question.

Same issue here.

After struggling with the printer for 7 months after the purchase, I just give up. It doesn't work because the issue with the threaded rods.

I've read hundreds of comments on this forum (and others) and followed all instructions and recommendations with no success. The Z-axis won't move and IMO the problem is that the rods are thicker than they are supposed to be, so they don't fit the couplers and get stuck on the upper holes (the acrylic cap).

What can I do to fix the problem?

What's the diameter?
If they really can not fit the Z top cover, please contact the sales.
