M3x8mm Screws Not Correct

Post by mosterkamp » Fri Apr 07, 2017 9:14 am

The M3x8mm screws that came with my Rostock 301 printer have the wrong thread pitch. They do not fit in the rod-end bearing holders. After 15 emails, Geeetech sent me 20 new screws. Of the 20, only 12 were correct. The other 8 were too wide. Did anyone else have the same quality assurance issues?

I had the same issue. I brute forced them in. They won't come loose that for sure.

I had exactly the same problem. Luckily, I had an M3 thread cutter, so I fixed it myself.
I wish that was the bigest problem with this crappy printer! It's been over two months that I own it, and still couldn't print anything.

Many people here had same problem.
I do not even remember how I straighten out the situation, it just disappeared with time I guess, like 1-3 days, then everything went right.
