Greetings all. Just started building mine and when I installed the antibacklash but the bag had a extra nut and what looks like a long set screw in it. The video did not reference these parts. Can someone point me in the right direction? Thanks
These are for the anti-backlash nut on the Z axis. The bolt screws into the hole on the top of the anti-backlash nut and forces the slot to open. By increasing the distance between the two parts of the nut you can correct for any play (backlash) in the leadscrew. The nut is to lock the screw in place once you have adjusted it Alex. PS you won't need to adjust it much - just enough so that both halves of the nut are pressing against the leadscrew thread. Too much and it will be stiff and the nut will wear more quickly. You will need to adjust it in future as the nut wears.
