Thread a lead screw through the anti-backlash block behind the Y-gantry (for the 12x30 this will match the length
of the rail). The ends of the lead screw should be able to rest in the big holes on both steel end feet.
If you find that it’s difficult to thread on, ensure you’re bringing in the lead screw from the right direction
(pictured). If you remember, the anti-backlash nuts have a little arm on them and you can also try reaching
between the steel Y-gantry and the rail to reach the nut and wiggle this arm to assist in threading the lead screw
on. Worst case, remove an end foot and roll the Y-gantry back off to check the anti-backlash nut for burrs and
debris and try threading on the lead screw again. You can also try swapping to the spare block if needed.
