Lead Screw Taz 4

I have a Taz 3 and a Taz 4.
I am rebuilding my Taz 3 to conform more to the Taz 4 Hardware.
I have been looking in the documentation folders and I know I found it once but can’t find it again.
I am looking for the Drawing for the Lead Screw for the Taz 4 that is about 400 or so mm long and 10mm thick with a 5mm keyed shaft on the end.
I just need the drawing to see the specs, I will also be needing the drawing for the corresponding nylon nut that attaches to the x carriage.

Can I Please ask for a linky many thanks in advance!

Here’s the leadscrew info. Diagrams are at the link.

Download.lulzbot.com is where the rest of the documentation is.

Ihave now found the proper lead screws and working on getting the plastic parts printed and upgraded on my taz 3.


I-t-w.com has the metal x end plates if you need them, also the hexagon parts and pei sheets to take it to a taz 5 instead of a 4.

We have “manufacturer seconds” OE Lead screws, which we have a machinist check and bin by runout. Some of the .003 and under are much straighter than even .003! https://itworks3d.com/product/lulzbot-taz-45-z-axis-lead-screw-threaded-rod/
