Best Z axis rod for setup as mill?

Was about to order the T8 leadscrew from the store, but there is a note on the page “Not a good option for the MPCNC, Perfect for the MP3DP. (See the FAQ)” I could not find a note regarding that in the FAQ and the parts kit shows including the T8. Also, same not is on the coupler page. What is the best choice for Z axis for a MPCNC if I plan to use it mainly for milling? Thanks for any advice!

Sorry I’ll fix that. Lots of testing has been done since I wrote that.

I thought that was the case, just making sure. Thanks!
