Leadscrews for the RailCore II 3D printer?
TR8X4 leadscrew 400 mm are the standard for RailCore II ZL 3D printer. Combined with a 0.9 stepper these give you 0.01mm full steps. For the RailCore II ZLT 3D printer the TR8X4 leadscrew 700 mm long is the recommended choice. A lot of testing on the print quality in the Railcore community has resulted in the recommendation of using TR8X4 with 0.9 steppers instead of using TR8X2 with 0.9 or 1.8 steppers.

Leadscrews for the Jubilee Toolchanger 3D printer?
The default choice of leadscrews for the Jubilee toolchanger 3D printer is TR8x2 leadscrews 375 mm long. It is possible to use T8x4 leadscrews 375 mm long. These can effectively double the Z movement speed. This can be very useful for non-printing applications where the bed experiences lots of height changes. When run with 0.9 mm stepper motor, they do not accumulate error in the case where the Z axis moves in full-step increments. (For more on error accumulation with particular leadscrew/motor configurations, see the this calculator.)
