The new lead screws for all MTW printers offer great performance with built in wobble-isolation. They are super smooth and substantially minimize z axis artifacts.
In addition to their other benefits, these are two-start lead screws, so will provide faster Z movement on the MM2, MiniMax and Create Express. You will need to adjust your firmware steps to 800 steps per mm (Contact our support department if you need help with this).
Unlike our older lead screws, these do require a periodic application of lubricant. We recommend white lithium grease or light machine oil. You can run them dry, however rapid travel moves (such as when doing the ABL routine) will be noisy.
Note these require a printed adapter to work with our printers. They are available as accessory add-ons, or you can download the STLs here:
The lead screws are sold individually. You will need one screw for the Create Express, MiniMax, Fusematic. You will need two for the MM2, MM3, and MTW Create. Please note that for the MM2 you will need to purchase M5 to M5 couplers.
