I designed this Z Lock M8 full threaded for MPCNC IE because with the stock IE_z_nut_lock_13 mm always occurred the downward movement of the 13 mm nut even if I strong tightened the fixing screws but when using the CNC the nut will never remained in the clamping position with the consequent upward vertical loosening of the Z tower. For better and smooth running of the 8 mm Z rod inside this full threaded Z lock I recommend to heat approximately 70/80 degrees Celsius a screw M8X40 compatible with the thread of the rod Z to screw and unscrew it several times into the thread of Z Lock just printed and still warm, in this way the internal thread of the Z Lock will fit better the Z threaded rod of the central MPCNC tower to solve the listed issues. After mounting you can put on the thread of the Z rod a few drops of oil which will help a more easy sliding.
