Z Lock M8 Threaded for MPCNC IE

thingiverse

I designed this Z Lock M8 full threaded specifically for the MPCNC IE because the stock IE_z_nut_lock_13mm often led to a downward movement of the 13mm nut, even when I tightened the fixing screws firmly. However, using this new lock on the CNC ensured that the nut would stay clamped in position and never loosen vertically. To ensure smooth running of the 8mm Z rod within this full threaded Z lock, I recommend heating an M8x40 screw to around 70-80 degrees Celsius. Then, use the screw to tighten it several times into the still-warm thread of the Z Lock. This will help fit the internal thread of the Z Lock snugly onto the central MPCNC tower's threaded rod and resolve any listed issues. Once mounted, a few drops of oil on the thread of the Z rod can help facilitate smooth sliding motion.
