⬢Besides the X-axis, please prepare for the following step:
⬢Smooth rod 320 mm (2x)
WARNING: be very careful while installing the X-axis on the trapezoidal lead screws. The process should be smooth, otherwise you might damage the thread inside the plastic nut. Reseat the axis if necessary.
⬢Carefully slide the X-axis on the trapezoidal lead screws. By rotating both screws simultaneously let the X-axis slide until both trapezoidal lead screws are visible. If you feel any significant resistance, try to reseat the axis first.
⬢Make sure the top smooth rod of the X-axis and the lower edge of the frame are parallel.
⬢NOW, PLEASE BE VERY CAREFUL! Gently insert the remaining smooth rods through the bearings on the X-axis all the way down into printed parts, do not apply too much force and do not tilt the rod!
In case you manage to push out balls from the bearings, please count them. One or two balls are ok, if there are more of them, please consider ordering new bearings
