Tronxy 5 second Z axis

Original construction of cheap chinese printer tronxy 5 use only 1 z axis. this can create big vibration even with standard printing speeds. Second z axis completely removes this problem.

In fact, this second axis can by used as replacement for original axis as well. I have removed original aluminium rods from table and used cheap aluminium profile 20x20x2mm and 40x3mm.
You will need simple tools for drilling and cutting aluminium parts. including drills up to 10mm.
Some parts you can buy
