 You can adjust the tension of the belt by turning it clockwise for increasing the tension and turning it counter-clockwise for decreasing it.  
 **As two belts are given, make sure to adjust the tension of them as equal as possible!**

 ## Z-Axis
 The z-axis is driven by two lead screws which are connected to each other with a timingbelt at the very top.  
 Both lead screws are attached and driven by z-axis motors.

 At the bottom part of the lead screw there's a 10mm long unthreaded part and at the top this part is ~23mm long, the outer diameter of these shafts is 5mm. Means, you can *not* just get one of those typical lead screws which have the thread going all along the whole length of the rod if you need a replacement!
