+==== Z axis stabilization ====
+one of the structurally weakest point of the Tevo is the off-center Z-axis leadscrew that is hanging by the flex-coupling of the servo.. there are two solutions to this problem, one is to mount the servo at the bottom and then have the Y-axis push down on it, the other is to add a support at the bottom which will hold the weight of the y-axis so that it is not hanging on the flex coupling.
+I decided to go with the support, as it seemed more convenient to implment

 ===== Firmware Setup =====
 Since I have the Auto Level option I had to dig into how to calibrate that thing right away as the auto homing will cause the Z axis to crash into the printing bed with the standard firmware configuration.
