On the 8 picture “Make sure the bracket bottom is at MAXIMUM 4.5 cm (1.77”) from the bottom frame. It should be between 4 cm (1.57") and 4.5 cm (1.77"). Tighten the 2 bolts and make sure that the bracket is perfectly horizontal."
BUT on the 16 picture you can see that the motor is not on the same place.
For me the position of the motor was an issue as this raises the z-limit switch such that it interferes with the home position setting. At the maximum height the z-carriage hits the switch. As I discovered this when calibrating the printer, the easiest solution was to lower the horizontal extruder bar by 5mm, therefore I suggest the 4cm figure is the maximum value when starting from scratch. The microswitch cannot be spaced further away as the screw is not long enough to add another washer.
