Hi,
you are quite right. However let me explain please. 10cm more of rail on both sides+10cm more of screw+10cm more of steel profile=no more than 60 euro, which is irrelevant in this build. If we look into KG , they are 5-6 kg more on the gantry
However an ATC is very expensive. And is quite necessary for 3D jobs. Should the need arise to upgrade, for the mere cost of 2 more short supported rails and bearings+another chinese spindle i can mount double Z axis with minor modifications and most importantly without compromising the work dimensions. One spindle will rough the other will detail and finish.
I mean, there also some other points of the design that are done with some things in mind. Its not a general hobby machine.
