MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Pictures superimpose screw-to-screw, rod-to-rod, label-to-label. The ONLY difference is WHITE Z-axis supports, mine being black.
My idea is that as it happens over and over again with the sizes of the power supply box the printers may have small lot-to-lot differences, sometimes even improvements, which are not reported in documentation. Anet already changed A8 specs "on the fly" in the past, this same forum is full of "variations on A8 Theme". Low-end DIY printers are NOT a world where you can demand strict industrial standards - they are beautiful for this, by the way.
No reason to turn aggressive or insulting, I think.
Peace! and thanks for counseling.
