On this page I have collected my experience with the TwoTrees Sapphire Plus V1.1 3D printer. Bought in juli 2021 for 420 Euro. I found them now on the internet for 370 Euro. This printer has the Mks Robin nano V1.2 board with 5 TMC2225 drivers and has a dual Z-axis each with motor but coupled via a belt.
This page is not about how to assemble the Sapphire Plus. "Aurora Tech" and "Just Vlad" already have done that perfectly on Youtube. This page is about the problems I had and how I solved them.
The Sapphire Plus is not a 3D printer kit that requires a "one" hour of assembly and then prints perfectly ("out-of-the-box"). If you want that then better buy a Creality. Assuming you don't make any mistakes and this is not your first 3D printer an 4-8 hour build is do-able but don't be suprised if it takes up to 60 hours with all kinds of suprices. Just read this page. Careful and accurate assembly of each step is necessary. Then finally do some testing using the printer's menu (moving, homing, heating) to check that everything works.
