Great product, very complete: for all tiny screws and bits, there were spare parts, so never missing a piece. Mounting is a bit fiddly, but fairly straightforward when you get the hang of the tiny screws. Take your time to properly align, e.g. table carriers 70 mm away from the sides, paralleling the table with the front and rear frame, etc. It may look that it does not work directly, but it does: the stepper motors make tiny steps in the factory default mode.
