Fun factor available - but also clear weaknesses

The assembly is not so easy - you can easily make something wrong or broken (eg with the soldering iron the belt burn). The order in which instructions are partially not quite perfect. Overall, I no major mistakes two full days at approx 8h needed.

Some parts are poorly finished, you have to partly re-drill holes, parts deburring, ..

The screws for the x / y / z-stops are in principle not a bad idea, but their holders too wobbly. Here I would print a more stable construction immediately after construction, especially for the z-axis.

The heating plate is hard to get completely flat. Possibly it helps to loosen the fastening screws, so they is not stretched. For smaller parts should make the adjustment of the z-stop just above the middle of the plate, where the part is printed and not at the far corner.

The printing results are in perfect alignment then been acceptable, but of course you have to perform various tests and experience until everything fits.
