I have just bought a labists X1 (https://labists.com/products/mini-3d-printer-labists-x1) (£30 I couldn't resist) as my first adventure in to 3d printing. The first few prints went fine but the last couple have a weird issue. The bottom layers print fine but the top few (10/20/not sure) print offset by 5-8mm. So it prints exactly the right thing but in the wrong place.One print was one I downloaded from Thingverse and another I created myself. Using Cura to slice and create gcode as recommended in the instructions but the same happened when I used slic3r.Not sure what info to give but any help or pointers would be greatly received. It is under guarantee so if it's a printer issue that's fine, but some items print perfectly so doesn't seem to be.
