Thank you! :)

On 3D card you'll find bundled 3D models and calibration gcode you will use after the assembly.

You didn't follow the assembly exactly - top nut in extruder cover needs to be pushed all the way down!

Thanks... Fixed :)

You really have to use M3x18, with second M3x25 you'll make the assembly impossible or you'll destroy the printed part.

We updated the printed parts so the holes should be always the right size from now. Sorry for that.

We added note... Do not cut any excess of the belt, it should be evenly distributed on both sides as shown in the picture.

Please look into your spare bag, there should be one or two as spares.

Thanks. We'll try to modify this part or drill it.

It should be as on the picture. We'll update the text description. Thank you.
