AnyCubic Prusa i3 User manual

Assembly tips:
To assemble the printer efficiently, it is suggested to put all parts on a flat surface (i.e. a table).
You may tear off the kraft from the acrylic sheets before get started.
Avoid tightening the screws excessively, otherwise the acrylic sheets may be broken.
This manual takes the black acrylic sheets for example, if you have chosen the transparent ones, the
assembly and setup are the same.
The firmware has been pre-uploaded to the ANYCUBIC board, you only have to level the print
platform and start printing right after the assembly.
We may not notice the upgrade for the printer.
If you have any questions or suggestion, please contact us on [e-mail] or
