IPA/Windex don’t remove
sugar residue on the sheet)

the sheet. Removing it could
be extremely difficult

Calibration values might be slightly
different for different steel print sheets
because the
coating thickness varies. If you just switched the steel sheets,
visually inspect the quality of
the first layer and adjust the nozzle height
accordingly with Live Adjust Z when
switching
between different types of steel sheets.
Consumable parts,
such as PEI sheets (smooth, textured, etc.)
are not covered by our warranty
because the coatings are designed to diminish over time unless failure has occurred due to a
defect in materials or workmanship. Cosmetic damage, including but not limited to scratches,
dents, cracks or other cosmetic damage is also not covered by the warranty. Only sheets that are
defective on arrival are covered by warranty.
The surface does not have to be cleaned before every print! It is just important to
not touch the
steel sheet with your hands or dirty tools.
All original print surfaces by Prusa Research are coated from both sides
