Applying A New Layer Of Protective Kapton Sheet To Your Build Plate - CraftBot CB4 FLOW Series User Manual

13. Applying a new layer of protective kapton sheet to your build plate

Build plate Kapton sheets get worn out in time or can be damaged by the
nozzle due to incorrect levelling or removing the printed models. Reapplying a new
Kapton sheet is essential to maximize print qualities if the old one has issues/
damages. To reapply a new Kapton sheet, take the build plate out of the machine
and remove the old sheet by striping it off of the flexible metal plate. Clean the
surface of the plate with acetone.
Remove the protective plastic backing sheet (keep this safe for use later)
from the new Kapton sheet. in order to get to the sticky side. Apply some window
cleaning liquid onto the plate and the sticky side of the sheet to help you to correctly
the position the sheet on the build plate. Align the Kapton to the front side of the
plate (the edge closest to the screws) on the corner. Once the positioning is correct,
squeeze out the access liquid from between the plate and the sheet with a thin but
solid object, like a used credit card. Place the protective sheet (which was removed
in the beginning) on top the new Kapton to prevent scratches and damages during
this process.
Start from the centre of the plate and move horizontally and vertically. Once
all the liquid has been squeezed out and the sheet is applied properly, put the plate
somewhere to dry. Allow the sticky part to rest for a day before using.
