Print Bed Leveling / Calibration - Mass Portal Pharaoh XD Series User Manual

Print Bed Leveling / Calibration

The print bed on Mass Portal printers is held in place with three
thumbscrews. The slant and height of the print bed can be
adjusted by turning the thumbscrews. As a general rule, the print
bed should not be slanted — the thumbscrews are used to keep
it level. Normally the thumbscrews would not need adjusting by
more than 1mm or 2mm at max.
Mass Portal printers have a bulit in sensor, that can measure and
adjust to the print bed accordingly. This is done to ensure that
first layer of prints is correctly printed — that the nozzle is not too
high (material not sticking to the print bed) or too low (nozzle too
close to the print bed, material "smeared" into print bed).
TIP The print bed can be leveled
manually by adjusting the three
thumbscrews that hold the glass
print bed. This can be done after
calibration, if minor adjustments
are needed.
WARNING The thumbscrews
MUST NOT be screwed in till
lowest possible position, but it is
normal for the screw to stick up
a little bit (see picture). The print
bed must have some play, so the
springs below it can compress — you must be able to move print
bed down a bit when pressing on it. This is a safety measure in
case if the print head moves too low.
TIP It is not necessary to use calibrate the print bed before each
print, or even regularly. If the first layer of the print is correctly
printing, there is no need to recalibrate the printer. The printer
can go for a long time before needing to be recalibrated.
Calibration Process
Please go to the chapter about 'Printer Setup' (Page 8) to see
the calibraion process for yout printer.
TIP The sensor
plates in the print
bed are not attached,
so it is normal for the
sensor plates in print
bed to move.
WARNING To
ensure correct
measurements, the
calibration process
works ONLY when
the printer is at room
temperature. If you
attempt using the
auto calibration when
the printer is hot,
you'll see a warning
and the calibration
will not be done.
WARNING The
print head will
move down when
calibrating to make
the measurements.
Make sure there are
no objects, hands,
or previous prints on
the print bed before
performing the
calibration process,
otherwise the print
head can damage
them.
