LEVELING THE HEATED
PRINT BED
It cannot be stressed enough that levelling the printer bed correctly is essential to achieve good adhesion between
the printer bed and the first layer of all your 3D prints
.
Only
VERY LIGHT
contact is required between the tip of the
nozzle
and the printer bed, ideally
NO
"gap" should be present. However, a sheet of standard 80 gram printer paper
can be used to gauge when the nozzle is very close to the printer bed during adjustment, by feeling friction on the
paper as the nozzle starts to squeeze the paper against the printer bed.
Although so called 'automatic printer bed levelling' could be easily installed on this machine, only manual printer bed
levelling has been installed on this machine. This is much more consistent and accurate and after a little practice,
proves a far better levelling method than any 'automatic' alternatives. Future additional Bed Levelling is only required
if the first print layer appears too close (nozzle scraping on the print bed) or too far away (first print layer does not
adhere sufficiently) from the print bed.
It is good practice to level the Printer Bed after loading the filament with the Nozzle and Heated Bed at printing
temperature, before each print. This allows for the Nozzle to be clear of hardened filament - allowing accurate
judgement of light contact between Nozzle and Printer Bed.
It also allows, once bed levelling is complete, to proceed straight to printing without the risk of the interfering with
the levelled bed.
Experience in this procedure will be gained quickly, through practice.
There are several ways to ensure that the bed is level and ready to print.
Note:
Before attempting to level the printer bed using method
a.
or
b.
(page 10) manually rotate the Bed Lead Screw
clockwise until the Nozzle lightly touches the printer bed. At this position the lowest LED on the Hot End PCB (Z home
limit switch indicator) should be illuminated. If it is not illuminated, turn all the thumb screws (x4, located at each
corner of the headed print bed) one full turn anticlockwise (to lower printer bed) and repeat test from '
Note:'
(above).
Continue this procedure until the lowest LED on the hot end PCB illuminates when the nozzle is just touching the bed.
