plate leveling by loosening a little at a time.
3.
Make sure the Autoleveling sensor is securely attached to the extruder.
4.
Check that the bolts on the bed are fixed with even torque.
5.
Make sure that all coins - 9 in the middle and 4 at the corner - are in normal positions
on the glass plate. (In Autoleveling, the sensor should be at the center of the coin, and
the left and right alignment is important like a checkerboard)
6.
With the bed temperature reaching the target temperature, check that the gap between
the glass plate and the bed remains even.
7.
When measuring Probe, check 3 times if Z axis Align is working properly. (Do this while
the keeping the upper door closed.)
8.
The upper door should be kept closed when Autoleveling.
[When the print keeps falling off the bed]
1.
First refer to the section [General preparation before printing]. Check all items before
moving onto the next step.
2.
While the first layer is printing, check the front door (if necessary, open the top door
within 10 seconds) to see if any of the following (
subsections 2.1 – 2.8
) occur and follow
appropriate troubleshooting instructions below:
-
Only when the first layer is printing, you can open the front door and the upper
door to check the status of printouts or remove unwanted filaments.
-
Do not open the front and upper doors as far as possible from the second layer. The
printout contracts and deformation may occur.
2.1
Filaments are discharged from the air due to a gap between the nozzle and bed
-
Decreasing the layer gap of the first layer improves layer adhesion. During printing,
adjust the thermal offset value at an increment of 0.05 ~ 0.15 mm units. Set the thermal
offset value so that the thickness of the printed material becomes 0.15 ~ 0.2 mm. The
Thermal Offset value adjusts the bed-nozzle spacing by a relative value. (It may be
negative number.) The gap between the nozzle and the bed widens with the increasing
value, and vice versa.
2.2
The lines making up the first layer are falling apart
-
Reduce the Thermal Offset value during printing at an increment of 0.05 mm to ensure
that lines making up the first layer are closer to each other as much as possible
-
When the brim has been printed at least 2 lines, remove it and check preliminarily that
the lines are well stuck together. If the brim is 10 lines or less, the adhesion may
