3. Check the distance between the nozzle and the platform. If the platform is currently at
121mm and appears to be about 12mm away from the nozzle, change the number in the
text box to by 9mm to
130 and click the To button. Use small increments from there when
calibrating the nozzle to avoid striking the platform into the nozzle.
4. Once you are about 1mm away from the nozzle, increase the number in the text box by
0.1mm increments and click the To button. Repeat until you get 0.2mm from the nozzle.
TIP: An easy way to check the
distance between the nozzle
and platform is to fold a piece of
paper in two, which will be
about 0.2mm thick. Use this
as a spacer to gauge the
distance between the nozzle
and platform.
5. Once you have the platform within
0.2mm of the nozzle, click the Set
Nozzle Height button to save the
current nozzle height.
6. Check the nozzle height at all four corners of the platform. Repeat the Platform Leveling
and Nozzle Height Calibration processes if needed.
You may need to recalibrate the nozzle height after moving the printer or changing the
printing platform if the models are not adhering to the platform properly or are warping.
TIP: If the platform contacts the nozzle while making height adjustments, it is good practice to
re-initialize the printer and before undertaking any other operations.
Platform Level Calibration
This process is not intended to replace manually leveling the platform. It should only be
used if your print surface itself cannot be leveled due to warping or an inconsistent
thickness.
If the platform surface cannot be leveled after performing the leveling and nozzle height calibration,
there is a utility in the Afinia software that allows you to adjust the printing of the raft to level the
model printing layers by dividing the print platform into several zones and entering adjustments for
each.
Note that this will only affect printing when using a raft; if
you are printing raftless, this utility will not affect print
leveling.
Select Platform Calibrate from the 3D Print menu to
open the utility.
First, find the highest of the 9 points on the platform.
Click the button labeled 5 to move the nozzle to the
center of the platform. Use the Up button to raise the
platform; holding the button down will move the platform
steadily, while single clicks can be used to fine-tune the
platform height.
Raise the platform until the platform is just touching the
nozzle and note the current height.
Next, click the Down button a few times to lower the
platform then click the 1 button to check the platform at
the back left corner.
