Calibration 2
nd
extruder (X, Y-as calibration 2
nd
extruder)
In printing with 2 print heads one could find that the printed objects are not aligned properly. This
means that the alignment of the 2
nd
print head is incorrect. This might happen in installing a new
nozzle or hot end. In this chapter we explain how to align the 2
nd
print head according to the first
head. We are only going to set the X,Y values (offsets) of the 2
nd
head. So the settings of extruder 1
we leave at peace.
Conditions:
- The bed needs to be aligned correctly. (see chapter 9.1)
- The height of both nozzles must be correct in relation to the bed. (see chapter 9.2)
Requirements:
- 2x PLA-filament (Preferably two different colors).
1.
Download the calibration print (O231-01 - Calibration XXL PRO 2) via:
https://www.prodim-
systems.com/en-en/Support/software-downloads.html
(beware: it is a zip file which needs to be unpacked)
2.
Save the downloaded g-code on the SD-card.
3.
Preheat the extruders and the bed to PLA temperature.
Ensure both extruders have reached the set temperature and the hot ends are full with material.
4.
Print the calibration print.
5.
After the print is done move the bed down a little via menu > “Move Z fast”. So you can correctly
view the printed lines.
With the calibration print we can determine how many
mm the 2
nd
print head is misaligned with the 1
st
head.
6.
Check in the x-as which red line is perfectly aligned
with one of the black lines. Count the red stripes
from the middle long black line. Every stripe
represents 0,1 mm. Note this value.
example:
We view the stripes on the big X (x-axis)
The 4th stripe on the right side of the middle long black line is perfect. The print head thus has
to be corrected with 0,1 x 4 = 0,4 mm on the X-axes.
Goal is to get the middle long lines perfectly aligned.
