To change the hotend, follow the instructions below.
1.
In the
ADVANCED
menu, choose the
HOTEND CHANGE
option and choose the hotend you want to change. You can choose
T0 hotend (Model Material), T1 hotend (Support Material) or both hotends (Both Tools):
a)
if the given hotend still contains filament, the filament unloading manager will be first started (see chapter III, point
4.2),
b)
prepare a new hotend and enter the value of the Delta T temperature correction factor which is engraved on the
hotend (if there is no engraved factor, enter the default value = 1)
c)
wait until the hotend temperature drops below 50
o
C,
d)
switch the printer off and disconnect the power lead.
2.
Put protective gloves on.
3.
Remove the front casing of the module (fig. 51) by pulling it towards you.
4.
Disconnect the bowden tube from the hotend (fig. 52):
a)
slide the C-shaped lock out (fig. 52, step 1),
b)
press the connector lock (fig. 52, step 2) and simultaneously slide out the bowden tube (fig. 52, step 3).
5.
With one hand, gently bend the stopper to the left (in the case of T0 hotend) or to the right (in the case of T1 hotend)
–
in
fig. 53, marked in green. At the same time, press fully and hold the PUSH key (fig. 53, red colour) and push the hotend up
while holding it from the bottom with your hand (fig. 53, yellow colour).
Make sure that the hotend does not fall on the
ceramic heatbed under its own weight.
6.
Take the previously prepared new hotend:
Gently bend the stopper and simultaneously press fully and hold the PUSH key. Insert the hotend into the clamping ring until
resistance is felt and release the PUSH key and the stopper. When inserting the hotend, make sure it is set correctly
–
the
contacts should be directed outwards and the horizontal groove should be directed towards the user (fig. 54). Next, slide the
bowden tube into the hotend as shown in fig. 52. Properly installed short bowden tube will be visible in the hole in the hotend
guiding sleeve (fig. 40).
ATTENTION:
Be especially careful when inserting the hotend. To avoid bending the contacts, the hotend must be
kept in vertical position. If the contacts are damaged or the hotend is incorrectly installed, the "DEF" error (no signal
from the temperature sensors) will be displayed in the temperature indication field after switching the printer on.
7.
The hotend change procedure has been completed. Now you can switch on the power supply, start the printer and go to
the material loading manager (chapter III, point 4.1)
ATTENTION:
after each hotend change, perform the calibration of offsets along X,Y and Z axes again (chapter VIII, point 2.2).
First perform the calibration of offset along Z axis and then along X and Y axes.
