Installing the hotend
Loosen the two (2x) screws and remove the cover (fig. 1 and 2).
Loosen the clamp block of the heatsink.
Loosen the screws of the extruder.
Unplug the terminal of heater and NTC.
Insert the 400 °C hotend. Pay attention to the installation direction: the
heater and temperature sensor must face towards the rear (see fig. 8)
Fix the locating slot of the extruder to the locating screw.
Fasten the extruder screw.
Push the hotend to the top (fig. 11) and fasten the clamp block of the
heatsink (fig. 12)
Fasten the screws and install the cover (fig. 13 and 14)
Loosen the screws of the bottom cover
Remove the bottom cover.
Disconnect the terminal plug E-TMP(NTC) (fig. 17 and 18).
Connect the terminal plug < E-TMP(KTC)> to the disconnected terminal
(see fig. 18)
Attach the cover.
Calibrating the extruder
After installing the hotend, you must re-calibrate the distance between the sensor and nozzle.
- Download the configuration file config_KTC.gcode from www.conrad.com/downloads.
- Load the file into the printer firmware.
- Perform the Z-offset calibration. Follow the steps 1 to 19 shown below.
Important:
If you install the 260 °C hotend again, load the configuration file
config_NTC.gcode into the printer firmware. You can download the file from
www.conrad.com/downloads. Perform the
Z-offset calibration.
Loosen the sensor screws. Make sure the sensor can move up and down freely
Put the black Z-offset calibration tool under the sensor and nozzle to
calibrate the height.
Make sure the sensor sits approx. 1.5 mm higher than the nozzle, then fasten
the screws.
Insert the print bed and magnetic mat (fig. 5 and 6).
Enter the menu and go to TOOLS > Preheating
Wait until the temperature of the print bed reaches the pre-set value (fig.
9 and 10)
Go to Manual and press the “Home” icon. The extruder will move to the zero
position.
Turn on Z-offset calibration. Slide an A4 sheet of paper between the nozzle
and the print bed.
Select 0.1 mm (important!). While sliding the paper back and forth, use the
controls to adjust the distance between the nozzle and print bed until you
notice light resistance. Save the Z-offset with .
Continue with Confirm.
Go to TOOLS > Leveling.
Let the auto-levelling function run to complete the Z-offset calibration.
