Kuhling&Kuhling RepRap Industrial User manual

Operating manual
If your RepRap Industrial 3D printer is of hardware revision 1.0.0 and has not been updated, you are
probably still running RepRapOnRails version 1.0.5.
Clicking here will redirect you to the respective manual.
The high-resolution 10“-TFT touchscreen mounted at the front panel enables direct operation of the
RepRap Industrial.
This manual describes the initial commissioning of the 3D printer after installation, the operation via
the RepRapOnRails operating software and the all manual operating tasks that must be performed
during normal day-today use.

profiles for the extruders and the print bed and
build chamber more directly which simplifies
preheating and priming according to current
needs.
Setup offers the operating wizards for guided
day-to-day functions.
More advanced features like program-
independent operation of the axes have been
moved to the Expert control screen which now
also provides direct setting of the extruder
temperatures and test extrusion.
The Log menu provides the history of machine
code input and output as well as the keyboard
for direct input of operating instructions.
The following paragraphs provide detailed
information of the software's operating screens
and explain the specific functions.
Additional information for the preparation of
print jobs can be found in Tips and tricks and the
manual of the slicing software.
Starting the 3D printer
There are two possible states from which to start the 3D printer: “switched off” and in “standby”.
Either way starting the 3D printer is a one-button-only procedure. After the boot sequence the
operating screen starts with the Print screen in IDLE mode.
Switching on
If the 3D printer is switched off via the main
switch at the rear cover (position <0>) toggle
the switch to <I> (ON).
The 3D printer will boot automatically.
It may take a few minutes until the touchscreen
has fully loaded the operating screen - wait
patiently without interfering.
The first screen will be the Print screen with the
(empty) print-job queue and the top-left status
message displaying Idle.
Waking from standby
If the 3D printer has only been shut down via the
touchscreen and set into standby mode (see

section Print screen), press the wake button at
the front cover. The light ring of the button lights
up and the 3D printer boots automatically.
Waking the 3D printer from standby.
[Print] screen
After starting the 3D printer the Print screen will
appear as the start-up screen. Here you activate
the 3D printer and start the print jobs previously
uploaded to the queue via the web interface.

Pause function
The pause function was built in for the case that
a print job needs to be interrupted and later
resumed for other reasons than “out-of-filament”
(see below).
After tapping the [Pause Print] button, the
printer keeps printing until the cache is empty.
This may take a few minutes, according to the
complexity of the current g-code. Afterwards,
the print bed is lowered into its home position,
the extruders are turned off and the print head
moves to the maintenance position.
Interrupting the print with the pause function.

Now you have access to the Expert Controls and
some of the Setup functions to adjust whatever
might be necessary.
To continue printing tap [Resume Print]
(replaced [Pause Print]). Print bed and extruder
head move to their last position and after re-
heating the extruders the print seamlessly
continues.
Continuing the print after pause.
Finishing a print job
There are two ways to finish a print job:
automatic finish after completion or abortion by
the operator.
After regularly completing a print job all axes are
moved to their home position and the extruder
heating resistors are switched off.
If you need to abort a print job because the
outcome does not meet expectations for
example or mechanical problems appear during
the print, tap the [Abort Print] button. The
system will then print the last G-code
information from cash and move the print table
and the extruder head to their home positions
afterwards.
Either way, the 3D printer returns to idle mode
and displays a status message and a request
how you wish to continue. Simply tap the
respective button on the screen to proceed.
After standstill of all drives you can remove the
print bed and take off the model.

Switching off the 3D printer
NOTICE
Switch off the 3D printer via the power button without turning it into standby may cause damage of
the heating elements and neighboring components due to residual heat.

The cool-down performed during shut-down ensures that the fans are only switched off after the
heating elements could shed all residual heat.
For switching the RepRap Industrial into standby
tap the shut-down button. The system will then
perform the cool-down sequence for safety
reasons before deactivating the preheating and
the build chamber.
The 3D Printer is in standby mode when:
the screen turns black,
the illuminated ring of the wake button
dims,
the build chamber lighting switches off.
To wake the machine from standby see Starting
the 3D printer.
Always use this button for regular shutdown.
For completely shutting down the 3D printer,
perform the procedure described above and set
the main switch at the rear cover to <0> (OFF)
afterwards. The 3D printer is now powered off
and the green status indicators of the limit
switches darken.
To reactivate the 3D printer see Starting the 3D
printer.
INFO
For day-to-day use, the power
supply should stay connected to
mains power (main switch in
position <I> (ON).
Emergency stop
NOTICE
The emergency stop function does not provide a cool down sequence. Do not use the emergency
stop button to abort current print jobs, as this may lead to damage of the 3D printer due to
uncontrolled heat accumulation. Do not use the main switch as an emergency stop button. You risk
loosing or corrupting data.
When the emergency stop is triggered:
The microcontroller board is reset, all
movement of the axes stops, lights,
heaters and fans are turned off. The status
indicator displays Emergency Stop! .
After a few seconds the microcontroller
returns to Idle state.
Status display after triggering the emergency
stop. The 3D printer returns to IDLE state after a
short time. The emergency stop is written into
the log-file.

The 3D printer now is in a safe state for troubleshooting.
For repairing any defects of the electronic equipment or major mechanical damages shut down
the 3D printer completely:
Open the Print screen.
Shut down the 3D printer by tapping the [Shutdown] button and switching off the main switch
(<0> position) after the shutdown procedure has been finished.
NOTICE
Before restarting or reactivating the 3D printer:
Make sure that the axes are in no collision position.
Make sure that the reason for the emergency stop has been detected and fixed, before
resuming production.
After troubleshooting or if the reason for the emergency stop was minor and you want to continue
production:
Remove the print bed from the build chamber and replace or clean it before further use.
Restart the 3D printer (if necessary).
Open the Print screen.
Switch on the build chamber. The 3D printer will run the homing routine.
You can now resume normal operation.
[Configuration] screen
The Configuration menu is a new feature that
enables you to preselect material-specific
temperature profiles for each extruder and, in
combination, the print bed/build chamber. The
latter was developed to make preheating and
leveling more precise with regard to different
material settings. The according profiles can be
set up at the web interface setup menu.

The selected profiles are displayed in the footer

temperature, both values are highlighted red.
When displayed gray, the temperature value is
either not set or currently not triggered.
The selected profiles are displayed in the footer
of the GUI on every screen.
INFO
Observe that the temperature
shown in the footer is measured at
the hot end heater and may be 5 -
10 °C lower at the nozzle tip.
See section Extrusion temperature
in the knowledgebase for
information on finding the suitable
extrusion temperature.
When no filament profile is
activated for an extruder, the
default temperature is 180 °C.

Creating profiles via the web interface
During a print job all necessary temperature data are provided by the respective G-code. For priming
the extruders outside a print job the temperature setting required for extruding a material is provided
by the Filament profiles.
Similarly, precise print bed leveling needs defined bed and chamber temperatures according to the
printed material before a G-code is executed. These settings are provided by the Chamber/Bed
Preheating Profiles.
To create a filament profile open the web
interface of your 3D printer, choose the Setup
menu and:
Select Filament Profiles and click [Add1.
