8. Working principle of the 3D printer
For3Dprint,rstaleisneededthatcontainsthethree-dimensionaldataoftheobjecttobeprinted(acommonformatofsuchaleis,e.g.,
a.stl-le).
Thislecanbeproducedwiththecorrespondingsoftwareorwitha3D-scanner.Therearealsomanyprintinglesonlinethatcanbedown-
loaded to print an object as quickly as possible.
Theactualprintersoftwarehasthetasktorendertheabovethree-dimensionalleintoalethattheprintercanprint.Thisisaleinwhichthe
individualprintlayers,thetemperaturefortheprintingheadorprintingheadsandprintingplate,etc.arespecied.Thelehastheextension
".gcode".
ThisG-CODEprintingleissenttothe3DprintereitherviatheUSBinterfacebythecomputer,oranSDcardwiththeprintingleisputinto
the card reader and the 3D printer is used in standalone operation.
The3DprinterprintsthelelayerforlayeraccordingtotheFFF(FusedFilamentFabrication)/FDM(FusedDepositionModelling)procedure.
Attheactualprint,thelamentmaterialistransportedfromalamentrolltotheprinthead(extruder).Forthedualextruderandtwo-coloured
printing, this is done alterantingly with the two print heads.
Intheextruder,thelamentmaterialismeltedandthenappliedtotheprintingplateviaaneextrudernozzlelayerbylayer.
TheheatedprintingplatemovesintheYandZdirections,theextruderunitmovesintheX-direction.Thus,allprerequisitestoproduceathree-
dimensional object by horizontal application of the present layers are created.
A 3D printer is a highly complex device in which many parameters must be set depending on the printer, printed object and
lamentmaterialused.
Additionally,theadhesionoftheprintedobjectontheprintingplateisinuencedbyprintingplatetemperature,lament
material, shape of the printed object and surface properties of the printing plate.
 Ambienceinuencessuchasdrafts,greaseontheprintingplate,etc.alsoplayaroleinthequalityandadhesionofthe
printed object.
For the above reasons, it is not possible to achieve high-quality print results at once and without previous experiments.
Change the adjustable parameters in small steps to achieve the best printing results for your application. The printing
examplesenclosedontheSDcardprovidereferences,butmustberenedforperfectresultsdependingontheabove
parameters.

11. First commissioning
a)Overviewoftherststeps
Thefollowingoverviewshowstherst,importantstepswiththeRF2000v2.Thisisabriefsummaryofthesubsequentchaptersuntilyourrst
print with the printer.
• Completionofinitialcommissioning.
Some important things are explained to you here that you should do in any case after transport and unpacking. The chapter "Initial Commis-
sioning" also contains important notes on correct setup of the printer and, of course, correct connection, incl. important safety notes.
• Downloadofthesoftware/rmwarepackage.
 Weregularlyprovidenewversionsofthedownloadpackageonourwebsite.Itcontainsthecurrentrmwareandsoftwareaswellascurrent
printing examples.
• Updateofthermwareoftheprinter.
 Beforeyoucontinue,alwayscheckthermwareversionofyourprinterrstandupdatethermwareifnecessary.Errorsarefrequentlyre-
moved here and new functions may be installed.
• Familiariseyourselfwiththegeneraloperationoftheprinter.
Before you are able to sensibly use the printer, become familiar with its operation. We will not only introduce operation via the key pad to you,
butalsobrieyexplainthemenuoftheprinter.
• Executionofthecalibration.
 Calibration(basicsettingoftheZ-limitswitch;settingoftheextruders,executionofaprintingplatescan)isoneofthemostimportantsubjects
of the operating instructions. Only if you have correctly performed calibration will you also achieve a good printout.
• Firstinsertionofthelament.
 Wewillexplaintoyouhowyoucaninsertorexchangeorreplacethelamentcorrectlyandwhatmustbeobservedinthis.
• YourrstprintofanexampleobjectfromtheSDCard.
 WewillleadyoutoyourrstprintoutstepbystepusinganexamplefromtheenclosedSDcard.Alsoobserveournotesattheendofthe
chapter after printing out and the general notes in the chapter below.
Before you start initial commissioning, all transport protections or fuses that have been installed during installation or for
transport must be removed.
Thenisheddevice(singleanddualextruder)hasbluecrepeadhesivetapestucktotheprintingplateinthefactory.Thisimproves
adhesion of the printed object. This special blue adhesive tape can be re-ordered at our shop under Conrad order no. 1093104.
The printer also has a test printout enclosed that was produced in the scope of production.
If the motors are moved manually, the display may light up. This is not a malfunction. A voltage induced by the movement in the mo-
tors causes the display to light up.

b)Installationofthelamentholder
Assemblyofthelamentholder
2xlamentholderpart
1xshaftforlamentholder
4 x nut M4 (black)
4 x cylinder head screw M4x20 (black)
Thetwolamentholderpartsareinstalledononesideoftheprinter
eachinthetwoupperrearholes(seearrowsinthegure).
Ifyouhavepurchasedthenisheddevice,the4cylinder-headscrews
and nuts will be enclosed.
Please note! The two lament holder parts must be in-
stalled so that they end with the rear edge of the respective
side part.

16
Fold the rear head cover up so that you can have access to the lower
attachmentscrewoftherightlamentholder(fromtherearview).
Insert one cylinder-head screw each into the two mounting holes.
Attach the upper screw hand-tight with a nut M4. It currently only
serves to secure.
Attachthelowerholdingscrewofthelamentholderandtightenit
at once.
Itiseasiesttoinstallthenutwithonengerandthentightenitwitha
hexagon socket wrench.
Remove the safety screw and fold down the rear head cover again.
Then install the safety screw you previously removed in the mount-
ingholeagainandthenthelamentholderontheleft(fromtherear
view).
Finally,inserttheshaftforthelamentholderatthetopoftheguides.

17
c) Inspection of the fan sheet and the actuation for the Z-limit switch
The two extruders should be in the home position. This means that they both need to touch the extruder holder on top.
ThefansheetheightmustbesetsothatthetwoupperscrewsofthetworearfansdonottoughtheX-plate(leftgure).Atthesametime,the
fansheetmustbeabovethetwotipsoftheextrudernozzles(rightgure).Ofcourse,itshouldalsobeasstraightaspossibleinreference
to the extruder nozzles.
Additional, you need to observe that the fan sheet must not touch the
attachment screws of the temperature sensors of the two extruders.
Also make sure to check the actuation for the Z-limit switch.
This must be aligned so that the square is aligned in parallel with the
light barrier and can move into it cleanly. Also check that the hexagon
threaded bolt and the counter nut of the actuation are tightened and
that the entire unit or the actuation cannot be adjusted.

18
d) Setup and transport
When setting up the 3D printer, observe that the mains switch or the mains line at the low power device combination
socket must be easy to reach so that the device can be switched off quickly and easily or be disconnected from the voltage
supply in case of malfunction. The emergency off switch must be easy to reach as well!
Ensure proper ventilation when setting up the device. Do not put the device down on soft support such as a carpet or bed,
etc. the air circulation also must not be impaired by other objects. This prevents heat dissipation from the product and may
leadtooverheating(dangerofre).
When setting up the device, make sure that it has a stable footing and place it on a stable underground. Persons may be
injured if the 3D printer drops.
When setting up the device, make sure that the connection cables are neither pinched nor damaged by sharp edges.
Always place the cables so that no one can trip over them or be caught in them. There is a danger of injury.
Neverplacethedeviceonanyvaluableorsensitivefurnituresurfaceswithoutsufcientprotection.
• Putupthe3Dprinteronalevel,stableandnon-vibration-sensitivesurface.
• Whenyouwanttotransportthe3Dprinter,secureallothermovablepartswithadhesivetapeorcabletiesorbestusetheoriginalpackaging.
Use only the original packaging for shipping! Particularly note that the two parts of the original packaging are pushed onto the heat
bed.
We assume no liability for any transport damage caused by improper packaging of the printer!
e)Mainsconnectionandrstactivation
The mains socket to which the 3D printer is connected must be close to the device and easily accessible to quickly separate
the device from the mains voltage in case of an error.
Do not let the mains cable come into contact with other cables.
Be careful when handling mains cables and mains connections. Mains voltage may cause potentially fatal electric shock.
Make sure that no cables lie around openly. Install cables professionally to prevent accidents.
Before plugging in the mains plug, ensure that the device voltage indicated at the 3D printer corresponds to the available
mains voltage. Do not connect the device if the indication does not correspond to the available mains voltage. Incorrect
supply voltage may lead to irreparable damage to the device and danger to the user.
If the printer suffers any malfunction or if there is any other problem, you can push the "emergency off switch" to quickly
disconnect the printer's voltage supply. Remove the problem before taking the printer into operation again. Then turn the
emergency off switch clockwise. This unlatches it.
• Plugthelowpowerdeviceplugofthemainslineintothelowpowerdevicecombinationsocketattherearofthedevice.
• Plugthemainsplugofthemainslineintoaprotectivecontactsocket.
