6.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printtemperaturesfortheprintingheadandheatingbed(preassembleddeviceonly),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thenprintstheprint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thelamentrolltotheprinthead(extruder).
Intheextruder,thelamentmaterialismeltedandthenappliedtotheprintingplateviaaneextrudernozzlelayerbylayer.
TheextrudermovesintheX-andY-directions,theprintingplatemovesintheZ-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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.

c)InstallationoftheRepeaterHostSoftware
• Installthele"setupRepetierHostRenkforce_x_x_x.exe" from the directory "Repetier-Host"fromthedownloadpackage(x_x_xdesig-
nates the software version here).
InstallationofthecustomversionoftheRepetier-Host requires administrator rights, since the necessary conguration les and
printer settings will not be installed otherwise. If the corresponding message appears in Windows®,conrmitwithYesinanycase.
The installation will otherwise be interrupted.
 Ifsetupasksifyouwanttoinstalltheserialdrivers("Installserialdriver"),dothisinanycasefortherstinstallation,sincetheprinter
will not be recognised otherwise.
• Alternatively,theinstallationleforthebasicversionofthesoftwarecanalsobedownloadedfromwww.repetier.com.There,MacOSX-and
LINUXversionsofthissoftwareareofferedaswell.
Prerequisites for installing under Windows®:
Microsoft .Net Framework 4 must be installed on the computer. This software can be downloaded free of charge from
www.microsoft.com or installed subsequently in the operating system via the Windows®features.
 ThefurthersystemrequirementsforinstallationofRepetier-Host(alsoforotheroperatingsystems)arefoundonwww.repetier.com.
Updates for Repetier-Host are regularly published under www.repetier.com. Updates of the custom version can be found on
www.conrad.com in the download area on the product page of the 3D-printer.
d)InstallationandUpdatingoftheFirmware
Atdelivery,normwareisinstalledonthemainPCBoftheconstructionkit.Thermwaremustbeinstalledoncebefore
installationofthemainPCB.Installationtakesplaceviathermwareupdater.
 Thisstephasalreadybeenperformedinproductiononthepreassembleddevice.However,werecommendthatyoucheck
beforecommissioningwhetherthelatestrmwareisalreadyinstalled.
 Newversionsofthermwarearecontainedinthedownloadpackage"BUNDEL_Vx_x_x_RENKFORCE_RF500".
 Thefollowingdescriptionisvalidforrstinstallation(constructionkitonly),aswellaslaterwhenupdatingthermware
(constructionkitandpreassembleddevice).
 Alternatively,chapter"20.FirmwareUpdate"describeshowtoinstallthermwarewiththeArduinoTM-software.
Update process
• Afteryouhaveinstalledtherepeaterhostsoftwareincl.theserialdrivers,connectthemainPCB(onlytheArduinoTM-PCB without the ad-
ditional PCB) to your computer by USB.
 ThePCBissuppliedwithpowerviaUSB.Thisisenoughtoinstallthermware.
• Startthele"FirmwareUpdater.exe"withadministratorrights.Youcannd
the program in the unpacked download bundle, in the directory "Firmware
Updater".
• First,setyourlanguageifnecessary.Forthis,clickthemenu"Language" or "Sprache". Select English or German as your language.

13
• Now select the desired serial connection. For this, click
"Select Port".Ifmorethanonedeviceisdisplayed,briey
disconnect the main PCB at the USB connection and then
recommend it. The device that disappeared briey is the
right one.
• Toselectthermwarele,click"Load Firmware File".
• Usually,thefolderinthedownloadbundlethatcontainsthe
rmwarewillbeopenednow.Ifthisisnotthecase,open
the folder "Firmware-Hex" manually. Then open the cor-
responding subfolder "RF500-withBed"(forthepreassem-
bled device) or "RF500-withoutBed"(fortheconstruction
kit).Openthermwarele"RF500_Vx_x_x.hex" in it.
• Tostarttheupdate,click"Update now".
• Thermwareversionwillbedisplayed.Conrmwith"OK".
• Tostarttheupdate,click"Update now" in the main window.
• Therewillbeanotherquerywhetheryoureallywanttoperformtheupdate.Conrmwith"Yes".
 Theupdatewillnowbeinstalled.Duringthis,thedisplayinthelowerleftoftheupdaterandonthemainPCBwillash.
• Oncethemessageshowsthattheupdateiscomplete,conrmitwith"OK".
• Next,pushthebuttonatthemainPCB,waitforafewsecondsandthendisconnectthecablefromtheUSBconnectionagain.
If you update later, while the PCB is already installed, remove the USB cable and voltage supply from the printer after the update.
Wait for about 20 seconds to connect both again.

10.AssemblyoftheMechanicalParts
Thischapter("10.AssemblyoftheMechanicalParts")generallyisonlyrelevantforpurchasersofthemakerconstructionkit/con-
struction kit. Owners of the preassembled device can skip this chapter. However, the chapter is helpful when there is an error or
smaller repairs are necessary.
a) General Information
Takeenoughtimefortheassembly.Hurryingoftenleadstomistakesthatmaydamagecomponentsorruinthetimebenet
by elaborate rework.
Theworkplaceshouldbesufcientlylargeandcleansothatthedifferentcomponentsandassembliescanbeputdownand
installed easily.
 Alwaysobservetheimagesduringassembly.Here,theassemblylocationsandcorrectalignmentofthecomponentsare
shown.
 Allmechanicalcomponentsoftheconstructionkitareproducedextremelyprecisely.Neverapplyanyforceduringassem-
bly.Allpartscanbeassembledwithoutanygreatapplicationofforce.Ifthisisnotthecase,rethinktheassemblystepand
rereadthecorrespondingdescriptionintheseinstructions.
When tightening the screws, ensure that you do not tighten them too tightly. Many screws are turned into aluminium
threadsandthereforemustnotbetightenedasfarasitwouldbepossible,e.g.,insteelthreads.Atablewiththerecom-
mendedtighteningtorquesofthescrewscanbefoundintheappendixoftheseinstructions.
Ifyouhaveorderedanoperationalaccessorieskit(e.g.housingkitorheatingplatekit)alongwiththeconstructionset,readthein-
structions of the respective kits before installing the construction kit. This may change individual work steps.
Sort the screws by size before assembly. This facilitates assembly, since you do not have to look for individual screws.
The delivery includes some screws, nuts and other small parts in larger numbers than necessary. They are meant as replacements
in case a screw or similar material is lost in assembly.
 Forcylinderheadscrews,thelength(l)ismeasuredwithoutthescrewhead;forcountersunk-headscrews,thelengthmeasurement
takesplacewiththescrewhead.Thediameter(d)isalwaysmeasuredbythethread.
Applicationofthethreadlockervarnish
In the following instruction, some screws can optionally be secured with threadlocker varnish. This is indicated accordingly in the text.
Procedure:
Put a small drop of threadlocker varnish medium-strength onto the thread start. Observe that you must only use a small drop as shown in the
following screen.

16
Useoftheslotnuts
Pushtheslotnutintothealuminiumproleslotturnedby90°longi-
tudinally.
Push, e.g., a small hexagon socket wrench or a similar tool carefully
into the slot nut's thread.
Turn the slot nut up until it "latches" and is held cleanly in the guide.
Now you can move it back and forth as desired.
When you tighten the respective screw in the slot nut, always make
sure that the slot nut is placed cleanly in the nut.
If you have to take out the slot nut, push it to the side so that it slips
from the guide. Then turn it as when inserting. If the slot nut has the
position shown in the 1st picture on this page, tip the thread up by
90°.Ifthenutprotrudesfromtheslot,justpullitout.
Alternatively,andwhiletheslotofthealuminiumproleisstillacces-
sible, you can also push the slot nut into the slot from the side or pull
it out that way.
