chan@es and improvements. ghe hobby soon became a passion and Oosef @rew into one of the
leadin@ developers of Vdrien 4owyerJs internationalU open-sourceU RepRap pro!ect. godayU you can
see the Prusa desi@n in diWerent versions all around the worldU it is one of the most popular printers
and thanks to itU knowled@e about the 39 printin@ technolo@y si@niFcantly increased amon@ the
public.
Vll 39 printers by Oosef Prusa are open-source and based on the RepRap philosophy - you can use
your 39 printer to produce parts for buildin@ another 39 printer.
ghe lineup of Mri@inal Prusa devices is constantly eqpanded with new machines and up@rades. ghe
main @oal is to make technolo@y more accessible and understandable to all users.
Oosef Prusa also or@anizes workshops for the publicU participates in professional conferences
dedicated to the popularization of 39 printin@. jor eqampleU he lectured at the gA9q conference
in Pra@ue and NiennaU at Yorld Caker jaire in “ew …orkU Caker jaire in Rome or at the Mpen
Dardware ,ummit hosted by CTg. Oosef also teaches Vrduino at 'harles Bniversity and was also a
lecturer at the Vcademy of Vrts in Pra@ue.

•'hecks the len@th and free movement of each aqis
•ghis also veriFes proper stepper motor wirin@
•Heatbed and hotend proper wiring
•ghis also veriFes correct thermistor wirin@
B1B 8oading and unloading the 5lament
Mnce the ,elftest is FnishedU you can load a strand of Flament. Avery time you load a new FlamentU
make sure the tip is sharp and there are no bumps or other shapes that would prevent the Flament
from enterin@ the PgjA tube. jilament spools should be kept around the same level as the printerU
so the Flament strand can enter the PgjA tube without eqcessive bendin@.
15

-oading Llament
1. 'ut the end of the Flament strand to create a sharp tip. Tnsert the Flament into the eqtruder
PgjA tube ’ri@ht side of the deviceEU or into the short PgjA tube of the Flament sensor ’optional

I. Press the control knob to start loadin@ and push the Llament into the extruder until the
eqtruder drive @ears @rab the Flament.
X. ghe Flament is then loaded into the print head by the eqtruder @ears automatically. ghe printer
will ask you whether some plastic has been eqtruded from the nozzle. Tn case it wasnJtU choose
”“o+ and the printer will attempt to eqtrude more plastic.
ghe printer keeps track of the currently loaded FlamentU even when powered oW. …ou can
check the type of the currently loaded Flament in the bottom ri@ht corner of the 0'9 Cenu.-
iconmonstr-infov1.pn@
jor the neqt stepU keep the Llament loaded. TfU for some reasonU you need to chan@e the Flament
before jirst 0ayer 'alibration ’or at any other timeEU follow these instructions°

2. ghe printer will automatically preheat to the correct temperature, the beeper will notify you
when the preheatin@ Fnishes.
3. Press the control knob to start unloadin@.
5. Mnce the eqtruder @ears stop unloadin@ the FlamentU pull the Llament out from the PTFE
tube manually.
1I

B19 First 8a2er Cali6ration
ghis process will calibrate the distance between the tip of the nozzle and the probe. …ou can launch
the calibration at any time from LCD Menu - Calibration - First lager cal.
Cake sure the steel sheet is clean and thereJs no @rease on itU even Fn@erprints can cause an
issue. Zse the IPAKinfused cleaning wipe that came with your printer to clean it before you
start.
Mnce you start the jirst 0ayer 'alibrationU the printer will ask you whether Flament is loaded. Mnce
it isU the printer will probe the bed with Mesh Xed -eveling routine ’see chapter :.2 Cesh 4ed
0evelin@ for more informationE and start printing a zigKzag pattern on the print surface. ghe nozzle
will be at the hei@ht deFned by the C.T.“.9.V probe settin@. It must not by any means touch the
printing surface.
How to tune the nozzle heivht liTe durinv the test print
Mbserve the line which is bein@ eqtruded on the print surface. V new menu will automatically show
up - use it to tune the nozzle height in real time by turning the knob. ghe aim is to ad!ust the
nozzle hei@ht until the eqtruded plastic sticks nicely to the bed and you can see that it is bein@
sli@htly sLuished.
Make sure the testing pattern looks like the one on the left or middle picture. ghe picture on the
ri@ht displays both serious issues° nozzle too hi@h ’bent linesU shifted cornersE and nozzle too low
’plastic not eqtrudedE
1X

What to check:
•ghe top of the eqtruded plastic is sli@htly sLuished
•ghe corners of the zi@-za@ line are sharp and do not lift from the sheet
•ghe lines are strai@ht and stay on the sheet Frmly
•ghe endin@ boq has an even surfaceU there are no waves or @aps
4elowU you can see a close up of a print displayin@ Luality issues caused by an incorrect nozzle
hei@ht. ghe picture in the middle is the optimal Luality.
Yhe middle picture shows a correctlg calibrated Urst lager
B10 Chec,list
Tf you followed the steps described in the previous chapterU you are now ready to start your Frst
print. 4efore you startU letJs @o throu@h the Fnal checklist°
1. MINI is fully assembled and placed in a suitable location
2. The Lrmware is updated to the latest version
3. All of the calibration procedures were successful
5. A clean print sheet cleaned with IPAKinfused cleaning wipe is on the heatbed
I. jilament is loaded
B1v Starting the 5rst print
Mnce everythin@ is readyU you can navigate to the PRINT menu ’available only when a B,4 drive
is insertedE. Bse the knob to select a sample object from the list and observe the printer. Ye
recommend choosin@ the PRZSA logo, because it @ives you a @reat overview of how well you
tweaked the Frst layer durin@ jirst 0ayer 'alibration.
qou should aim for this leTel of Sualitg with gour Urst lager
1:

The nozzle will preheat to °9q QC independently on the selected Llament - this is to prevent
oozin@ of the Flament durin@ the initial phaseU which is Cesh 4ed 0evelin@. Mnce C40 is doneU the
printer will preheat the nozzle to the correct printin@ temperature and start with the initial pur@in@
line at the ed@e of the print bed. ghenU it will start printin@ the skirt around the ob!ect and the ob!ect
itself.
Pay close attention to the 4uality of the Lrst layer. Aqtruded plastic should stick to the sheet
nicely. TfU for some reasonU the nozzle is too hi@hU either try to lower it with the -ive Adjust
! function ’available throu@h the Yune menu durin@ an active print !obEU or stop the print
completelyU clean the sheet and re-run jirst 0ayer 'alibration from the 'alibration menu.
B1wA Remo-ing the print
