A Mouse (USB wired or wireless*)

(*Keyboard and Mouse connection can be made via a wireless USB dongle).

3. Insert supplied USB Stick Drive into any available USB port on PC Mother Board connection panel.

4. Attach Mains Power Cable, as shown below and turn on Printer Power Supply Switch then press and release

the CPU Power Button located to the right of the CPU panel (shown above in blue or green).

Rev001/01/2018 Kora Pro PC

** If PC functionality is not required at this stage - simply press and hold the CPU Power Button and operate the 3D Printer as described from

8. below.

5. Follow instructions on monitor to load and configure Windows 10 from the previously inserted USB Drive. YOU

MUST ONLY SELECT WINDOWS 10 HOME EDITION - otherwise your software key supplied with your Windows

10 Disk inside the box will be invalid.

6. Once Windows 10 has completed the installation, connect to the Internet following the Windows 10 on screen

instructions (you may require a cable connection from the PC Motherboard your Internet router or use a USB wireless

Internet dongle, if your router offers wireless connectivity).

7. Once connected to the Internet, download and install the free Open Source Arduino IDE and Repetier-Host

Software programs from the links below.

Arduino IDE - https://www.arduino.cc/en/Main/Software

Repetier-Host (optional donation) - https://www.repetier.com/download-software/

Repetier-Host (no donation) - https://www.repetier.com/download-now/

For users unfamiliar with Repetier-Host, full details of Repetier-Host set-up for the Kora Pro 3D PC please

refer to the document ‘Instructions_RepetierHost_KoraPro3DPC_Rev01.pdf’ - located on the USB Stick Drive

supplied with the machine in the sub-folder /Kora/Instructions.

8. Attach Filament Spool Holder as shown below.

9. Take a reel of filament and remove from packaging, taking care to save the plastic bag and bag of silicon for

storing filament after use (It is recommended not to store filament for a prolonged period in any kind of moist/damp

environment).

You will notice the free end of the filament is held in the hole on the reel. It is important to ensure the filament is able

to unravel freely from the spool, without being knotted or snagged. Keeping track of the filament end is good practice

and should be returned to the hole when the spool is not in use.

Place filament spool on to the spool holder as shown overleaf.

LOADING THE FILAMENT

To insert (or to change) the filament, the machine Hot End extruder must be heated first. This can be done in

two ways, either using the Repetier-Host software or via the onboard LCD control panel.

Using the control panel go into 'Quick Settings' by turning the jog wheel and select 'Preheat PLA/ABS' (depending

on which filament you are using) and press the jog wheel.

WARNING: 'Preheat PLA/ABS' heats the printer hot end assembly and the print bed to the required

appropriate temperatures - use caution not to touch either whilst heating or hot (between 50 and 260⁰C)

Select 'Back' on the control panel to return to the 'Main Menu'. This will show you the current Extruder and Heated

Bed actual temperatures (to the left) and target temperatures (to the right) after heating is complete. Once the target

temperatures have been achieved, the extruder is ready to take filament.

Make sure the end of the filament is cleanly cut and straighten 40mm using your fingers. This will make it easier

to feed the filament through the filament feeder mechanism.

With one hand gently squeeze/pinch the filament extruder arm as shown below, and carefully feed the filament up

through the 'rectangular nipple' past the filament drive gear and up into the PTFE feeder tube. Do not over

squeeze/pinch the filament extruder during filament loading as this will make feeding the filament more difficult.

Rev001/01/2018 Kora Pro PC

While still squeezing/pinching, continue feeding the filament through the PTFE Feeder Tube until melted filament is

extruded from the HOT Nozzle. Note that the printer bed must be away from the Nozzle tip to allow the filament to be

extruded freely. The Printer Bed height can be adjusted at this point away from the nozzle by manually rotating the

Bed Lead Screw anti-clockwise - (the long threaded rod at the rear/centre of the machine), using finger and thumb.

Once about 60mm of filament has been extruded from the Nozzle, release your squeeze/pinch to engage the 'filament gear'

and 'bearing' on to the filament. Trim the excess extruded filament from the Nozzle with tweezers or scissors, making sure

not to touch the HOT Nozzle or the aluminium Heater Block directly above the nozzle. This block and

the nozzle can reach temperatures in excess of 260⁰C.

The filament is now loaded.

PLEASE NOTE -

NEVER shut down the built in PC or turn off the Mains Power Supply if the Nozzle temperature is showing

above 60⁰C on the Printer LCD screen - failure to follow this instruction can cause a machine Nozzle

blockage. If this is done in error - immediately restoring the power will avoid possible Nozzle blockage.

LEVELING THE HEATED

PRINT BED

It cannot be stressed enough that levelling the printer bed correctly is essential to achieve good adhesion between

the printer bed and the first layer of all your 3D prints.Only VERY LIGHT contact is required between the tip of the

nozzle and the printer bed, ideally NO "gap" should be present. However, a sheet of standard 80 gram printer paper

can be used to gauge when the nozzle is very close to the printer bed during adjustment, by feeling friction on the

paper as the nozzle starts to squeeze the paper against the printer bed.

Although so called 'automatic printer bed levelling' could be easily installed on this machine, only manual printer bed

levelling has been installed on this machine. This is much more consistent and accurate and after a little practice,

proves a far better levelling method than any 'automatic' alternatives. Future additional Bed Levelling is only required

if the first print layer appears too close (nozzle scraping on the print bed) or too far away (first print layer does not

adhere sufficiently) from the print bed.

It is good practice to level the Printer Bed after loading the filament with the Nozzle and Heated Bed at printing

temperature, before each print. This allows for the Nozzle to be clear of hardened filament - allowing accurate

judgement of light contact between Nozzle and Printer Bed.

It also allows, once bed levelling is complete, to proceed straight to printing without the risk of the interfering with

the levelled bed.

Experience in this procedure will be gained quickly, through practice.

There are several ways to ensure that the bed is level and ready to print.

Note: Before attempting to level the printer bed using method a. or b. (page 10) manually rotate the Bed Lead Screw

clockwise until the Nozzle lightly touches the printer bed. At this position the lowest LED on the Hot End PCB (Z home

limit switch indicator) should be illuminated. If it is not illuminated, turn all the thumb screws (x4, located at each

corner of the headed print bed) one full turn anticlockwise (to lower printer bed) and repeat test from 'Note:' (above).

Continue this procedure until the lowest LED on the hot end PCB illuminates when the nozzle is just touching the bed.

a) MANUAL METHOD (preferred method)

1. Using Control Panel, press the Jog Wheel once and scroll down to 'Position' on the printers LCD screen,

press the Jog Wheel. Scroll down to 'Home Z' and select by pressing the Jog Wheel, the printing bed will rise

towards the Nozzle then stop in a locked position.

2. When it reaches the top, using the Mechanism Support Rods to manually move the main Hot End holder

block to all four corners of the printer bed - at each corner use the Thumb Screw below that particular corner

of the Printer Bed to adjust the printer bed up and down so that it lightly touches the brass tip of the Nozzle

in all positions.

3. When complete re-check all four corners again and finally check the middle of the Printer bed.

4. You have 6 minutes to complete the above process after selecting 'Home Z', after this time the Z motor will

time out and unlock - thus preventing accurate Printer Bed levelling - if this happens, simply repeat from step

a)1. above.

b) USING SD CARD (alternative 'Semi-Automatic Levelling')

1. Insert SD card (if already inserted remove and re-insert). On the file list shown on the Control Panel LCD

display scroll down and select the file named ‘Kora_levelling.gco’. The printer will home all axes, then

automatically move the Hot End holder block to far right hand corner slowly raising the Printer Bed

towards the Nozzle.

2. When the bed stops rising check that the Nozzle is lightly touching the Printer Bed surface. This is adjustable

using the Thumb Screw under the far right hand corner of the bed. You have 10 seconds after the bed has

stopped rising to make this adjustment correctly. After 10 seconds the bed will slightly lower and the Nozzle

will move to the far left hand corner to repeat the process.

3. The process will be repeated for the remaining corners, allowing for adjustment each time.

4. The Nozzle will then move to the centre for 5 seconds to check the adjustment.

5. The Control Panel will then display 'One Quick Check!' and will repeat everything from 2 above but this time

only pausing for 5 seconds (To allow final fine tuning).

6. The Nozzle will return to its home position (rear right hand corner).

7. You can repeat the process as often as you like, until completely satisfied that the Nozzle is lightly

touching the Printer Bed in all positions. To repeat if required, start again at step b)1.above.
