CoLiDo Desktop 3D Printer makes solid, three-dimensional objects by melting
PRINT-RITE PLA/ABS filament.
The designed 3D files are converted into CoLiDo command through computer
software“Repetier-Host”and sent to the CoLiDo printer via SD Card or USB
Cable. Then, the printer will heat up and melt PRINT-RITE PLA/ABS filament
and push it out from the nozzle to make a solid object layer by layer.
This method is called Fused Deposition Modeling or FDM.

1. 3D object can be adjusted such as scale down/up X/Y/Z, rotate X/Y/Z, copy,
mirror, autoposition and split before slice. After adjusting the object, It is
better to click “Center Object”.

2. For 3D printing layer by layer base on FDM process, we suggest printing
the model with OA structure. If printing the model with OB or OC structure
(Call Overhang Printing), the parallel or downward layer will fall down on
the model or on the platform due to no supporter to the layer. So, you need
add supporter for overhang object.

Remark:

OA – the structure is upward to stretch

OB – the structure is parallel to stretch

OC – the structure is downward to stretch

when the printer will is out of use

for a long period of time?

3D Printer

Does the printer support offline

printing?

Support offline printing by using SD card.

How long will it take to print

an object?

How to fix the clogged nozzle?

The required time depends on the object size and resolution level. The higher the resolution
level, the slower printing speed. The printer is configured with different print setting option:
Best, Standard, draft. After you select the printing setting to slice, the repetier software will
show the needed time .

1. Refer to chapter 6.6, once the nozzle reached the setting temperature, please press the
printer head arm and at the same time pull on the filament to extract it from the nozzle.

2. Refer to the label on the printer, clean the nozzle using longer Allen Key in the accessory.

For advanced user, you can push the knob to select “Control” to adjust Nozzle or Bed
temperature and printing speed during printing.

How can I know if the printer is

properly working？

Refer to chapter 6.2~6.4 in user manual, print one of the test file in SD Card supplied with
printer. (For example: PCT1.gco for PLA filament, ACT1.gco for ABS filament)

The filament cannot come out

from the nozzle during printing?

1. The platform maybe too close to the nozzle tip, which will prevent the filament extruding
from the nozzle. Please select "Prepare"-"Calibrate Mode" of LCD screen to re-calibrate
the platform. ( refer to chapter 6.2 in user manual)

2. Remove the filament from the printer head (refer to chapter 6.6 in user manual), cut the
filament tip flat, make a length of filament straight and re-load it into the printer head.
Make sure that the filament is properly inserted into the nozzle receiving port.

3. Disassemble the printer head, check the gear which is pulling the filament into the nozzle.
If there are presence of filament powder residue is filled in, clean the gear using the brush.
Check also if the gear tooth is damaged. If yes, replace the gear with a new one.

The printer makes a clicking noise

when printing?

1. The filament is not properly inserted into the nozzle . Please unload the filament,
cut the end of the filament flat and re-load into the printer head. (refer to chapter 5.8)

2. It maybe a short length of the filament blocked in the nozzle from the last time it printed.
Refer to chapter 6.6 in user manual, heat the nozzle and push the blocked filament
into the nozzle tip by loading new filament, the blocked filament will be melted out.

The filament cannot be removed

from the printer head?

1. Check if the nozzle actual temperature reachs the setting temperature;

2. Refer to chapter 6.6 in user manual, when the nozzle actual temperature reach the
setting temperature, press the printer head arm and push a bit filament into the
nozzle until the filament come out from the nozzle, then pull the filament out quickly.

Question Solution

Question Solution

The printed sample stick to the

platform too tight and cannot

be removed?

1. Please wait a few minutes for the platform and the printed samples cooldown, then
remove the printed sample.

2. If the printed samples still stick to the platform tightly, please carefully remove it using
a scalpel.

If you do not use the the filament for a long time, keep your filament spool or cartridge in
a closed plastic bag to avoid the filament absorbing the moisture. Also, ensure insert the
filament tip into the small hole of the spool to avoid filament entangle when use next time.

Chapter 9 Troubleshoot

The printed object cannot stick

to the platform?

1. Make the temperature setting correct. PLA, nozzle temperature is 205℃, platform
temperature is 70℃; ABS: nozzle temperature is 220℃, platform temperature is 110C.
Make sure the selected setting is matched with the material you are using.

2. Re-calibrate the platform to meet "calibration standard condition" (The test sheet must
be lay down flat in the platform and the test sheet must be touching the nozzle tip).

3.Make sure that the glass platform you are using is correct base on the filament material.
No dust, oil or damage coating on the glass platform. If yes, please clean up using lint-free
cloth or replace the platform.

The printer cannot read the files

on SD card and cannot start to

print with SD Card?

1. Turn off the printer and turn on again the printer.

2. If the printer still cannot read the file, please check if the files saved in SD card in
