Press knob to open two-screen Prepare menu. Turn knob to scroll.

Use to properly unload and load filament. Do not pull filament out directly to avoid clogs.

Change Filament:

Select filament type to heat nozzle.

At 240°C, filament auto-unloads.

Beep indicates unload complete, insert new filament as prompted.

Load Filament:

Auto-heats nozzle and loads filament. Press knob during heating/extruding to cancel.

Unload Filament:

Auto-heats nozzle and unloads filament. Press knob during heating/retracting to cancel.

Manually control stepper motors for troubleshooting.

X/Y/Z Axis: 10mm, 1mm, 0.1mm increments

Extruder: 10mm, 1mm, 0.1mm increments

Knob controls bidirectional movement

CAUTION:

RANGE IS 0-100MM PER AXIS. PERFORM “AUTO HOME” FIRST FOR CORRECT NOZZLE COORDINATES. WITHOUT HOMING, CURRENT POSITION BECOMES ORIGIN, LIMITING JOG RANGE.

AXIS MOVEMENT LIMITED BY ENDSTOPS. BROKEN OR MISWIRED ENDSTOPS MAY CAUSE MOTOR TO NOT STOP OR MOVE.

EXTRUDER HAS THERMAL PROTECTION, ONLY MOVES WHEN NOZZLE IS >170°C.

Moves nozzle and platform to origin (X=0, Y=0, Z=0). Can home XYZ together or separately. Helps troubleshoot motor or endstop issues in a specific direction.

Auto-levels platform using proximity sensor. Done at each print start to ensure proper nozzle-platform distance.

Can diagnose proximity sensor issues - error displays if sensor fails.

Shows X/Y/Z endstop and proximity sensor status. Moving nozzle or platform to trigger endstops changes each one's state.

Helps diagnose faulty endstops or sensor - no state change indicates failure.

Releases stepper motor locking, allowing manual nozzle and platform movement.

Press knob to open two-screen Control menu. Turn knob to scroll.

Manually set nozzle and bed temperature:

Select Nozzle or bed, turn knob to desired temp, press to confirm.

Info Screen shows real-time temp during heating. Heating continues if exiting to other tasks.

To stop heating, re-enter menu and decrease temp to 0.

Preheat PLA/TPU/PETG: Background heats nozzle to 210°C/220°C/230°C respectively.

After bed leveling, sets nozzle-platform gap. Press knob to save.

Too small: Nozzle may scratch platform or clog.

Too large: Poor model adhesion, lifting.

Recalibrate after replacing nozzle or sensor.

Turn knob to precisely adjust nozzle height for smooth, flat first layer.

Select from: English, Chinese, French, German, Spanish, Italian, Japanese, Portugal, Dutch, Turkish and Russian.

Turn knob to select, press to save and exit.

Press “LED Control” to open the LED switch menu.

Press the knob to confirm and save.

Press the button to toggle the filament break detection function ON or OFF. This feature is enabled by default. When no filament is loaded and you attempt to start printing or during printing, a reminder will automatically appear on the screen.

Press the button to switch OFF/ON .The mute function is turned off by default. If you choose to enable it, the printer will significantly reduce its printing speed in order to lower the operating noise.

Press the button to switch OFF/ON .

If enabled, saves print progress every 10s. After unexpected power loss, prompts to resume on restart.

Disabled by default. Enable if desired.

IMPORTANT:

PROGRESS SAVED TO “.BIN” FILE ON TF CARD EVERY 10S, OVERWRITING PREVIOUS DATA. ON RESTART AFTER SUDDEN POWER LOSS, CHECKS FOR “.BIN” FILE AND PROMPTS “CONTINUE PRINTING, STOP PRINTING”. CONTINUING READS SAVED PROGRESS, STOPPING DELETES “.BIN” FILE.

SINCE SAVING ONLY EVERY 10S, RECOVERY MAY FAIL DUE TO TIME INTERVAL.

Press the button to switch OFF/ON .

The smart temperature feature is turned on by default. The mainboard can monitor the ambient temperature and increase the temperature of the nozzle and platform according to the ambient temperature.

Shows current firmware version.

Copy “.wfx” firmware file to TF card root. Decompress first if

  needed. Rename to "flash.wfx".

Insert TF card and select Firmware Update.

Printer checks version and updates.

Copy “.efx” WiFi firmware file to TF card root. Decompress first if

  needed. Rename to "wifi.efx".

Insert TF card and select WiFi Firmware Update.

Printer checks version and updates.

Resets all parameters to factory defaults.

Modify advanced parameters. Beginners use defaults.

LCD Contrast: Adjust screen clarity

Retract: Auto-retract, amount, speed, etc.

Max Speed (mm/s): Same as in slicer

Acceleration: Increase print speed

Jerk: Increase acceleration ramp time and corner/jitter speed

Probe Offsets: Set X/Y/Z offsets

Filament: Set extruder compensation

Store Settings: Save changes

Load Settings: Apply saved changes

Press knob to open two-screen Control menu. Turn knob to scroll.

The network function of TINA2S has two connection modes, local mode, and remote mode.

Local mode: In the same local area network, Wiibuilder or Cura on the computer can connect to the 3D printer, and perform remote control or send print files. To use local mode, the 3D printer should be connected to the local WIFI network.

Remote mode: Use our APP, PoloPrint Cloud, remotely control the 3D printer or download the print model. With the remote mode, you can remotely control the 3D printer from any location. To use remote mode, the 3D printer should be connected to the WIFI network and registered with the APP. Notice, a 3D printer can only be registered by one APP account.

Press “WIFI Info” to open the WIFI info screen. It will show the WIFI firmware version, the serial, IP address, AP name, and the connection status of the cloud server.

Before the network is configured, “OFF” and “UNKNOWN” will be displayed.

Only after configuring the network and registering in the APP will the 3D printer connect to the cloud server.

Press “WIFI QR Code” to show the QR code generated by the device serial. Used for App scanning networking and cloud access.

Press “Network Test” to start testing the current network connection and response time.

If the printer encounters network or app-related issues, use this function to check whether the network is properly connected or if the connection speed is too slow.

Press “Unreg. Cloud” to view the instructions for deregistering from the cloud platform.

Please follow the tutorial to complete the operation in the app.

Every time TINA2S is turned on, it will automatically connect to the WIFI network that was successfully connected to the last time. If you need to connect TINA2 to a new WIFI network, you should execute the reset WIFI setting function to clear the saved WIFI network information.

Shows “.gco” or “.gcode” print files on TF card.

If the correct printer is not selected when using slicer software like Wiibuilder or custom Cura, the generated G-code file will be incompatible with the printer, resulting in an 'incompatible' error message. Make sure to select TINA2S.

Select file and press knob for print info. “Print” starts printing.

To prevent damage, checks machine model in file. Blocks print if model mismatched or missing. Use Wiibuilder or custom Cura version and select correct model when slicing.

NOTE: FILE NAMES ≤20 CHARACTERS TO AVOID DISPLAY ISSUES.

During print, press knob for print settings menu.

Pauses print and moves nozzle to pause position. Can resume from pause.

Cancels current print and returns to Info Screen.

IMPORTANT:

REMOVE PRINTED MODEL FROM PLATFORM AFTER STOPPING.

Same steps as Change Filament in Prepare menu:

Heat to set temp. Auto-unload at temp.

Beep, insert new filament, press knob.Auto-load at temp.

To change:

Select setting, turn knob to desired value.

Press knob to confirm.

1.Speed

2.Nozzle temp

3.Nozzle temp

Advance K

Advance K (Linear Advance) is a parameter used to optimize extruder pressure control.

It dynamically adjusts the extrusion flow during acceleration and deceleration phases to compensate for material pressure changes inside the nozzle.

This improves surface detail and print quality while reducing issues such as stringing and blobs.

In simple terms, it helps the extrusion keep up with speed changes, especially during rapid accelerations and decelerations.

5.Probe Z Offset

IMPORTANT:

Z OFFSET MICRO-ADJUSTS NOZZLE HEIGHT IN REAL-TIME TO CHANGE GAP:

INCREASE BY 0.2MM IF GAP TOO SMALL (NO EXTRUSION)

GRADUALLY DECREASE IF GAP TOO LARGE (POOR ADHESION)

Saves progress, moves to pause position, allows safe power off. Prompts to resume on next power on.

IMPORTANT:

“PAUSE PRINT” AND “SAVE PRINT” TRIGGER HOMING. MECHANICAL ENDSTOP TOLERANCES CAUSE SLIGHT DEVIATION ON EACH HOME, POTENTIAL SEAM/SHIFT AT RESUME POINT.

PRINT MODELS IN ONE SESSION WHEN POSSIBLE TO AVOID THIS.
