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.

Homing

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.

image38.png

image39.png

Level Bed

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.

image40.png

Endstops

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.

image41.png

image42.png

Disable Steppers

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

image51.png

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

Probe Z Offset

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.

Sensore filamento: On

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.

image62.png

image63.png

Quiet Mode: Off

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.

image64.png

Powerloss Recove: Off

Press the button to switch OFF/ON .

image65.png

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.

Smart Temperature

Press the button to switch OFF/ON .

image66.png

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.

WIFI Network

image80.png

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

image81.png

image82.png

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.

WIFI Info

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.

image83.png

image84.png

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

image85.png

WIFI QR Code

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

image86.png

image87.png

Network Test

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.

image88.png

image89.png

image90.png

Unreg. Cloud

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

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

image91.png

image92.png

WIFI Reset

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.

image93.png

image94.png

image95.png

Shows ".gco" or ".gcode" print files on TF card.

image96.png

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.

image97.png

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.

  1. 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.

image119.png

image120.png

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)

image121.png

image122.jpeg

Save Printing and Off

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

image123.png

image124.png

image125.png

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.
