WEEFUN TINA2S

The WEEFUN TINA2S is an FDM 3D printer from WEEFUN with a 100 x 120 x 100 mm build volume.

Specifications

The WEEFUN Tina2S represents the refined evolution of the popular base Tina2 model. This version preserves the highly compact form factor of its predecessor but integrates crucial hardware upgrades that expand the compatible material range, enhance operating reliability, and improve overall user comfort.

• Build Volume: Retains the compact print volume of 100 x 120 x 100 mm. The small build footprint is advantageous for quick prints of miniature models, while eliminating common mechanical issues associated with larger heated beds (such as thermal gradients or frame twisting).
• Kinematics: Built upon a Cartesian XY-Head Z-Bed kinematics scheme with a cantilevered X-axis gantry.

Calibration

Despite automation enhancements, calibrating the Tina2S requires specific steps related to the heated bed and Wi-Fi features:

• Thermal-Stabilized Z-Offset Calibration

Unlike the base model, both the print bed and hotend must be preheated to 60°C and 200°C respectively before calibration. The thermal expansion of the spring steel sheet affects the proximity sensor's readings.

Common defects

• Hardware defects and mechanical weaknesses
• DC Jack Overheating (DC Plug Failures):
• Symptoms: The printer restarts unexpectedly during heating, and the barrel power plug on the back feels hot to the touch.
• Cause: The introduction of a heated bed increases the overall current draw near the limits of the standard barrel connector. Poor connection quality causes high resistance and heat.
• Solution: Clean contacts.

What it is used for

Best use-cases

• PETG and TPU Printing for Functional Brackets:
• Why: The heated bed and 250°C hotend capability allow for printing tough and flexible parts like seals, brackets, and simple gears.
• Cloud-Managed Classrooms:
• Why: Teachers can manage multiple units via Polar Cloud, approving student submissions and checking progress remotely.
