TINA2 Firmware

image

Summary

This is a forked repository that contains the firmware for the TINA2 3D Printer.

You can find the original repository at https://github.com/weedo3d/TINA2firmware

The framework of the firmware is based on the Marlin 1.1.x version.

MODIFICATIONS

In this fork, I did following changes:

  • remove the power loss recovery feature to prevent stutter during the print and increase the sd card life time
  • enable the heat bed and temperature sensor. You can use the heat bed from TINA2S as example (https://www.weedo3d.com/products/weedo-3d-printer-accessory-hot-bed-for-tina2s). Only little soldering for the sensor is required
  • replace the custom status screen with an heat bed alternative one
  • increase the lcd contrast value
  • remap unused pin 3 X_MIN_PIN into FAN1_PIN to enable part cooling feature. You can use the pin as data signal and add an MOSFET trigger module to drive the fan with higher power (e.g. 12V)
  • enable more precise bed leveling (Bilinear), that takes more measurement points but also more time

Product Version

  • TINA2 WIFI: TINA2 standard version with ESP32 WIFI module installed. Support remote control, send files via wifi, and online 3d model library.
  • TINA2 BASIC: TINA2 lite version, without WIFI module and protective shell.

Hardware Version

  • V2: The motherboard version is 62AS. The endstop type is lever limit switch.
  • V3: The motherboard version is 62AS. The endstop type is mushroom head limit switch.
