Tesseract 3D Printer Kit Instructions and Information
The Tesseract comes with a BigTreeTech GTR 1.0 board, it's a 32bit board running on an ARM processor - STM32F40IGT6
In order to update the firmware, you may need to deviate from your usual methods if you're used to using Arduino IDE - I absolutely could not get it to work using Arduino.
Instead you will need to download Visual Studio Code and add the Platform IO extension. Additionally, Marlin has an extension that can also be added to build and upload Marlin directly to your board.
More details on installing those and that process to come.
Download and extract the latest version of Marlin 2.0 somewhere on your computer.
You then need to download the following file ... File link to come ... for the configuration and configuration_adv and the pinout file (trying to get these added to Marlin)
Overwrite the following files with the ones for the Tesseract:
Open the main Marlin folder in VSCode - There's numerous ways to do it such as File > Open Folder.
Click on the PlatformIO tab on the left, looks like an Alien Head! lol and then click Build.
Then in your Main Marlin folder you should see a folder called .pio - if not, then you may need to show hidden files. Navigate to...
/Marlin/.pio/build/BIGTREE_GTR_V1_0 and copy the firmware.bin file to the MicroSD card that should have come with your BTT GTR 1.0.
Insert it into the GTR 1.0 MicroSD slot and turn the power on. It will auto flash the new firmware.
The Tesseract comes with a BigTreeTech TFT35 v3 Touchscreen. It can be swapped between Touchscreen mode and Marlin mode. You switch between the 2 by holding down the rotary encoder for a couple seconds, and then choosing which mode to display in.
If you'd like to download BTT's default firmware for the screen, head over to https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware
If you'd like to download the Alien3D custom icon set, download them here ... File Link Coming ...
There are 2 screen sets from BTT - a "Classic" and a "Unified". I personally like the Unified which is what comes default on the Tesseract.
When you download the firmware, simply upload the bin file (BIGTREE_TFT35_V3.*.bin) and the TFT35 folder containing the font and icons files, to the included SD Card and plug it into the TFT.
Turn the power on to the printer and it will auto update the firmware.
