***Custom Firmware for SUNLU T3 based on Marlin 2.1.2 bugfix January 2023***

*** Added the Source Code from SUNLU to “other Files”***

No USB functionality!

Since I don't use USB I didn't test this, but was told it doesn't work. Will check the pins and make an update asap.

 

Installation instruction:

- Turn printer off
- Place firmware.bin file on your Card
- start printer
- wait
- ...
- profit


Following Things work with the Sunlu T3:

- Automatic Bed Leveling
* now with 5x5 points
* not on any G28, use G29 for ABL (could implement in start G-Code if you want to)
* will restore after G28

- BL Touch assistet bed tramming

- Double click to babystep

- Higher Hotend Temperature
* since I have an all metal hotend installed i raised the temperature to 285 °C - be careful with the standard hotend!!
            
- PID Tuning for BED and Hotend 
*use the custom Menu for Tuning

- I calibrated my Printer (x, y an E Steps/mm)
*if this doesn't fit your Printer you can reset the steps/mm in the advanced configuration menu to:
 X - 80 steps/mm
 Y - 80 steps/mm
 Z - 800 steps/mm
 E - 135,1 steps/mm
*save to EEPROM!

- Runout Sensor is working - even with Jam Detection. Standart procedure at runout error is the M600 filament change workflow.


Whats not working:

- fastmode is not implemented (yet) but can be achieved through manually rising the acceleration and jerk settings (raise speed via feeding speed or via slicer settings)
*i don't know if I'm able to implement fast printing, because I don't use it and I'm lacking time for this.
