# Anycubic i3 Mega Marlin Firmware with TFT support
|
|
|
|
This is my slightly customized version of the [Marlin Firmware](https://github.com/MarlinFirmware/Marlin), gratefully based on [derhopp's repo](https://github.com/derhopp/Marlin-with-Anycubic-i3-Mega-TFT) with his remarkable efforts to get the Anycubic i3 Mega TFT screen to work.
|
|
|
|
I am running this version on an i3 Mega Ultrabase V3 (for distinction of the different versions, check [this Thingiverse thread](https://www.thingiverse.com/groups/anycubic-i3-mega/forums/general/topic:27064)) with FYSETC TMC2208 V1.2 installed.
|
|
Basically, this should work on every Ultrabase version that has no bed leveling sensor and two Z-axis endstops.
|
|
|
|
#### Why use this?
|
|
|
|
While the i3 Mega is a great printer for it's price and produces fantastic results in stock, there are some issues that are easily addressed:
|
|
|
|
- Very loud stock stepper motor drivers, easily replaced by Watterott or FYSETC TMC2208.
|
|
-- To do that, you'd usually have to flip the connectors on the board, this is not necessary using this firmware.
|
|
- Fairly loud fans, while almost every one of them is easily replaced, the stock FW only gives out 9V instead of 12V on the parts cooling fan so some fans like Noctua don't run like they should. This is fixed in this firmware.
|
|
- Thermal runaway protection: Reducing fire risk by detecting a faulty or misaligned thermistor.
|
|
|
|
## Changes:
|
|
|
|
- Thermal runaway protection enabled
|
|
- TMC2208 configured in standalone mode
|
|
- Stepper orientation flipped (you don't have to flip the connectors on the board anymore)
|
|
- Some redundant code removed to save memory
|
|
- 12V capability on FAN0 (parts cooling fan) enabled
|
|
|
|
### Additional features by derhopp:
|
|
|
|
- Subdirectory support: you have to press the round arrow after selecting a directory
|
|
- Special menu in the SD file menu: you have to press the round arrow after selecting a special menu item
|
|
|
|
|
|
### Todo:
|
|
- [ ] Tweak TMC2208 steps

|
|
|
|
Marlin is an optimized firmware for [RepRap 3D printers](http://reprap.org/) based on the [Arduino](https://www.arduino.cc/) platform. First created in 2011 for RepRap and Ultimaker printers, today Marlin drives a majority of the world's most popular 3D printers. Marlin delivers outstanding print quality with unprecedented control over the process.
