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)).
|
||||
Basically, this should work on every Ultrabase version that has two Z-axis endstops.
|
||||
|
||||
**The new Mega-S is not officially supported. You can try your luck, but I have no means of troubleshooting issues with that machine. E-steps need to be set to 384 (`M92 E384.00` + `M500`), and afterwards calibration is highly recommended as per the instructions on the [Wiki](https://github.com/davidramiro/Marlin-AI3M/wiki/Extruder-Calibration/).**
|
||||
The new **Mega-S** should work too, but you will need to enter those two commands to make the new extruder work:
|
||||
```
|
||||
M92 E384
|
||||
M500
|
||||
```
|
||||
Afterwards, calibration is highly recommended as per the instructions on the [Wiki](https://github.com/davidramiro/Marlin-AI3M/wiki/Calibration/).

Looking for a **BLtouch firmware**? Head [this way](https://github.com/MNieddu91/Marlin-AI3M-BLTouch)! Mounting and configuration instructions are included.
|
||||
|
||||
Note: This is just a firmware, not magic. A big part of print quality still depends on your slicer settings and mechanical condition of your machine.
|
||||
|
||||
#### Make sure to take a look at the [Wiki](https://github.com/davidramiro/Marlin-AI3M/wiki/), especially the [FAQ](https://github.com/davidramiro/Marlin-AI3M/wiki/Frequently-Asked-Questions).

- Estimated print times from your slicer might be slightly off.
|
||||
- Special characters on any file or folders name on the SD card will cause the file menu to freeze. Simply replace or remove every special character (Chinese, Arabic, Russian, accents, German & Scandinavian umlauts, ...) from the name. Symbols like dashes or underscores are no problem.
|
||||
**Important note: On the SD card that comes with the printer there is a folder with Chinese characters in it by default. Please rename or remove it.**
|
||||
- Cancelling prints via display is buggy sometimes, simply reboot the printer when the menu shows an error. Protip: Switch to OctoPrint.
|
||||
- Cancelling prints after pausing may show an error. Simply resume the print before canceling. Protip: Switch to OctoPrint.

- Even better print quality by adding Linear Advance, S-Curve Acceleration and some tweaks on jerk and acceleration.
|

- Thermal runaway protection: Reducing fire risk by detecting a faulty or misaligned thermistor.
|

- 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.

**Printing via USB is highly recommended for this.**

#### Configuration:
|

- Send `M603 L0 U0` to use manual loading & unloading.
|
||||
- Send `M603 L538 U555` to use automatic loading & unloading
|
||||
- The `L` and `U` paramters define the load and unload length in mm. The values above work well on a stock setup, if you modded your extruder, bowden tube or hotend, you might need to adjust those.

- Alternatively: Use `FilamentChange Pause` in the Special Menu
|
||||
- The nozzle will park and your printer will beep
|
||||
- Remove the filament from the bowden tube
|
||||
- Insert the new filament right up to the nozzle, just until a bit of plastic oozes out
|
||||
- Remove the excess filament from the nozzle with tweezers
