 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.

 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.

 - 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.**

 - 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.
