==== Maintenance ====
  * [[:lubrication|3D Printer Lubrication]]

==== Custom Main Motherboard Firmware ====
Using the custom community firmware for the main motherboard has many benefits... it makes your printer quieter and more accurate and reliable in several ways.
  * **[[a5:firmware|See this page for information on upgrading the firmware]]**
  * **[[a5:bootloader|See this page if you've lost your bootloader and can't flash]]**
  * **[[a5:factory-firmware|See this page for details on restoring back to factory firmware]]**

==== Custom LCD Board Firmware ====
The touchscreen LCD module (MKS-TFT28 v1.3) on the A5/A3S is separate from the main motherboard, and runs its own firmware. It also has a community firmware available that adds some additional features. 
  * **See [[a5:lcd-firmware|this page]] for info on upgrading your LCD firmware.**
