As part of the build process, the Sanit圜heck.h will print helpful error messages explaining what needs to be changed. To use configurations from an earlier version of Marlin, try dropping them into the newer Marlin and building. A variety of pre-built configurations are included in the Configurations repository to get you started. Simply edit or replace these files before building and uploading Marlin to the board. These two files contain all of Marlin’s build-time configuration options. Configuration_adv.h serves up more detailed customization options, add-ons, experimental features, and other esoterica.Configuration.h contains the core settings for the hardware, language and controller selection, and settings for the most common features and components.Marlin is a huge C++ program composed of many files, but here we’ll only be talking about the two files that contain all of Marlin’s compile-time configuration options: M306: Model predictive temperature control.Intel specification for a 4 pin fan connector Although this page is related to the 3 pin connector, the 4 pin reference document used the same pinout for the first three pins.The following picture of a 4 pin connector serves only as reference for the pinout numbering. The 3 pin connector is recommended for carrierboard designs. So, in the end the fan can be plugged and is working. In order to assure compatibility with consumer PC market fans the connector itself was assembled 180° turned. Design Guide for ETXexpress Carrier Boards Rev.Unfortunately the pinout in the schematic of the following carrierboards and documents is wrong:
(The 3 pin connector has been used, not the 4 pin connector) Due to easy available fans on the consumer PC market the same connector has been used. Woodpecker and Robin baseboards may implement a fan connector.
