"Linear Advance" Release - 119r11

Quick Start   Wiki Pages  

The firmware now includes Marlin's "Linear Advance 1.5" feature!

IMPORTANT, IMPORTANT, IMPORTANT!

The format of the saved settings has changed with this release. After installing the firmware, it is imperative to restore the factory settings. Simply use the command M502_FACTORY.gcode followed by the command M500_SAVE.gcode from the contents of the micro SD card.

Please note: when installing or upgrading, the firmware may not properly detect and correct errors in the flash memory used to store its settings. Bizarre or erratic motion is a strong indication that there is a problem with the settings. The M502 (load factory settings) command followed by the M500 (save settings) command should get the firmware operating from a known "ground" state.

Notable changes

  • The firmware now includes Marlin's "Linear Advance" feature. As the feature requires some individual calibration and tinkering, it is disabled by default. (see "Linear Advance 1.5")

  • The Marlin "kill" process now reboots the printer without executing the bootloader. This change avoids some issues with the bootloader.

  • A small change in AUTO_CALIBRATE.gcode; don't adjust the tower angles with the G33 command. With this change, the calibration process will NOT override a user's custom M665 "trim" values.
