1.1.9

Marlin 1.1.9 is the final 8-bit flat version of this firmware, and the last 1.1.x release. A monumental amount of talent and effort has gone into its production. Throughout Marlin 1.1 development we worked closely with the community, contributors, vendors, host developers, library developers, etc. to improve the quality, configurability, and compatibility of Marlin Firmware, while supporting a wide variety of Arduino-based boards.

For this development cycle we aimed to address bugs and overhaul the motion planner. The end result is a much smarter and more robust motion system, and this should be noticeable as improved print results and reduced print job times.

Change Log

New Features

• Specify stepper drivers per-axis. Marlin determines pulse timing.
• Updated to Linear Advance 1.5 (with new K value range)
• Added POWER_LOSS_RECOVERY for SD printing (based on work by Creality3D)
• Added POWER_LOSS_PIN to detect power loss early and save state
• Added Z_CLEARANCE_MULTI_PROBE to set probe "bump" distance
• Added DELTA_FEEDRATE_SCALING to dynamically scale the feedrate for correct delta motion
• Added a Lightweight Status Screen LIGHTWEIGHT_UI for ST7920 (most graphical displays!)
• Added homing / leveling / probing options
• Added M701 / M702 filament load / unload
• Added SLIM_LCD_MENUS for reduced build size
• Added AUTO_POWER_CONTROL to turn power on/off as needed
• Added M421 N parameter to set a mesh point to NAN
• Added support for Malyan LCD

Fixed and Optimized

1.1.7

We've had one of the most active periods ever, with over 125 pull requests and 450 commits, representing dozens of evolutionary improvements. The 1.1.7 release contains bug-fixes, enhancements, refinements, new features, and other changes aimed at improving stability and addressing outstanding issues.

Known Issues

Major Changes

• #8229, #8381 : Operate in Native Machine Space
  Marlin now operates internally in native workspace, which simplifies and optimizes the movement code.
• #8458 : No retroactive adjustment with M851 Z
  Version 1.1.6 incorrectly modifies the BILINEAR mesh in response to M851 Z. This has been fixed!
• #8596, #8636 : Add SEGMENT_LEVELED_MOVES for MBL, Bilinear, UBL
