Known Issues

Please report any issues with tool change, special extruders, dual X axis, and SCARA.

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
With this option Cartesian moves are broken into small segments when a mesh-based bed leveling system is enabled.
#8658 : Split first move to planner for better chaining
This change fixes the dreaded "first move stutter" that Marlin inherited from Grbl long ago.
#8690 : Purge remaining blocks on endstop/probe hit
This change prevents any extra moves left in the planner from running after a quick-stop.
#8697 : Alter jerk code to address COREXY stuttering
There are many ways to handle "jerk" (and we've tried a few). The latest iteration fixes a Core stuttering issue while reducing the jerk code to its essence.
