@T3P3Tony I can understand the thoughts on config-user.g not being a system file, so I'm guessing it was a DWC bug.
The config-user.g is good for settings you may want to frequently tweak after boot, that are safe to reload at any time. Having a reload_config-user macro usually accompanies it. I personally have a number of additional files
axis-limits.g: I have kinematics that get tweaked frequently so i will reload that
tools.g: this sets all of the kinematic configs for the tools.
macros/tfree|tpre|tpost: these have all of the common movements for all of the tools. these macros take parameters so any movement lengths only need to be provided in the tfree_.g, tpre_.g, and tpost_.g files, like `M98 P"/macros/tools/tfree.g"
It took me a lot of work to get this all working smoothly. But now I have a lot of safety measures built in with docking sensors, "coupler homed?", temperature thresholds.
Examples
tfree0.g
; tfree0.g
; Common routine
M98 P"/macros/tools/tfree" X3.0 Y20.0 ; X param is how far from the end of X axis to go to pick up the tool , Y param is absolute Y position to pick up the tool
tpre0.g
; tpre0.g
M98 P"/macros/tools/tpre" X3.0 Y20.0 ; move into position, same params as tfree
tpost0.g
; tpost0.g
M98 P"/macros/tools/tpost" A0.037 ; A param is pressure advance setting
M593 P"zvddd" F52.8 S.1 ; enable input shaping
and the macros they call
