config-user.g overwritten with config.g contents

[gnydick]

I don't know what happened, but things started acting funny, I checked and my config-user.g file now has older contents of config.g. This isn't manual error. I've not done any renaming, full copy & paste, etc. I literally just homed my machine 20 minutes ago, and now it doesn't work because there is no more probe defined as it was in config-user.g.

So now I've lost my lead screw positions, mesh config, z probe, etc.

I'm on 3.5.3 + SBC, duet 6HC

@gnydick AFAIK config-user.g is not a system generated/modified file (unlike, say config-override.g). I can't see a mechanism that would lead to it be replaced with an older version automatically.

As an aside I have seen config-user.g mentioned once or twice in config.g files. Do you know what the provence of doing it that way is?

[gnydick]

@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
