G-code substitutions run after Print remaining times

[Lecso11]

What happened?

I wanted to replace the M117 Time Left 0h3m53s line with a line such as _MYMACRO R=0h3m53s so I could pass the time as a variable, but the Gcode substitutions might run before SS adds the M117 lines, and that results in no change in my code, since it can't find those lines.

Project file & How to reproduce

OpenLOCK-Clip-v5.3.zip Enable Print remaining times with M117 Enter a Gcode substitution for M117 Time Left and replace it with R= The resulting gcode does not have the M117 lines changed.

Version

2.4.58.2

Operating system

Windows 10

Printer model

Voron 2.4 with klipper

Its my understanding that the M117 remaining times are produced by a post processor, that means it has to have the gcode done before it can produce them.

I dont know how feasible it is to control the ordering of any /all of these various post processing options that we seem to have now though. Have to wait for Merill on that one.

I guess what you have to do for now is to create a post-process script that replace M117 (.*) by MY_MACRO R=$1

I won't change the behavior of the gcode replace current alog in the near future, as I already ahve a bit too much thing to change.

mmm... I guess i can re-apply it at the end. I'll see if it's easy enough.

A workaround is to call sed in post processing script. (It's available on Linux. Need to find alternative on Windows)

I use this post-processing script to turn off bed heating 4 minutes before printing finish:

/usr/local/bin/sed -i 's/M117 Time Left 0h4m0s/M140 S0/';
