Rename M117 macro

General Discussion
1

Is it possible to rename the M117 macro using “RENAME_EXISTING” ?

If I try to rename I got an error message “rename of different type”

I would like to enhance this macro to send the text also to the console like that:

[gcode_macro M117]
rename_existing: ORIGINAL_M117
description: displays message on the LCD and the console simultaneously
gcode:
ORIGINAL_M117 { params }
{% if params != “” %}
RESPOND PREFIX=“info” MSG="{ params }"
{% endif %}

Rename it to something of the same format like M117.0 or M999 …

I’m not sure this is possible, at least not without a way to parse the “traditional” (M117) params; with the override I get

// Unknown command:"M117.1 {'"info {'M': '117', 'PRIMING': ''}
// Unknown command:"M117.1 {'"info {'M': '117'}
!! Malformed command 'RESPOND PREFIX=info MSG="{'Z': ', #0', 'M': '117 0.2'}"'

The last one’s an error that aborts the print. Basically, serialization of the params dict is insufficient, and the dict is structured poorly for access by a macro.

Yeah - M117 is handled in a special way because it is unlike other g-code commands. So, I don’t know of a good way to rename it.

It should be possible to make your own “extended g-code” macro and call M117 from it though.

M118, too, right? Are there any others that use this special parsing?

M118 doesn’t have special handling today. The commands with special handling are in cmd_default() in klippy/gcode.py .
