This command causes Marlin to output a string like this:

FIRMWARE_NAME:Marlin 1.1.0 (Github) SOURCE_CODE_URL:https://github.com/MarlinFirmware/Marlin PROTOCOL_VERSION:1.0 MACHINE_TYPE:RepRap EXTRUDER_COUNT:1 UUID:cede2a2f-41a2-4748-9b12-c55c62f367ff

When EXTENDED_CAPABILITIES_REPORT is enabled, Marlin also reports its capabilities:

Cap:EEPROM:1
Cap:AUTOREPORT_TEMP:1
Cap:PROGRESS:0
Cap:AUTOLEVEL:1
Cap:Z_PROBE:1
Cap:SOFTWARE_POWER:0
Cap:TOGGLE_LIGHTS:0
Cap:EMERGENCY_PARSER:1

Hosts use this information to improve interoperability, so it's a good feature to enable.

With EXTENDED_CAPABILITIES_REPORT and M115_GEOMETRY_REPORT enabled, Marlin will also report detailed printer geometry:

area:{full:{min:{x:0,y:0,z:0,i:0,j:0,k:0,u:0,v:0,w:0},max:{x:200,y:200,z:200,i:0,j:0,k:0,u:0,v:0,w:0}},work:{min:{x:0,y:0,z:0,i:0,j:0,k:0},max:{x:200,y:200,z:200,i:0,j:0,k:0,u:0,v:0,w:0}}}

Coordinates are only reported for declared linear axes. So for a classic cartesian printer, the geometry report will look like:

area:{full:{min:{x:0,y:0,z:0},max:{x:200,y:200,z:200}},work:{min:{x:0,y:0,z:0},max:{x:200,y:200,z:200}}}
