Documentation on how to use the {<name>}-variables in Cura 15.* G-Code?

Postby reibuehl » December 6th, 2016, 8:35 am

Hi all,

I am trying to write some custom start and end G-code to use my Fabrikator Mini with Cura. I tried to find out how the variables like {print_temperature} and {TEMP0} differ and tried to lookup that in the documentation but unfortunately the Help->Documentation in Cura 15.04.6 just points to https://ultimaker.com/en/resources/1871 ... er-manuals where I do not see any Cura manuals (anymore?).
Can somebody here explain me how these variables work, what ones are available and especially what the difference between {print_temperature} and {TEMP0} is? ;-)

You can look at the source here...

It extends the string Formatter class to parse the start/end GCode and replace any Cura parameter found in it.

It passes the complete settings dictionary to the formatter (see _buildGlobalSettingsMessage()) so it looks like there are a gazillion possibilities ;)
It would be good to have indeed the most common ones documented.

But a good start is to look at the DictionaryOfDoom (in the default dict) -- that should give you all you need.

Re. the TEMP0, ... variables (all the ones in capital) I think they are coming from old Legacy Cura.

Has this functionality - the variables - been removed from Cura 2.x? I just tried to setup the printer in Cura 2.3.1 with the same start and end g-code as in 15.04.1, but the resulting g-code contains the variables and not the values:

Code: Select all

;FLAVOR:RepRap
;TIME:6446
;Generated with Cura_SteamEngine 2.3.1
M190 S60
M104 S200
M109 S200
G28 ; Home extruder
G1 Z15 F{Z_TRAVEL_SPEED}
M107 ; Turn off fan
G90 ; Absolute positioning
M82 ; Extruder in absolute mode
M140 S70 ; turn on bed heater
M190 S70 ; wait for bed to heat
; Activate all used extruder
{IF_EXT0}M104 T0 S{print_temperature}
G92 E0 ; Reset extruder position
; Wait for all used extruders to reach temperature
{IF_EXT0}M109 T0 S{print_temperature}
