Cura not replacing tokens when TinyG code is included in start script

Recommended Posts

Posted · Cura not replacing tokens when TinyG code is included in start script

Hello!

I have a printrbot simple with the new G2 board (32bit TinyG board). This board requires some TinyG commands to be run BEFORE heating up the heatbed (to enable the heat bed). The problem is that the TinyG command to enable the heatbed seems to break the token replacement code in Cura. Here is a snippet of my start script:

M100.1 ({he3e:t})
M140 S{material_bed_temperature}
M104 S{material_print_temperature}
M109 S{material_print_temperature}
M100.1 ({{g55z:-3.2}}) ;Z-probe offset
G21 ;metric values
G90 ;absolute positioning

and here is the resulting GCode:

;FLAVOR:Marlin
;TIME:1995
;Filament used: 1.38607m
;Layer height: 0.1
;Generated with Cura_SteamEngine 2.7.0
M100.1 ({he3e:t})
M140 S{material_bed_temperature}
M104 S{material_print_temperature}
M109 S{material_print_temperature}
M100.1 ({{g55z:-3.2}}) ;Z-probe offset
G21 ;metric values
G90 ;absolute positioning

Now here is the generated GCode if I remove

M100.1 ({he3e:t})

from the start script:

;FLAVOR:Marlin
;TIME:1995
;Filament used: 1.38607m
;Layer height: 0.1
;Generated with Cura_SteamEngine 2.7.0
M140 S60
M104 S200
M109 S200
M100.1 ({g55z:-3.2}) ;Z-probe offset
G21 ;metric values
G90 ;absolute positioning

Seems pretty clear - I'm betting the curly brackets are throwing off the GCode parser. Hopefully this gets fixed soon because I have to manually edit my generated gcode files in order to print.
