M190 S55 in my gcode file

Recommended Posts

Posted · M190 S55 in my gcode file

Hi,

in Cura 2.5.0, in the printer configuration, in "initial gcode" we see this:

G21 ;metric values

G90 ;absolute positioning

M82 ;set extruder to absolute mode

M107 ;start with the fan off

G28 X0 Y0 ;move X/Y to min endstops

G28 Z0 ;move Z to min endstops

...

But in my generated gcode file i can see this:

;FLAVOR:RepRap

;TIME:43839

;Filament used: 41.4211m

;Layer height: 0.2

;Generated with Cura_SteamEngine 2.5.0

M190 S55

M104 S198

M109 S198

G21 ;metric values

G90 ;absolute positioning

M82 ;set extruder to absolute mode

M107 ;start with the fan off

G28 X0 Y0 ;move X/Y to min endstops

G28 Z0 ;move Z to min endstops

...

With the code "M190 S55", the printer "Wait for bed temperature to reach target temp".

In the previus version of Cura, i generated files with this start:

M140 S60.000000

M109 T0 S198.000000

T0

M190 S60.000000

;Sliced at: Wed 08-03-2017 21:38:28

;Basic settings: Layer height: 0.2 Walls: 1.6 Fill: 30

;Print time: #P_TIME#

;Filament used: #F_AMNT#m #F_WGHT#g

;Filament cost: #F_COST#

;M190 S60 ;Uncomment to add your own bed temperature line

;M109 S198 ;Uncomment to add your own temperature line

G21 ;metric values

G90 ;absolute positioning

M107 ;start with the fan off

G28 X0 Y0 ;move X/Y to min endstops

With code "M140 S60.000000", the printer heats the extruder at the same time as the bed (Bed Temperature (Fast)).

Can I change de real initial code and put M140 instead of M190?

Thank you.

Regards
