No proper start codes after Slice (cura engine)

Who can help me.
I have problem with the SLICE (with cura engine).
The fan is no longer started.
The first objects which I printed were fine. The Gcode looked as follows.

G28
G1 Z5 F600
G1 Z0 F600
M106 S165
G90
M82
M104 T0 S210
G92 E0
M109 T0 S210
T0
M83
G1 E10 F100
M82
G92 E0
M117 Vertex is printing
G1 Z5 F1000
M106 S255
G0 X67.293 Y79.231 Z0.2 F10800
G0 X67.802 Y78.813
G1 X69.365 Y77.892 E0.04752 F900

But when I now an object Slice the ventlator will not start !!!
I have several times the program REPETIER HOST v1.0.6 reinstalled, but I always get when Slice’n example VERTEX_LOGO> STL Gcode the looks as following:

; Default start code
G28 ; Home extruder
G1 Z15 F600
M107 ; Turn off fan
G90 ; Absolute positioning
M82 ; Extruder in absolute mode
M190 S50
; Activate all used extruder
M104 T0 S210
G92 E0 ; Reset extruder position
; Wait for all used extruders to reach temperature
M109 T0 S210
;Layer count: 50
;LAYER:0
M107
G0 F9000 X82.989 Y87.993 Z0.300
;TYPE:SKIRT
G1 F1800 X93.763 Y77.218 E0.76020
G1 X94.188 Y76.867 E0.78770

Who knows what is going wrong?

Perhaps you’ve unchecked the “activate cooling” option.

3

Raby Thanks for your response but the “cooling” is activated.
Also strange that the code “bed heater M190 S50” is listed.

4

I kind of remember reading that the fan is disabled for the first layer.
This maybe for dual print head machines.

5

Look at the start G-code is the Cura settings. Is there anything changed? Your first one is the default one.

6

I’ve never made a change in the Cura start codes.
State one time in the start code “M107; Turn off fan” Why?
Moreover, nothing about bed heating: “M190 S50”
Maybe you want to publish you start codes?
Possibly I pass that on, and is it good.
Here my start codes.

; Default start code
G28 ; Home extruder
G1 Z15 F{Z_TRAVEL_SPEED}
M107 ; Turn off fan
G90 ; Absolute positioning
M82 ; Extruder in absolute mode
{IF_BED}M190 S{BED}
; Activate all used extruder
{IF_EXT0}M104 T0 S{TEMP0}
G92 E0 ; Reset extruder position
; Wait for all used extruders to reach temperature
{IF_EXT0}M109 T0 S{TEMP0}

Single head start g-code :

G28 ; Home extruder G1 Z5 F{Z_TRAVEL_SPEED} G1 Z0 F{Z_TRAVEL_SPEED} M106 S165 ; Turn on fan G90 ; Absolute positioning M82 ; Extruder in absolute mode ; Activate all used extruder {IF_EXT0}M104 T0 S{TEMP0} {IF_EXT1}M104 T1 S{TEMP1} G92 E0 ; Reset extruder position ; Wait for all used extruders to reach temperature {IF_EXT0}M109 T0 S{TEMP0} {IF_EXT1}M109 T1 S{TEMP1} {IF_EXT0}T0 {IF_EXT1}T1 M83 G1 E10 F100 M82 G92 E0 ; Reset extruder position M117 Vertex is printing G1 F1000 Z5

In your filament settings is there anything about the bed temperature <>0?

8

Are you using the correct config in the slicer settings before you press the slice button.

There was indeed a setting bed temperature at 50. This put to 0 and the code M190 S50 is not coming back.
The code M107 (fan out) came through the setting PRINT CONFIGURATION: VERTEX DUAL HEAD. This setting put to VERTEX SINGLE HEAD. Now comes after slice with CuraEngine code M107 anymore.

Thanks for all the support
