Creality Print 6.3 & Creality Print 7.0
With my Creality K2, I am using my Side Auxiliary Fan to move air round the enclosure during heating.
I turn the cooling feature off selecting side fan 0%
I then turn the fan on manually in Fluidd or use a modified gcode gcode_macro M141
The side fan runs then turns off.
I inspected the print gcode and Creality Print is adding “M106 P2 S0” in three places, this turns the side fan off.
This occurrence is not a problem as I turn the side fan on after this.
-----------------------
First addition
; EXECUTABLE_BLOCK_START
EXCLUDE_OBJECT_DEFINE NAME=50mm_Fan_Cradle.stl_id_0_copy_0 CENTER=130,130 POLYGON=[[76,185.4],[97,65],[163,65],[184,185.4],[184,195],[76,195],[76,185.4]]
M73 P0 R52
M106 S0
M106 P2 S0
----------------------------
This is a problem as the print has started
-----------------------
Second addition
;TIME_ELAPSED:996.099609
M106 P2 S0
;LAYER_CHANGE
-------------------------
This occurrence is not a problem as it is at the end of the print and I turn the side fan off after this.
--------------------
Third addition
EXCLUDE_OBJECT_END NAME=50mm_Fan_Cradle.stl_id_0_copy_0
M106 S0
M106 P2 S0
;TYPE:Custom
; filament end gcode
END_PRINT
----------------------
With the side fan deselected there should be no occurrences of M106 P2 S0
This looks like it is a reoccurrence of a problem in an old closed post with Creality Print 5
https://forum.creality.com/t/auxiliary-fan-switches-on-and-then-switches-off-again/14190
In my print gcode I am having to edit the “M106 P2 S0” out in notepad.
-------------------------------------
I apologise, I didn’t understand the software, I have been trying to sort this for over a week.
To stop the fans turning off in addition to selecting Side Fan Should 0%
You also need to set Auxiliary Fan Opening Height to your maximum build height, in my case 260mm
This prevents the Creality Print is adding “M106 P2 S0” in the middle of the print
I hope Somone will find this useful in the future
