Can't get rid of M107 on Layer 0

Posted · Can't get rid of M107 on Layer 0

Does anybody know how to get rid of the M107 command on layer 0 of the gcode? My starting gcode sets M106 S255 because my fan is for the heat sink on the hot end. The fan comes on but as soon as it starts printing, the M107 shuts it off.

The only workaround I can find is to edit the file by hand.

Maybe I'm just missing a setting somewhere????

    Oh right. Yeah, thats intended behavior. The M107 2 is because you want the first layer to be cooled somewhat (hence the 2). If you deselect the 'enable cooling fan' in the advanced settings, this should no longer be added.

    Ahh, thanks, that did the trick. I had the "enable cooling" unchecked so it was generating M107. Enabling cooling and setting fan full on at height = 0 adds M106 S255.

    I guess adding fan settings in the start-gcode is pointless since they just get overridden no matter what...

    I just took out the M107 from the start G-code factor.

    This may effect bed adhesion but I print on blue tape with a brim so adhesion isn't a problem with PLA.

    Without a fan at all, PLA tends to swell in the feed tube and stop feeding. Heat creep issue I guess.
