Fan on/off issue at slicing

[drayson 74]

Hi there,

yesterday I had a very strange situation...

I sliced and started printing this helmet mount for my action cam

http://www.thingiverse.com/thing:22212

with following setup:

0.15 layer hight

infill 20%

support everywhere

support values in x/y/z modified, but not available any more (something like x/y 1.5, z 0.1 fill 20%)

During print I recognized because of very ugly layers that the fan has been disabled. enabled it manually, I recognized a few minutes later that it has been switched off again...

Print aborted, what a mess...

I checked the gcode and it seems that cura placed an M107 command every time, the support starts to fill the strap holes in the part - so 3 times off. There was a M106 too but only a few lines before M107.

Next, I sliced the part again with modified support values and checked the gcode again... now, everything was ok - M106 instead of M107...

Unfortunaltey I overwrote the initial gcode accidentially so I can´t post it here.

I just wanted to document this issue in case somebody else has the same.

@ Daid, maybe a bug... sorry for not providing more info :-(
