Fan control algorithm? Fan is at 50% until layer 45

TT_Vert

No idea where this comes from.  I have min fan temp at 50 and max at 100. My fan can, and does, handle PWM just fine.  The only time it's at 100% is at layer 349 of 357.  For all intents and purposes it's at full (S204 or greater) at layer 45 but can this be defined somewhere?  I don't see an option to do so.  I've included the cura slicer generated M106 commands and corresponding layer for info.

layer0 fan off layer1: 127 layer45 204 layer46 221 layer47 226 layer48 229 layer49 239 layer50 234 layer51 239 layer52 234 layer67 239 layer323 224 layer324 209 layer325 201 layer326 196 layer327 191 layer328 188 layer331 193 layer332 198 layer333 201 layer334 206 layer336 209 layer337 214 layer338 219 layer339 216 layer340 229 layer314 232 layer343 237 layer344 239 layer345 242 layer346 247 layer347 249 layer348 252 layer349 255 357 total layers

Thanks,

Fan speed depends normally on layer printing time. Longer times = lower speed. But that is slicer dependent which we do not program.

Ahh that makes sense and does correspond w/ quicker layers.  So you just embed cura into your software and don't touch the slicing at all?  Cura 15.x standalone doesn't seem to function like that which confused me.

Yes, we set a config file to curaengine and all generated comes form the engine.
