Simplify3D fan is turned on before tower #35

Open spegelius opened 6 years ago

spegelius commented 6 years ago

On some cases, like when printing ABS, Simplify3D turns the fan on for some reason and this happens just before tool change -> tower gets cooling -> warping

wbarber69 commented 6 years ago

perhaps its because of differences in nozzle temp on the gcode?

spegelius commented 6 years ago

No, the models I've been printing all use same temp on the nozzle. It's probably related to the extra cooling on fast layers-feature. I've seen this before, S3D likes to turn the fan on and off somewhat irregularly. Doesn't matter with PLA, but with ABS it's a real problem. I've tuned to fast layer time down to 1 seconds or so, but it still does this occasionally... Compare to Prusa Slic3r, when fan setting is off, it stays off.
