1.11 - no way to keep fan from coming on when printing ABS #1910

Closed rsilvers129 closed 8 years ago

rsilvers129 commented 10 years ago

I never want the cooling fan to come on when printing ABS, but I do want "autocooling" to slow down the print speed for faster layers.

I would like a check box to keep the layer-speed auto-cooling on without having the fan come on ("never use cooling fan (ABS mode)")

Perhaps a higher level configurator could do something like this, or slic3r simple mode could have some presets for different plastic types, perhaps?

If you're using "expert mode", I think there's a bunch of ways to disable the fans while still slowing down. Set "Enable fan if print time is below" to 0, or set "Disable fan for the first X layers" to 9999, or set both min and max fan speed to 0, and I guess you won't have any fan on.

I don't think hard coding options for each type of plastic is a good idea at the basic level, because you'd only get yet another option that does the same thing, and then everyone with a new type of plastic will want an option for their defaults too. :-)

@rsilvers129, @kefir- is right: set Max Fan Speed to 0% and you'll be okay.

Maybe the Keep Fan Always On option should be changed to Enable Fan with three options: Always, Never, Auto. Comments?

Always on, always off, and a configurable Auto would be good.

The help text could mention that PLA is generally best with the fan always on, and ABS is generally best with the fan always off. I had a friend who was cracking his ABS and it was because he noticed that the ABS profile that I sent him had the fan off, so he turned it on.

Set max fan to 0%. Active cooling on ABS is something of an art form though, you can get away with a lot more of it in a heated enclosure.

Closing.
