Fan control

Postby Eddi » Mon Jun 07, 2021 2:18 pm

why is it not possible to turn off fans that are not needed?
If I print only PLA types, why does the device fan (HEPA) have to run.
Also the extruder fan of the not used extruder runs without reason.
My second printer, the CloneR1, turns off the extruder fans when the temperature is below 50 ⁰C-.
It would be nice to be able to set this in the Ideamaker.

The HEPA filter is not only used for material odors but also small particles that can be produced while printing. For this reason, we recommend that it be in use at all times while the machine is printing.

Unfortunately, the extruder cooling fans are run off a 12v supply that can not be controlled via firmware/software. They are always running at 100% at all times to ensure that there are no heat creep issues when the hotend is heated.

Just have to wonder why there is such a big daylight air gap up the side of it in the filter housing that it does not work very effectively.

The HEPA filter fan air flow out of the machine creates a negative pressure within the machine which helps keep the particles near the gap within the machine.

REALLY !!!!!!!!

So the paticles somehow by magic resist being pulled through the path of least resistnce (the gap) between the filter and the fan, then wait until they can get through the filter instead.
