Fan guards

Post by PcS » Tue Jul 28, 2015 3:14 am

I replaced my extruder and bed fan and just opted to not put the fan guards back on. I can now print any filament I have at at least 100 mms. For my setup petg used to be 50 mms. I think the increased airflow helps keep heat from creeping up the filament. I was seeing a lot of jams where the filament doubled over itself. PetG at that speed is awesome !!!

The best time to make "Fan Modifications" is midway through a 12 hour print btw. it's been proven by science.

On a side note the fans are not as loud either.

I replaced most of my fan guards with wire-metal ones, and all of my bed fans are guardless. I break fans just as frequently (and the filament drive fans always fail from bearings, not carelessness). Maybe that's why I've been successfully printing at 100-120mm/sec?

What fans are you guys replacing them with?

If the CFM is at least the same as the stock fans and they are quieter, that seems like a win all around.

I just bought a bunch of 40mm wire guards off of Amazon, they were more or less sold by the pound.

I've got like 2 dozen ... how many do you want? :p
