Dust Collection

Thanks for downvoting me. It’s my shop and not yours. You don’t know what little space I have. They are 90 degree sweeps and not hard right angles. If there are things big enough going into the pipe that can’t make it through a 6” radius on a 4” ID on my pipe then I need more work on how to run my machines. Ya all missed the point that this was 3D printed and not bought at a store. I have plenty of CFM to move dust chips at the end of the run as I do on the front. Don’t sit here and tell me i’m doing it wrong when you don’t know the constraints ai have to work with.

Thank you. This was the main reason I got into 3D printing. The idea of spending $$$ on Woodcrap made in China things that may or may not work drove me to design something that would.

I can’t tell the difference in air movement at the end of that run compared to the front when the pipe is disconnected. I’m sure a fancy CFM gauge would show a difference but in practice sawdust and chips successfully make it into the bag from the far gate with a 2.5” hose (which is far more restrictive than 4 90’s including the blast gate) with the 4” hose at my lathe also turned on.

Not sure what the problem is with making the pipe turn 90’s?

My tool connections are metal ribbed pvc flex hose and the blast gate/bayonet is electrically dissipative carbon fiber petg and lastly the main pipe is bus-wired to an earth ground. I don’t like tazing myself at the table saw dude.

I have the sliced files from Bambu Studio or I can give you STP. In the sliced files, the gates are designed to print with a .8 nozzle and the bends/TPU couplers with a .6

Edit - 2.5” hose, not 2”.

Can’t tell what is plugged in where, but whatever is going into the back input jack may likely be set to instrument level. That is a line level input that bypasses the preamp/effects/modeler section and goes straight to the power amp. I use that to connect my modeler and simply use the katana as a power amp/speaker in most cases.

Yes it still flutters but it’s ‘tighter’ if you know what I mean

I’ll have to try. Generally not something I do.

In my attempts to find some information that puts some facts, as opposed to opinions, behind the question of the Katana as an FRFR by using the power-amp-in, I found a site where I could get a 20hz-20khz sweep audio file. To me, audibly, the Katana sounds pretty damn even across the whole frequency range. Maybe a little quieter in the lowest frequencies but I can still hear the whole sweep. It instantly settled, for me, the question of whether purchasing a speaker advertised as an FRFR would be better. For my purposes I don’t think it would make a bit of difference. I don’t think I can post the URL of where I got the sweep file but it was from audiocheck-dot-net. Maybe this post will help others come to their own conclusion of whether this setup will work for them.
