Show me your duet 3 enclosures!

Finally posted my enclosure on
Thingiverse, I’ll be making further refinements but it’s mostly there, I’m really happy how the logo came out, any suggestions I’m happy to hear them
https://www.thingiverse.com/thing:4307535#edit I have unfortunately had to close my account on thingiverse due to the recent hacking etc I’ll attach the latest STLs to this post soon for those who want them

@CCS86 I presume that PSU is heavily modified? The fans tend to exhaust in that location and you've got the fan blowing in?
-
@CCS86 ...but since you suck (
) you could consider adding fan filters so dust doesn't clog up the back side of the duet. Nice fan ducting though, food for thought! -
That's not a duet3
... pretty nice looking enclosure anyway. I was debating between plywood and acrylic for my baseplate. -

It isn't modified besides the fan replacement. The original fan also blew into the power supply like this, but it was loud. Most axial fans are setup to blow through, not pull.

But the same concept applies, regardless of the board.

@CCS86 there's no pattern to it. I've got your power supply and indeed it does suck in.
The 500W meanwell has a fan on the top edge that sucks out, and a 200W meanwell as well as a 350W no name suck in.

Not strictly speaking an enclosure, this is the back of a "Jubilee" tool changing printer:
-
Remixed a case for the Duet 2 that I found quite good. It provides ample natural cooling, cable access and the lid swings out of the way. Also includes mounts for a 92mm and 40mm fan, even though fans are not necessary if using typical NEMA 17 steppers.

You can't "suck in". It is "blowing in" regardless of whether the fan is mounted flush to the inside or outside of the enclosure.

@CCS86 you're being pedantic, I am merely indicating direction.
Anyhow whats the problem? I was merely saying even with one manufacturer the airflow direction isn't consistent. Hence my original confusion with the direction of your fan.

@gtj0 Impressive! Shielded stepper cables?
Planning to install a Pi once DSF is a little more stable. Curious what pins you connected from the D3 to the Pi. Interested in only using what’s necessary and leaving the rest for future GPIO.
PS Your bearing block on the Z lead screw is a great idea. Might have to steal that one

@mwolter check out the schematics. The required connections are listed there. If you supply an isolated external 5v (negating need for the +5V cores) to the Pi I'm not sure if it would be possible to save on a few of the negative connections too.
Edit: if you do use an external supply for the pi ensure the dc negative isn't directly linked to earth as you could set up an earth loop with considerable current if your main psu is earth tied.

earth loop
drew up an isolator (back in January) but haven't had a chance to test it (nor decided weather to add a 3.3v ldo instead of a 3.3v header)
suppose could create a new topic to discuss if there is interest. (edit, changed to ADuM1200BR to allow 10mbps, ISO7721DR seems to be pin compatible and i'll do a test with that)
Moved it to a a less personal EasyEDA account, https://easyeda.com/bearer/duet36hc-isolator -
@bearer nice work!
-
@bearer isn't 1200 "not for new designs" replaced with 120n ?
-

quite possibly, I just picked what jlcpcb could assemble today (initially the 1mbps part because it was in the basic selection)
i would suspect any new parts to be pin compatible so not something i put much thought into tbh.
-
@bearer yeah 120n is pin compatible upgrade

Yes. 2 pair 20ga STP

As @DocTrucker said, check out the schematic...
https://github.com/Duet3D/Duet3-Mainboard-6HC/blob/master/Duet3_Mainboard_v1.0/Duet3_MB_schematic_v1.0.pdf
I'd connect at least pins 20 and 25 for grounds. That keeps the pins needed in a group from 19-25.PS Your bearing block on the Z lead screw is a great idea. Might have to steal that one
Go for it!
