Duex5 Testers
-
UPDATE 2: I have emailed those who expressed interest. If you don't have the email then let me know (info@duet3d.com).
-
If I'm not too late I'd love to get in on the fun!
-
I didnt get it Tony…? (no email)
-
UPDATE 3: I have received a lot of emails, thank you all for your responses, I have not had time to email back to you all individualy yet. I will collate the list this afternoon and email an update then.
-
Please count me in as well.
-
UPDATE 4: Thanks for everyone who has now responded. We will start sending out the paypal invoices today but as there is a lot going on we might not get them all out for a couple of days.
When you receive yours please pay promptly as we do have a reserve list.
-
Is there still room to get on the list?
-
@Qanelin - I am running a reserve list in case anyone changes their mind
-
I would like to be added then (as long it is ok being in the US). I recently purchased the DuetWifi and my printer has the diamond hotend so I need 3 extruder capabilities.
-
Tony,
Did you send out the Paypal invoices yet? I haven't received it yet but I did get the email saying I was one of the ones selected.I'm really looking forward to getting a hold of the new board, lots of plans for it.
-
We are always ready to test things out!

For anyone that's interested, I've designed an enclosure that will take the Duet Wifi plus Duex expansion board and put it on Thingiverse. http://www.thingiverse.com/thing:1859048
It takes the two boards but with them mounted one above the other, as if they were mounted back to back and joined at the Vin connector but then opened out like a book. It takes two 80mm fans internally to blow air on to the back of the boards and exhaust through slots top and bottom. I included the OpenScad file so feel free to play around with it. Warning - it's 290mm x 140mm so you'll need a biggish build plate.
Edit. If you mount the boards this way, you might need a longer ribbon cable and with a twist in it.

Looks really neat!
How is the airflow if the fans suck air through? I find less turbulence and the temps in the enclosure lower.

The fans suck from the back of the enclosure and blow onto the underside of the boards, then the hot air exhausts through the slots in the top and bottom of the enclosure (if you fit the fans the right way round that is). I fit fine mesh grills on the fans to keep the dust out. For info, I stuck a thermistor onto one of the XY stepper chips and created a dummy tool so that I could monitor the temperature on DWC. I've set the fans to thermostatic mode and have the temperature set to 45deg C. At idle, with steppers at low holding torque, the drivers run at about 39 deg C on my printer so the fans are off. When it starts to print, the temperature goes up to 45 but never more than a fraction of a degree above this as the fans do their job. I believe DC42 is likely to add an update to the firmware at some point in the future which will mean that the thermistor isn't necessary.

Ok great. I printed this enclosure off overnight!

Just added another pic to Thingiverse that shows the fans mounted in the enclosure.
I'm just a tad concerned that I haven't left enough room between the 2 boards which might make it a bit awkward to connect Vin to both. There won't be enough room to use ferrules on the wires for both boards that's for sure. I'm planning on using a solid conductor between the boards so I reckon it'll be OK but won't know for sure until I get my paws on a Duex5. There is room in the outer part of the case to move the Duex down a bit if necessary so the overall size wont need changing, nor will the lid.

For info the Duex2/5 pinout and wiring diagram is up here:

UPDATE 5: We have received all the prototype boards from the manufacturer, built the test rig, and managed to get the first few tested today
The first boards will be dispatched Monday, with the remainder following on Tuesday (less any that fail testing which need to be reworked). You will receive a notification by email once your board has been dispatched on Monday or Tuesday.
