I mounted my Duet without a steel enclosure February 20, 2016 03:10AM |
My printer is offline at the moment while I wait for a new hotend, so in the meantime, I thought I would address the problem of my power supply and Duet being ziptied to cardboard on the side of my desk. It's taken me a couple of weeks to arrive at this point, and I'm happy with how it turned out. Given the scarcity of the stainless steel enclosure, I thought I would share my build in the hopes that it helps someone else who can't get their hands on one!
Look ma! No steel enclosure! Definitely not CE compliant... sorry
Two 5mm boards, cut with a halflap joint and screwed into the existing power supply holes. The power supply is mounted to the printer with a lasercut acrylic spacer, as per the Ormerod 2 documentation.
I've separated my AC connection from DC with an HDPE sheet I've ironed into shape from a used milk jug. This replaces the printed AC cover until I can print something better.
@dmould supplied me with the PSU brace. It's held in place with a printed M4 T-nut, which is the only thing I've printed successfully!
The IEC hole is 50mm x 30.5mm, cut 5mm from the bottom corner. The Duet is mounted to the wood using 4x 3+15 hexagonal standoffs. The two boards are hardboard 5mm thick. One board is 12 x 17cm. The other board is 7.5 x 17cm. The two grooves were cut 5mm from the edge, halfway down and up each respective board. The result is a corner joint held in place by friction - no screws. From there, it's relatively easy to screw four holes in from the back, and mount your hexagonal bolts to it. I used M3x8mm for both ends of the hex standoffs - accounting for the thickness of the board, there should be plenty of space remaining inside the hex to attach the Duet. So far, I've noticed that the orientation of the Duet is somewhat important - the one that works the best for me is having the LAN, USB, and SD connections down in the bottom right.
I originally wanted to do the entire thing from HDPE plastic that I've scavenged from 3 litre milk jugs, but it's a really fickle material to work with. It cuts really easily and is really sturdy (especially if you can fuse several sheets together), but it warps like crazy once it cools. A clothing iron works wonders smoothing it out and folding to a crease. Not sure of the precise melting temperature, but you'll get a good crease somewhere between "synthetic", "silk" and "wool"!
Overall, I'm really happy with how this turned out. I've reclaimed some space on my work desk, and my cabling should be much tidier now that I have fixed lengths to work with! Since mounting the supply to the printer, I've noticed at it's actually much sturdier... it no longer rotates very easily about the Z axis now that there's some weight attached to it. Now to get my spool mount attached!

I'm still working on my enclosure. Heres what i got so far:
I am hoping to just use M3x50mm screws on the bottom of the metal plate of the old Duet 0.6 and just slide the entire thing on them and securing with nuts(probably gona print something so i can unscrew it by hand).
BTW DC why did they put screw terminals for the hot end on duet 0.8.5? wasnt the standard connection(molex? dont remember name) like on duet 0.6 good anaugh? I am waiting for crimping tool to arive so i can install the new duet.
And a tip: check the USB solder ,mine isnt soldered well....
