Announcement: Duet 3 Toolboard revision v1.1
-
Hey Guys,
Hope you are doing well.
Any chances that I can get the schematic and PCB of the new Version?
Thank you in advance. -
So I need a Toolboard to finish a current build now. Which reseller in EU is supposed to receive 1.1 stock shortly?
-
@kipk
I have reserved one at
https://www.dold-mechatronik.de/They expect it to be in stock next week.
-
@fotomas thanks for the tip
-
@pixelpieper looks great , but what about the orientation of the accelerometer?
-

@lbi we looked at that but, as you can see, there is not a lot of space left!
Every board has two sides.
-
@zapta true. in this case we need to keep the board manufacturable at a reasonable cost and also thin enough to fit on a hermera tool on a toolchanger
-
@martin7404 its a 3d-accelerometer, you can adjust the orientation in software.

@t3p3tony, that's correct, good engineering is about striking the right balance.
BTW, I appreciate the density of your designs. I presume this one is also with Kicad. I played with much simpler design and know how much effort it takes.
-
A small wish (and with please ) :
In the next iteration, maybe already the next board-run(?), please consider reviewing if you can add in also the through-hole-solderpads for the stepper-motor-out
(guess I am one of the few that are no "crimp-ist", push-in would be favourite, otherwise will stick to screw-in-terminals )Best regards
-
Push in is very nice, but expensive compared to crimp connectors, and quite large - I haven't seen any with less than 2.5mm pitch and they tend to be quite high.

Thanks so much for answering! Yep most I found in some webshops were too expensive/big/... for now, but I just wanna try something other then crimping, maybe I stick with solder-in-screwin-terminals in the end... Guess I am on some sort of a quest there if you provide me the 4 additional motor-throughhole-solderpads, I will see what I get and will post it in the forum I guess my talent for crimping is just not really there
-
@lbi do you have a proper crimp tool?
I hate crimping, but once done it makes disconnecting and reconnecting wires much quicker than using screw terminals.
-
Are there any parts for crimping bundled with the toolboard (like duetboard)?
-
@fotomas yes there is a connector pack with the board
-
@fotomas I did received mine from dold
And it working great.
For now I tested only accelerometer as far I am building new large 3d printer. It took 15 minutes to crimp wiring, solder the 120 ohm bridge and run. -

At least I am not alone in the universe with that issue yeah of course you have a point, I know I can force myself to do it, just the outcome is appropriate to my feeling while doing it, I can borrow a tool at work, but some of them work even better when "crimped" by hand with a tiny plier... Ah for now I crimp, it is alright. Just would be great in the future to have the possiblity maybe to even order them with no connnectors soldered and buy either a screw-in or a crimp-connector kit and just solder it there, and for that the 4 through-hole-pads for the motor are missing. I know this would be / is for advanced users... but my solder-skills are actually not as bad as my crimp-skills are. Didnยดt want to bother all of you. It is allright. Keep up your work!
Best regards

@T3P3Tony
Is there a rough estimate when the product will be available again in germany ? -
@diy-o-sphere there is another batch currently undergoing testing, so I don't think it will be long.
-
Nice work, great to see that you listen to customer feedback.
Some feedback/questions from my end:
-
I do like the crimped connectors, but nice to see that the holes are still there for people preferring screw terminals. A suggestion for a future revision would be to align these holes so that one solid row of screw terminals can be mounted instead of separate sets. This makes the terminals a lot more sturdy and one would be less likely to damage pads or connectors if using too much force fastening the wires.
-
As a v1.0 owner, I'm a tad sad to see I'm missing out on all the accelerator fun.
Therefore the question whether I (being familiar with patching hardware, soldering and epoxy) would somehow be able to retro-fit an accelerometer to the v1.0 hardware. I was thinking about some daughter board holding the accelerometer and some passives and then connecting it to some pads/traces.- If possible, any docs on what to do, or schematics to look at?
- In either case, it might be a good idea for a future revision to break out every (unused) signal/pin to testpoints so patch boards can be made.
