@T3P3Tony I doublechecked, there are indeed just 32 connectors in the package. Weird, I bought the Duet from your official reseller Dold Mechatronik here in Germany and it did not seem to have been tampered with.

Anyway, thanks a lot for your offer! But while I do highly appreciate it, it does not really make sense to force you to ship a couple of these connectors to Germany. I will buy them here instead, then I will get them faster - and in exchange I will prefer to nag you quite probably with some more questions here when the printer runs with its new heart - Phaedrux knows what I am up to and the current state 😉
(In case anyone else has the same problem, Reichelt Elektronik sells them for 10 Cent a piece.)

By the way, by searching for the part no. you mentioned I actually stumbled upon the site in your documentation where the separate parts of the crimp connectors are listed (albeit with a nonexistant JST part no. at least for the VH connector I need, see https://www.jst-mfg.com/product/pdf/eng/eVH.pdf for the correct one): https://docs.duet3d.com/User_manual/Troubleshooting/Parts

May I suggest you add a link to that page to the appropriate section of https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6HC_Hardware_Overview ?

@droftarts Thanks very much!

@tylersuard it’s really only intended for high-end/large printers, is a premium product, not mainstream.

Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.

@Makergal3D said in What I need to order:

I supposed they are the same in DUET.

The daughter boards are a bit different than the E3D amplifier boards.

Note to repairer for this board: check the BAT40V diodes and mosfet gate series resistors. If those are OK then replace the output mosfets for that phase.

@T3P3Tony thanks allot.
i'll contact local distributor tomorrow to check if they don't have the never ver. for sure .if not i'll contact you.

@dc42 No problem. It's my first fail in about 50 boards, so I'm not complaining. I will follow your instructions. Thanks

@dc42 Thanks, I'll send an email over to them!

@shiga I'd imagine people will only tell you where to buy a genuine Duet product and without knowing where you are located that's not going to be possible.

The duet website lists the official resellers. https://www.duet3d.com/page/genuine-resellers

What part of the board is getting hot?
What do you have connected to it?
Photos?

Have you gone through this guide?

Or perhaps this one?

When and where did you purchase your Duet?

Unfortunately, I think the best we can do here is to offer a refurbished replacement at reduced cost on exchange. Please contact roland@duet3d.com to enquire about availability and include a link to this thread.

@phaedrux

So now I know what to fix in the config when a new duet arrives 😃
Thanks.

Email message is sent.

@phaedrux OK, thanks for that, I though it would be something silly.

@stephen6309 I can't do it now I am gonna try this tomorrow.

@c310 the change from previous versions to v2.0 was to increase the strength of the magnet which has allowed us to have more confidence in users printing there own housings. We may bring out a assembled version with a housing if we can get the housings manufactured at a reasonable cost. but we are not planning on changing anything functional with the design.

I think the confusion is the PCBs are version 1.7b, its just the magnetic assembly that is now v2.

Our European resellers should have stock of this as a kit - if your favourite reseller does not then please encourage them to stock up 😄 (I just checked a few (1,2,3) and they did have stock).

@j2s said in PCBs available - Duet3 6HC v1.01 / Exp. 3HC v1.0:

Believe or not, people in a lab I work can populate similar things without reflow or paste mask. Yes one board takes one day

I've done that in the past myself, but we had a vapor phase oven and a manual pick and place machine. But I can't imagine populating a bord without having solder paste applied (with a paste mask)
Trying to place a 0401 capacitor with plyers ends up in crawling under the desk and trying to find the lost components 😉

Please contact oozenest and initiate a warranty exchange. Include a link to this thread as authorization.

@kroybal if you are happy printing the housing then you can email sales@duet3d.com to get the components

@magdi if this is shipping damage then please go back to e3d to sort as its not covered by our warranty policy.

Sorry for the run around.

if you monitor the duet 3 5 mini thread you will see that e3d got two batches.
when e3d will get the next one i do not know

That's brilliant, thanks so much!

@vistalert
First off, a quick description of what a tool is, because that's what you'll have - 4 tools. Essentially a tool consists of an extruder, a heater and a temperature sensor. There is also usually a heat sink cooling fan but this is associated with a heater/temperature sensor so it's not strictly part of a tool. Optionally there will be a part cooling fan and you'll likely have one per tool.

So you need to connect 4 heaters, 4 temperature sensors, 4 hot end cooling fans, 4 extruder motors and optionally up to 4 part cooling fans (you could maybe use one fan per pair of hot ends (tools)). There are also things like end stop switches and/or Z probes to think about.

You've got a couple of options - either the expansion board or what might be a better option would be to use tool boards for each extruder. It all depends on where you plan to mount the extruders. If you use a single expansion board, then you'll need to connect one tool (heater, temp sensor, heat sink fan and extruder motor) to the main board and the other 3 tools to the expansion board. So all the wiring will go to either of two central points (the main board or the expansion board).

What might work better would be to use tool boards instead of the expansion board. That would allow you to mount each tool board close to each extruder for example. Of course you'll still need to run wires from each tool board to each heater/temp sensor/fan etc. Alternatively, you could mount tool boards on the carriage. This would make wiring the heaters, sensor,fans etc a lot easier and neater but of course, you then have longer runs of cable from the tool boards to the extruders motors. Having tool boards on the carriage might also simplify connecting a Z probe but check the list of firmware limitation here https://duet3d.dozuki.com/Wiki/Duet_3_firmware_configuration_limitations

Actually, there is a third option which is to use Duet 2. So you'd need the Duet Ethernet or Wi-Fi plus the Duex5. But in this case, all the wiring has to go back to a central point because the Duex5 has to be very close to the main board.

Edit. I've only recently started to use YouTube more. There is a lot more stuff in my blog if you haven't already seen that (link n my signature).
