Duet 3 6HC - Short to ground issue.
-
I received my Duet 3 last week; I had time to install it until Monday; unfortunately, Driver 0 and Driver 1 are not working, motors vibrate, and in the Duet Web Control there is a message saying "Short-to-ground reported by drivers #(number of driver)". I tested the same motors/wires in drivers 2-5, and they work perfectly, my system has dual Z and X-axis, so I really need the 6 driver channels. The serial number is WD41385.

hello are you powering the card at 24volt?
-
@Erika-de-la-Cruz Please email info@duet3d.com if you have not already done so. Thanks.

@tony73 thanks, helpful to track the boards that are working well as well.

Hi there,
I have one of these matching boards, serial number WD41269 with those KAXS4 diodes.
Right now I'm using a 12V power supply and the board is working fine, no errors or anything using 5 of the 6 drivers.My question considering warranty as I do plan switching to 24V in the future.
Will I need to rush upgrading the printer to 24V so I don't miss the warranty time?
I bought the board from E3D a couple weeks back, so it's mostly so I can manage things and plan ahead.Thanks.

@Phaedrux Hi, thank you! I've already contacted filastruder, in fact, I posted here because they sent me a form to fill, which asked to do so.
-
@tony73 Hi, yes, I have a 24v system and was trying to upgrade from a Duet 2, I've contacted filastruder support, and I'll send the board back soon for a replacement. Thank you.
-
@Ralms please contact info@duet3d.com I don't want to rush the upgrade for you.

Hi all,
I'm a noob with the Duet hardware and just got my first duet card with the Duet 3 6HC which I received a couple of weeks ago but haven't get the time to install it yet.
Here's my card serial, D3MB6HCV1.01 / WD41551; are you able to let me know if the card is impacted by the issue and if so should I reach out to the reseller for a replacement?
Thanks
-
@aldiallo the only way to tell for sure is test the drivers on 24V power. You are covered by warranty so its worth testing it before returning it as only part of this batch is affected.

Thanks T3P3Tony, I'll make some time this weekend and will give it a try and advise

Hi also having the issue with short to ground, already emailed support and needed to post on the forum to start the replacement process with filastruder. Serial number WD41384 with KAXS4 diodes short to ground on all drivers with 24v
-
It has been a learning experience. I will be patient though. Is the problem fixed on boards being produced now?
Is there something I can do to fix the circuit or is it the PCB itself?
This board was purchased from PrintedSolid.com (good vendor BTW).
Board SN WD41585...
-
@maxspongebob thanks for your email. and to answer the specific question. it was an issue with a specific batch of diodes. Other boards are not affected.
-
Is this issue resolved?
Do you have any ETA on resume of sale?
I need to order some boards! -
@aleohl We are working with our resellers to exchange boards with the fault. depending on where you are your local reseller may already have replacements boards.

I am experiencing short to ground fault on all but driver output that I have tested. I purchased my board through Printed Solid and the Serial # is WD4159.

@wikipedia_Brown You will need to provide the SN of your board along with a copy of the results of the M122 command and send it to info@duet3d.com. They should confirm that it is to be replaced.
Once you have that confirmation from duet3d, send a message to support@printedsolid.com. Include the confirmation and then they will send you an RMA#.
I got a message from Dustin at Printed Solid today saying that they do not yet have replacement boards.
Hopefully soon.

@T3P3Tony, Can you tell us what vendors have the new corrected boards already?
