Don't worry I just got the OK to get another. To be honest I have really been putting these boards through their paces with different things and have already had one replaced, and a lot of the time the duet is the only thing that has worked so happy to buy another. cheers!

oh dear! thanks for the info. does that mean I have invalidated the warranty?

thanks for quick reply

I was yes, but have tried it without, and some cards as well which work with the other boards. The board has only been turned on and done basic moves and switch checks a while ago, now everything else has been built around it I started setup proper and same issue. With the other board it occurred during operation and I think this might have always been like this but could be wrong.
I can double check everything but am away from the lab atm

Hi,

unfortunately another board has developed a similar fault not reading any sd cards, the same as in https://forum.duet3d.com/topic/10603/sd-card-slot-failed-on-duet-wifi/2

is it ok to get a confirmation to return

thanks a lot

thanks for your help

ok thanks, would you say it needs returning then?

no card shows in the platform section using M122 diagnostics

Do you mean that it reports "SD card 0 not detected" ? If so, that probably means that the Card Detect pin on the SD card socket isn't soldered down well enough. Unless you are very confident of your fine-pitch component soldering skills, please ask your supplier to replace the Duet.

Actually, apologies it does say sd card 0 detected

Hi, I am not sure if one of the new duet boards I have has a problem - it has stopped reading the sd card, when I try to go to the web interface it now says

Your Duet rejected the HTTP request: page not found
Check that the SD card is mounted and has the correct files in its /www folder

I have copied over these www folder files to no effect

using YAT I get the following responses

M21: Cannot initialise SD card 0: Card is unusable<LF>ok<LF>
M39: No SD card mounted in slot 0<LF>ok<LF>

no card shows in the platform section using M122 diagnostics

I have tried a few cards that all work in my other Duet but no joy.

Is there anything else I can try?

thanks

Rich

Thanks, I found the M570 command which has helped a lot!

Hi, I am developing a few custom 3D printers as part of my research, one of them being asphalt (first paper here - https://www.sciencedirect.com/science/article/pii/S026412751830724X)

I have been through so many boards over the years and it looks like the duet is the best one but using the extruders I have developed throws up so many heater errors that require a full reset, even with calibration. Also part of my work will need to modulate the temperature as it is printing which the Duet also doesnt seem to like.

How can I disable the heater protections on the board? is it possible?

many thanks

Rich
