The newest duet 3 mini wifi. I think .02 version?

about 25C. Bed was cooling. Sorry - i claimed that bed was accurate.

Anyone know why my temp sensors would read such a low number? In ambiet room - bed temp is true. Pt1000 hotend temp claims 7.5 degrees. These are slice engineering PT1000 sensors. Firmware:

M308 S1 P"temp1" Y"PT1000" A"RTemp" ;Pt1000 located in right side of hot block
M308 S2 P"temp2" Y"PT1000" A"LTemp" ;Pt1000 located in left side of hot block
M950 H1 C"out1+out2" T1 ;2 Heaters wired to separate connectors but treated as a single logical heater
M570 H1 S360 ;Hot end may be a little slow to heat up so allow it 180 seconds
M143 H1 S310 P1 T1 A0 ;Monitor heaters with sensor 1
M143 H1 S310 P1 T2 A0 ;Monitor heaters with sensor 2

Doesnt seem to matter if i switch them... I've tried everything under my small umbrella of knowledge. Vref, Voltage to sensors. I see talk of resistance stuff but i am not sure how to do that?

@Phaedrux all purchase feb 2022, wasn’t installed untill November 2022.

I bought a single replacement with new chip this year but that one is working - only one of 4 that is.

@Phaedrux

They were purchased from fillastruder.

202106-0131 : both hotend temp sensor inputs do not work.

202106-0138 : cannot connect to Wi-Fi. Cannot connect to pc with usb cable. Most things do not work

The other was is still mount to the machine: I get the error listed above. Seems to be as card socket doesn’t work.

@dc42 I get this error when trying to remount the SD card - it does this for 2 different cards.

WiFi module is connected to access point *********, IP address 192.168.68.107
Error: M21: Cannot initialise SD card 0: Card is unusable
ok
M21;
Error: M21: Cannot initialise SD card 0: Card is unusable
ok

Also the usb connection seems to interrupt when I power on the machine - as opposed to just being powered through the usb.

@dc42 I don't really have time to do this type of repair. I have 2 boards that are not in use. Is there anythign duet can do as far as warranty replacments?

I have 4 boards total - all duet 5 mini - 2 of them are described in this thread. A third just started doing this:

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 reformatted a new card and tried the help section in https://forum.duet3d.com/topic/6798/your-duet-rejected-the-http-request-page-not-found.

with no luck.

So now I just have the 1 board working on 1 printer..

Does anyone mind looking over my config file? I keep getting this error when i run it but everything seems to be working fine:

@dc42 I totally rewired everything. I did as you suggested for new wiring (ordered a new board).

I tested the temp inputs, i get no reading on 1 or 2, and 0 works. If i were to replace said resistor.... where would i find information on this?

Anything about a warranty claim?

@Phaedrux Thankyou
