Duet 3 MB 6 HC - Temperature control does not work. During the reading the temperature sensor, the temperature rises very fast up to 400C . Then the control unit detects the error. I could send you the unit and I would like to claim for replacement, invoice no. INV 0503. Thanks.

We have Duet 2 Main board (419.1712) and we use it for more than 1 year.
A month ago, Duet 2 began to mismanage the print head temperature. This is because the nozzle is slightly melted and the material jams in the feeder. During the test protocol for the temperature M303 h1 s240, a strange warning message began to appear at the end of the test, which I am sending in the attachment. I replaced the PT 100 temperature sensor, I replaced the PT100 daughter board, I replaced the heating cartridges. The warning message always appears during the temperature test m303 h1 s240. Could you please help us with this problem?

@Phaedrux We bought the Duet3D directly from you (invoice no. 0043). Is it possible to send a new piece? Could you please contact me via email to resolve? Thank you.

I can also send these photos in high resolution to your mail.
V light indicator doesn't work.

@Phaedrux Yes! 

and ventilator and endstops.

Just drivers...

Hello,
We have problems with our DUER3 control unit.
We connected the control unit duet 3 according to your setup on duet3d.dozuki. When the source was connected, the control unit started smoked a bit. After connecting the other connectors, we found out that the 5 and 3.3 V power supply does not work. The printer only prints if the usb connector is connected to the computer. We try to connect another DUET3 control unit in the same way and it works correctly. We wanted to ask if it would be possible to repair or replace the control unit, or at least find out what we did wrong during the connection. We could send the wrong unit to your adress... Thank you.
