2 PT100 daughterboards for the bed heaters, Code?

axiom · 14 Jul 2022, 13:54

Hello,
I am currently building a relatively large 3D printer. My board is a Duet2 Wifi. Since I don't have any experience yet, I used the RRF Config Tool for the configuration. I can already address and move the axes, I can also warm up the 2 print heads, but they are displayed somewhat awkwardly in the terminal. The heating bed consists of 4 heating elements, each 400x400mm. So I have a total of 4250 watts. I have planned 2 PT100 daughterboards for this and hopefully I have connected them correctly according to the instructions (see photos) . I don't understand the description in the instructions, especially how to get the elements visible in the terminal. I am attaching the current code and some photos. The second question is how can I address the 2 extruders for the 2 print heads.
Can someone send me a code that I can just copy and paste?
best regards

@axiom
Da hat was mit den Fotos nicht geklappt.
Eventuell sind die von der Dateigröße her zu groß ?

---- Translated Text ------

Something went wrong with the photos.
Maybe the file size is too big?

@günter-jibben Danke für den Tip!....da passt ja grad mal ein kleines Foto rein!

So you have 2 PT100 daughterboards and 4 PT100 sensors?

Which sensor is connected to which heating element?

In the config tool you can select the PT100 channels from the sensor drop down in the I/O Mapping tab.

And here is a basic example config using 3 PT100 sensors one each for bed and 2 hot ends.
