### Basic Information: Struggling to get uuid
Printer Model: custom
MCU / Printerboard:
`klippy.lo [klippy (2).log|attachment](upload://rOUasGqk23lqENsziR850u3laGN.log) (1.6 MB) `
FIrst time using the SHT32 board and am struggling to get the Raspery pi 3 to see the tool head board. The can board seems to be working fine but when I look to pull the uuid I cant find it. Ive gone through all of the documents and a friend and I are struggling.
Any help would be great.
Edit:
Ive managed to get a can network going but still cant see the uuid for the SHT36.

It would greatly help if you specified just how the board is connected.

Can you go through the process (listing all the commands that you went through)?
Just as a quick one, how did you confirm the FLY SHT was in DFU mode?

After going through this [MELLOW FLY SHT 36 v2 | klipper\_canbus](https://maz0r.github.io/klipper_canbus/toolhead/sht36v2.html) I have set up the can network and the SHT board shows up with a UUID.
Now when building the klipper config I get the error code that there is an unknown pin sht.

If I look at line 234 of your `printer.cfg`, you have:
```auto
mcu: sht
```
Shouldn’t it be:
```auto
mcu: sht36
```
To match the device identified on line 216?
