Thermostatic fan on tools 1-3 not working

St Taw

I am upgrading my machine from RepRap V2 to V3.

Most functions are operational. However on tools 1 to 3 the thermosatic fan on the hot end is not turning on when the hot end is heated. Tool 0 hot end fan works correctly.

I test by setting the hot end to 50C and expect the hot end fan to turn on. IT works on tool 0 but not 1-3.

I have created test macros to prove the fans are all configure correctly and can be turned on/off by the appropriate commands.

The temperature of the hot ends appears correct of PanelDue and DWS.

Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.5 (2022-11-30)
Duet WiFi Server Version: 1.23

Extract from config.g for Tool 1

M106 P3 S1 H1 T45 ; Set fan 3, H1=Thermostatic controlled, T45=max temp 45C, Tool 1 Extruder Heastsink

Any suggestions if this is a configuration issue or something else.

Should I supply full config.g in this topic?

Thanks.

@St-Taw I think you have the wrong sensor in the M106 command. You have H1 when it should (probably) be H2.
bear in mind the H number is the sensor number (from M308) not the hotend number

@jay_s_uk You are correct. I have now fixed it. Much appreciated and thanks for your reply.
