    I need some advice to debug a part cooling fan issue. Tools 0, 1 and 2 work fine but Tool3 has an issues. I can not get M1064 P8 S255 to enable the fan. All other fans 2-6 work as expected.
    I have tried multiple fans
    I have checked with a multi-meter and confirmed 24v is not getting enabled.

    Any tips on where to start debugging this if it is a hardware issue?

    What firmware version are you running? Older firmware versions don't support fan 8.

    That's very recent, so it supports fan 8. Try sending [EDIT] M106 P8 to check that the firmware recognises the fan 8 port.

    Yes, it should report the current speed setting and whether thermostatic mode is set. In general, if you send any command to RRF with no parameters or just the item number parameter, it will report the current settings.

    Thanks. I tried M108 P8 in the web console and get no response codes.
    I enabled P2 and tried M108 P2 and also get no response
    See image:
    M108.png

    Since all other fans are working. I was thinking of just using P0 as its unused. any downside to using P0?
    I'm concerned that I'm not getting the expected response codes from M108 Px. Could that point to some other issue?

    On a hunch... I tried M106 P2 not M108 as wiki calls M108 as "cancel heating"
    M106 P2 and M106 P8 both return the expected values and importantly, yes P8 is recognized.
    See image:
    m106.png

    So any points I can check on the board to see if that Pin is damaged? It's strange that all but this one fan works.
    Also, per my earlier post, I could just swap to P0 for this fan. Any downside?
    is there another 24v output I could reuse on the Duex5?

    Yes you could swap to P0. But I suggest you ask E3D to replace your DueX5.
