Thermostatically controlled fan, sensor on different board

p8blr

I have a BMG-X2 that I setup with two toolboards and I'm only using one heatsink cooling fan connected to one toolboard. The fan doesn't function unless I have it controlled by a sensor on the same toolboard.

M950 F0 C"22.out2" Q500
M106 P0 S255 T45 H1:2 C"Heatsink Fan"

According to the release notes though, it should work:

"[Duet 3 with expansion/tool boards] Expansion boards now track the temperatures of all sensors in the system. This means that a thermostatic fan connected to an expansion board can now be controlled by sensor(s) on different expansion boards(s)."

Can you post your full config.g and the results of sending M98 P"config.g" and M122 and M122 B# where # is the can address of your expansion boards?

@p8blr this is a known bug, fixed in the imminent 3.4.2rc3 release.

@dc42 Oh good to know! I'll give that version a try and see if it fixes the issue.

p8blr

@p8blr The new firmware fixed the issue! However, now I'm getting weird PID autotune errors, so I may make a new thread for that topic. Thank you for your help!
