Thanks, I confirm this as a bug. Will be fixed in next RC.

OK, Thanks. I can live with a bit of fan noise for now

Now running RC10. This issue still present.

gcode definition

; MCU
M308 S2 Y"mcu-temp" A"CPU"
M950 F2 C"!out4" A"MCU" Q25000 L.02  
M106 P2 T40:54 H2      ; set Duet cooling fan

Fan comes on @ 100% at just over 40 and doesn't go back off until 39, no ramp whatsoever

@Garfield I think I mentioned the issue was present in RC9 & 10. I singled out RC9 as that was when it first appeared

Must slow down and read - only saw the RC9 bit - tagged on because I saw your post and had issue, @DC42 indicated it was known and fixed in the next RC - but wasn't sure if he meant RC10 - I need to take a break from the printer this week I think .....

Bug fixes, and restore correct heigt after a tool change

Thermostatically-controlled fans were no longer forced to run at >=50%
PWM when on
Proportional control of thermostatic fans no longer worked
When restoring position after a pause or after skipping a build object,
the inverse bed compensation applied when recomputing the user position
did not take account of the tool offset
After a tool change, if on a FDM printer then we now move the new tool
to the correct Z height before resuming the print

I meant RC11. You can find preview RRF binaries (not fully tested) at https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0.

Not your fault here Dave - all mine .. speed read and responded too quickly ... just figuring that my backup process's are somewhat lacking after the RC10 crashes and re-applying updated configuration which is how I spotted this.

I'll try to do better.

@dc42 I can confirm that the internal build / preview binary no longer spins my case fan at 100%

Thanks for confirming this is fixed.

Just upgraded to 3.01RC11 and the bug is fixed.
Many Thanks
