      Ah yes, of course. That's was a common problem with the BLTouch which needs a heater pin unbound as well.

      It seems I have not read the docs as good as I thought. The L Parameter of the M106-Command fixes my problem. This is the minimum Power for this fan.

      M950 F1 C"duex.fan8+^duex.pb6" M106 P1 C"HeatSinkFan" S0 H1 T45 L255

      I found this out when investigating the fan status by running M106 P1. It only turned with 50% power.

      @droftarts I was right - it was simple. Thanks Ian both fans now working as expected.

      @martin1454 said in Gcode macro - Get parameter (fan rpm):

      Is there any way to get what the current "fan speed" is for an output...

      Yes, send M106 with just a P parameter to specify the fan,

      ...and use that value to subtract 25 and write to m106?

      Not yet.

      @pro3d said in Will 12v fan on 24Vin blow up the board?:

      @dc42
      Thanks for the response! Not many radial 4020 blowers on 24v

      But can connecting wrong fan to one port destroy all of the FAN outs?

      Shorting one fan output can damage a trace on older Duets, or blow the 1A fuse on revision 1.03 Duets. But in that case, the fans won't run at all.

      Followup question
      I also connected the bl touch before making it 3.3v ready --- Are more components now dead?

      Unlikely. We can't guarantee it, but the endstop and Z probe inputs will generally tolerate a lot of over-voltage without damage.

      The heatsink fans supplied by E3D do not work with PWM, so you will have to be content with turning them on and off.
