Problem assigning more than one fan to a tool (Solved)

[A Former User]

Afternoon Gents

With regards M563 and mapping more than one fan to an assigned tool.

I was attempting to undertake this task today and for the life on me I couldnt fathom out why I couldnt get M563 to turn on BOTH fans.

I was following the instructions from the following link:

https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter?revisionid=HEAD

The section about mapping fans to tools had no mention of mapping more than one fan to a particular tool. So I tried a couple of iterations of the M563 command.

M563 P0 D0 H1 F0 F2 (that didnt work)

Then I tried

M563 P0 D0 H1 F0,F2 (that didnt work either)

Then I tried

M563 P0 D0 H1 F0
M563 P0 D0 H1 F2

And that didnt work either. Hmmmmm time to research further.

This led me to check the G-Code page of the wiki.

https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD

Particularly the M563 section, which hidden in the middle of that section has the following command:

M563 P2 D0:1 H1:2 X0:3 F0:2 ; create a tool using extruder drives 0 and 1, heaters 1 and 2, with X movement mapped to both X and U axes and fan 0 mapped to fans 0 and 2

Now this is perfect it explains how to carry out what I wanted to do perfectly well but it is not actually highlighted as a seperate feature, so unless you really go digging its not that simple to find.

So (and I hope this is ok) I have updated both pages on the wiki to seperately mention how to map 2 fans to one tool to make it easier to find.
