Two print cooling fans with separate connection headers
-
Some printers run two fans as print cooling fans. One from the left side and another from the right side.
Let's say I would like to connect each fan to a separate header, but control them together at the same time (always). I know I can just group them into a single header, but for this experiment - that's not what I want.
I've been digging around, but can't find an answer.
Is it at all possible to configure two separate fans to work as a single P0 one? Let's assume my slicer sends only a simple M106 command, so we can't rely on multiple M106 P# commands. Has to be M106 S255 for example.

@pkos Yes. The way to do it is to map both fans to the tool using M563 https://duet3d.dozuki.com/Wiki/M563. So if your two fans were defined as fans 1 and 2, and you had a single tool using a single extruder, and a single heater, then your M563 would look like this M563 P0 D0 H1 F1:2. Where P is the tool number (usually 0 if you only have one tool ), D is the extruder drive to use, H is the heater, and F is/are the fans.
