Is it possible to adjust left and right fan speed individually?

[gareee 37]

I see a fan speed adjustment under Tune, but I don't see a left/right fan option.

The reason I ask, is the right side print issue on things like the ultimaker robot's right ear. Its apparently caused by the extra space for the second extruder option, and the fan on the right being further away.

A simple solution to me seems to be to across the board increase that right fan speed by a certain percent so it cools that same amount as the left fan. If we have individual fan speed settings, that might be an easy option.

Or is that locked out in firmware or hardware design?

The 12v fans are in series across a 24v power line, thus not possible to adjust individually. You could, however, buy a couple of aftermarket fans running at different speeds.

You could connect the second fan to the led pwm and use the search/replace on the gcode to change the speed. But I did this on um2.1 board.

Ofc on um2 you can't just plug one fan since they are 12v.

Its funny.. I'd think this would have been one of the first improvements on the + models.
