Anything else?

This issue has already been raised here, but it is closed without any comments. The problem is that in the settings Orca uses the code "M106 P3 S123", however, in the latest firmware of the printer V1.3.3.29 (+ root + Fluidd) the numbering is used as follows:

P0 = Print head fan P1 = Housing fan (exhaust fan) P2 = Side fan

Of course, instead of the correct numbering P1, the number P3 is inserted into the gcod to turn on the exhaust fan. Therefore, the fan does not start. I do not know if it is possible to change the fan numbering in the printer itself, so I am writing here. Perhaps in orca you can make parameters for numbering fans.
