Fan problem

Printer has two fans, fan0 is hot end fan and has temperature control set and comes on at 45C. Fan1 is print cooling fan. Printing ABS I only want hot end fan on. Untick cooling and it sends M107 which turns off fan0. Is there any way in cura to define fan numbers? Tried on both Cura 3.3.1 and 3.4 beta.

    Maybe a bug, but post processing plugin does absolutely nothing in 3.3.1 or 3.4Beta. Possibly because my install is 64bit, if the plugings are not compatible they wont work. Several other plugins don't work either.

    I submitted PRs to allow the cooling fan number to be specified on a per-printer basis.

    Don't get too excited, these are unlikely to be incorporated for months (assuming they get accepted, that is).
