This is the same as before. My config is set so that tool 1 & 2 use fans that I've defined as 2 & 3. With the config from my previous post, all the heatbreak fans run except for those two even though all the temperature readings are above the temperature point.

@phaedrux

I ran the code you suggested and those came back without any errors. The full results are attached.

I also added a G4 S4 to my code and rewired the fans so that they were on the same boards. The updated config.g that reflects these changes is also attached.
config.g

However, I'm still having trouble with getting my fans for tool 1 & 2 to operate.

I'm having trouble running six fans for six E3D-V6 extruders on thermo mode. Attached is my config.g.

config.g

When running this config, heatbreak fans 2 & 3 do not run. When I mess around with the H# that they're attached to, they will run. When I set all of the heat break fans to run on thermo-mode while looking at the same heater (e.g. H1), some run and some do not.

I've confirmed that each fan runs individually, and I can read the temperature and heat each extruder just fine. Any advice?

I am running a Duet 3 MB6HC with 3 expansion boards, DSF Version 3.3.0, RRF 3.3

Thanks!
