Please help.

because the octopus board doesn't have a 4 pin header for fans
you uncommented line 153 when you shouldn't have
you also have a bunch of other stuff in there you don't need
okay sorry I am still a total noob. for some reason the 4028 fan goes to 100% on startup even though I have the pin settings the same from my configuration before I updated to the latest frimware. What other stuff should I get rid of?
sounds like this problem? https://os.ratrig.com/docs/guides/4028#my-fan-runs-at-100-until-klipper-boots
What other stuff should I get rid of?you have a bunch of stuff that is just repeating the defaults (line 322 and down)
I changed the sample retract distance on the bl touch from 10 to 15 and I added z tilt to the startup sequence. Other than that I'm just leaving default values in there. Can this cause issues? I followed the instructions from that page the first time I set up the printer. I copied my code for [fan] from my original .cfg to the override section in this new .cfg exactly the way I had it before but it is no longer operating as expected...100% fan on startup even though I have the ground connected to negative on the heater 1 port.
added z tilt to the startup sequencethat is already in the START_PRINT macro
ah
face palm
it seems that the settings for the 4028 are reversed...I think you made a post about this somewhere. at 85% fan setting the 4028 just turns on and goes up in rpm down to 1%
fixed it...redundant stuff below was messing that up
okay I deleted all of the extra stuff except for my modified bltouch setting and the lines for handling the 4028 setup
