I asked this elsewhere, did not see anything appear for what I thought was a long time, and reposted it here - then it appeared there. The thing I observed is not actually causing me a problem. I thought it might but it was not - I sorted the problem without addressing this. So, I am not worried about it, if this is happening, I don't care.

No, I guess I was not clear. The fan comes on when switched on. But after a print (not immediately after a reset), between prints when the cooling fan is normally off, I preheat the extruder, then extrude some filament from the front panel. For the short time that the extruder motor is running, the cooling fan comes on and then immediately goes off.
While I could write such a sketch with only

Thanks for replying. I used the online program to build my configuration.h. This is the relevant part from the json, I think. Sigh. I started in this business when state of the art was punch cards and terminals were usually reworked typewriters. Or teletypes. This jus seems excessive. As I get this, the fan pin is set to "ORIG_FAN_PIN" which matches what I see in the regular c preprocessor

OK, I have a MKS 1.5 board, which is supposed to be a combination Arduino/Ramps board on a delta printer. The board has a non-controllable, always on 24 volt outlet which is used by the cold end fan and a separate layer cooling fan which is attached to the fan terminals. This is a bowden setup, so there is no co-location of the fan wires and the extruder stepper wires once they leave the board
