What happened?

When the board is reset, either by hardware reset pin or CTRL-R in Fluidterm, the spindle runs for a second or so while the ESP32 is resetting. It seems to start before the ESP32 gives its reset diagnostic message. This doesn't happen on a power-on reset.

It is very difficult to control the state of I2SO pins during reset. Bart's controllers have some tricky hardware to try and keep them at 0 then, but it doesn't always work. I doubt that MKS DLC32 even tries. You might need to use a different pin for the spindle enable.
