Enable pins on Stepper driver, are they required?

Been there, done that, lost a fingernail (but it has regrown, albeit lumpy). This is why I asked about braking resistors, as my little trip to the world of pain was taken while the cutter was on run-down.

Rob you should see this then https://www.youtube.com/watch?v=eiYoBbEZwlk they are made commercially they wreck the saw though I think there are types that clamp the blade with an explosive charge like a air bag.

My lathe has an electro-magnetic brake. I was worried that it might not work with the VFD I use to generate three-phase power but it actually works very well and brings a heavy chuck to a halt from 2K rpm in a surprisingly short time. Don't think I'll bother with trying to fit one to my 24K rpm spindle, though...
