Any chance we can have an option for the BLTouch high speed mode profile in the custom firmware builder?

BLTOUCH\_HS\_MODE is set automatically when the BLTouch is selected.

Come across this looking for the same info. Ender 3 pro with 4.2.7 board, BLTouch.  
When i download the latest firmware it has HS\_mode enabled and is really quick. I do the custom build with BLTouch and its alot slower. Is it possible to get the same hs mode as the nightly build profiles?  
Cheers

A high-speed profile option to enable in custom firmware builder would be great

You should be able to enable High Speed mode with the G-code `M401 S1`.

You can also disable high speed mode with `M401 S0`.

It’s no longer required to set it in firmware at build time.
