BL-Touch - Voltage?
-
hey,
the configuration tool tells me that I have to switch from 5v to 3.3v concerning the BL-Touch. What do I have to switch and how to do it?
And do I have to wire only to 4 pins on deut3 6hc?
thanks a lot -

- voltage depends on the version of bltouch, newest ones are working either way, older ones you need to cut one trace and oldest ones do not work on 3V
- wires - bltouch comes with 2xgnd so you need to connect only one, the other one is not required. So min is Vcc, Vss, Servo, Signal.

thank you!! -
Duet 3 is 5V tolerant, so even if using an old version of BLTouch it does not need to be set to 3.3V.
