BL touch help

Hello,

I mount a bltouch probe on the duet wifi. The bltouch is version 2.1.
Do I have to cut the copper line on the bltouch logic board to convert it to 3.3 logic or I can leave it as is ?

I also cannot understand what is the difference between the 2 following modes and if I need to activate one of these 2 (or is done automatically)….
Probing with Push-pin Down
Probing with Touch Switch Mode ← only Smart V2.1 and later

Thanks a lot
George

If it's a version 1.04 Duet WiFi then you don't need to cut that trace. If it's 1.03 or earlier, cut it.
