v4.2.7 BLTouch v3.1 + Filament sensor and fire hazard from BLTouch and v4.2.7 board?
Reading the post below, getting the BLTouch seems to be easy(albeit pin27 adaptor board is still needed), however, how does one install a filament sensor?
And how can one prevent from burning up the PCBA while installing BLTouch?
Some users have noticed that for installing a BLTouch, the ports used vary based on what firmware you’re using. Plugging the Z probe wires into the wrong ports (such as the Z-axis endstop rather than the specified Z probe port) has reportedly led to smoking on the board, despite the fuse. While the fuse is a nice added security feature, it clearly doesn’t prevent all issues, so this is something to be wary of as you upgrade your printer.
