BLtouch on 24V GT2560

I'm running a GT2560 on 24V with the jumper in place and am in the process of adding a BLtouch sensor (on the Zmin and max pins as per the Geeetech instructions for the older GT2560)

Now I'm wondering, will I kill the BLtouch as I'm running 24 Volts ??

Thanks, working indeed.

Only had to add the SERVO0_PIN 32 in pins_gt2560_A to make it work, this one is normally assigned to the endswitch and is not assigned to the BLTouch (it is corrected in the A+ pins but since I use the older A revision where I soldered a 3-pin header to the z-endswitch.....)

It worked for 2 hours or so.. then the BLtouch lost the red led... After checking, the +5V pin on the GT2560 (the one extended from the z-axis endswitch as per the Geeetech recommendations) has no more 5V... the ones next to it do strange enough.. Any hints on this ? Crack in the PCB ?? Solder a wire now to the neigbouring +5V and hope it will stay alive....
