"Connection interrupted, DCS has been stopped"

[nico.rast]

Hi guys,
yesterday after i resolve the problem with bltouch i did my first print.

But i didnt realize nothing xD.

I've some problems actually:

1. M140 i can't resolve
2. DCS has been stopped ( it appears during first layer then it stop)
3. I read Z0 but actually it's 5mm higher than 0 point.
4. Macro in simplify3d :

G90 ; absolute position
G1 X200 Y400 ; move probe to the center of the bed
G30 S-1 ; use the probe to find Z0
G1 X0 Y0 Z0 ; return to parked position

Someone can do me an online assistance? Like in discord?

Thanks
