@aidar thank you so much .. bad connection .. solved & back in business

@aidar changed P to 25 .. no change
no response to M401 / M402, although on the web interface it gives a check mark as sent

@JoergS5 yes sir, deployprobe.g & retractprobe.g

@aidar did reboot .. same issue
changed : M558 P9 H5 F120 R0.2 T6000 A5 B1 ; set Z probe type to bltouch and the dive height + speeds
to : M558 P3 H5 F120 R0.2 T6000 A5 B1 ; set Z probe type to bltouch and the dive height + speeds
got a reading on the zprobe (18) but still slamed the bed, wnt back to :
M558 P9 H5 F120 R0.2 T6000 A5 B1 ; set Z probe type to bltouch and the dive height + speeds

@aidar same .. no change .. still slams the bed

@aidar thank you
will try now

hello,
thank you in advanced.
due the test runs im facing a problem with BLTouch z-probe on my Cartesian CR10S5.
it worked for the first time only. then no response although when i pull the trigger and push back it lits as it should.
please advice ..

@droftarts
yes, this is my initial setup,Im getting tips from here and there for each part due to the lack of a step by step guide for my machine (CR10 S5) which I intend to upgrade with a Duet 2 wifi.
here is my config file.
config.json
config.g

@dc42
will do, thank you for your swift reply.
