@remixbot Ok, that seems to be wrong.

You might want to adjust position of homing point changing line with:

G1 X5 Y5 F6000 ;go to first probe point

BTW - did You use configtool, and set bltouch there? it generates proper config files.

A Former User

yes i did use config tool

A Former User

but can't seem to wrap mye head arround the pin assignment i config tool.
Pin Assignment
Input Pin
zprobe.in
Modulation Pin
zprobe.mod
PWM Control Channel (BLTouch only)

@remixbot
Pin assgnemnt:

Z endstop

A Former User

still crashing into the bed

BoA

Is BL Touch deployed, but bed not detected? Or not deployed at all?
Describe what and where You connected (from BLtouch).

A Former User

bed is not detected

A Former User

the bltouch is connencted to gnd and signal on probe in. and pin 1, 2 and 8 on the expansion

@remixbot

post a picture of your wiring

To use the probe you need to use G30 as shown by BoA in his example homing files.

If your wiring is correct and the config uses those correct pins and it still doesn't trigger but the servo commands work, then it's likely a bad connection on the white wire, which is the trigger signal.
