Remove that line in config-override.g

Well, 2 prints later and it started doing it again.
After a closer look at the BLTouch I noticed that the plastic pin was slightly bend causing it to get stuck on the rim of the housing.
I removed the pin and carefully bend it back.

Seems to be working fine now.

Thought I would post this in case someone else experiences the same issue in the future

Try using the guide from Duet itself:

That's how I have it wired up.

Just make sure you connect the wires correctly. (And ofcourse do this when the machine is powered off)

Used a Sandisk 16GB card and that seems to have solved the issue.
I guess the unnamed/unbranded 4GB card went bad

@eldrad

Okay.
Now change the following in your config.g file:

M307 H7 A-1 C-1 D-1 ; Disable heater on PWM channel for BLTouch

H7 to H3

And delete the following line in config-override.g:

M307 H3 A340.0 C140.0 D5.5 S1.00 V0.0 B0

If you clicked Home Z then it calls the homez.g file. And as you can see in that file in doesn't move the Y axis in there.
So if you would click on Home All, it will perform a home all on all axis and this move the bed under the probe.

Glad it's working now!
And good luck on setting it up further

Just noticed you have the following command twice in your config.g

M307 H7 A-1 C-1 D-1 ; dissable heater 7 for bltouch

Make sure you delete the following lines in there since you have it already set in the Z-Probe BLTouch section:

; Custom settings are not configured
M307 H7 A-1 C-1 D-1 ; dissable heater 7 for bltouch
