@Gost101

Are you getting power and self test when you first give it power ?

Gost101

The pin does not drop or retract the bl touch is still blinking red while status code:

G28 Z
 
Error: Z probe already triggered at start of probing move
Error: Homing failed

@peter247 Power and self test?

@Gost101 said in BL Touch:

still blinking red

@peter247

Self test is when you first switch on the machine / give it power , the pin will deploy than retract and go solid red.

Gost101

@peter247 It hasn't done that yet so far even after multiple reboots.

@Gost101

if it doesn't do that it is a bltouch fault and not a configuration fault.
pull the pin and see if it is bent

Gost101

I legit unplugged the bl touch wires and plugged them back in. It did the move thing and actually homed z. lol

@Gost101

if you get the red flash the deploy and retract doesn't work until you reset it.
reset it by power recycle OR S160 , eg M280 P3 S160

Gost101

Granted it didnt stop and kept going but progress

Gost101

The Z axis wont stop moving down even after the plunger is pushed in.

@Gost101

can you deploy and retract the probe ?

Gost101

@peter247 I can deploy and retract the probe

Veti

the wires that come with the bltouch are notoriously bad.

Gost101

@Veti Also not long enough to reach my board. lol

Look like you are using G30 to lower the head on homing .
Can't see a fault on your config.g , but i'm on version 3.1.1 which is different.

@peter247 Now the printer wont home Z. lol here is the code for home all. I cannot pin up and down:
