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.

peter247

@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

@Gost101

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:

@peter247 said in BL Touch:

M280 P3 S160

The only way to clear the blinking red light is to manually unplug the red wire: alt text

Gost101

This isn't a actually picture of my board just one I found online.

Gost101

@peter247 I tired the M280 P7 S160 through both the gcode console and in home all and it dindn't work

peter247

@Gost101

Does the up down up down up down work ?

Gost101

Nope. lol. I manually reset the bl touch but am curious if there is a reset g code for this problem.

peter247

@Gost101

this my reset code for the bltouch M280 P0 S160

does this work ?

@peter247 It doesn't so far, I get error:

this Just checks the probe not homing .
You need to home X and Y before you can home Z

Gost101

@peter247 Im trying reset the bl touch then home X&Y axis to zero. Then move Z axis up 10 Y axis 15 and X axis 15 then actuate the probe 3 times, then home down z.

@Gost101 to me, it sounds like your probe is not correctly wired. To get it to self test, all you need is 5V on the red wire, and GND on the black or brown wire (sometimes blue). Check continuity of these connections. It sounds like you have 5V on yellow.
