BLtouch issue

Phaedrux

"Error: Failed to enable endstops".

Post your homing files please.

Use M115 to verify that you are actually running 3.1.1
Then send M98 P"config.g" and report any errors.

M584 X0.0 Y0.1 Z0.2 E0.4:05

not related to bltouch, but you have a missing dot here
E0.4:05 => E0.4:0.5
(probably makes no difference, just visually disturbed me)

@vishiano Only error from M98 is

M98 P"config.g"
Warning: M307: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 356C

I have a separate issue with my heated bed which I believe to be unrelated to the BLtouch issue

@JoergS5 It bothered me enough that I fixed it

Your homing files are set to use endstops for X Y and Z, but you have only defined endstops for X and Y.

If you are using a probe for the Z axis, you need to change your homing files to use a G1 X Y move to position the probe, and then a G30 to probe the bed in place of this part:

G1 H1 Z505 F360 ; move Z up stopping at the endstop
G90 ; absolute positioning
G92 Z500 ; set Z position to axis maximum (you may want to adjust this)

Or, if you are using an endstop for the Z axis, you need to define it along with the X Y and Z here:

; Endstops
M574 X1 S1 P"io0.in" ; configure active-high endstop for low end on X via pin io0.in
M574 Y1 S1 P"io1.in" ; configure active-high endstop for low end on Y via pin io1.in

@Phaedrux

So something like the following for homez.g?

G90 ; relative positioning
G1 X250 Y250 ;move probe to center of bed
G30 ;probe bed

Only thing is this lowers the bed down instead of up.

@vishiano I raised the bed and changed a line in my config.g

G31 P0 X0 Y10 Z2.5 ; set Z probe trigger value, offset and trigger height

Now when I run homez.g the BLtouch deploys and I get

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

Phaedrux

Try G31 p25 instead of p0.

If the bed is going the wrong way change the direction of the z axis rotation in m569.

@Phaedrux That did it, thanks for the help.
