    There is one problem I never had I home X and the motor keeps running like the endstop is not working.
    I just can't get the BLTouch right really need help.
    I know I am real close.
    All you have to do is add this to chrome and you can see the pictures.

      So that's two problems then?

      Test your X endstop as described at https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Test_endstop_switches.

      The first image on dropbox indicates that you have the Z probe type set to 0 (P0 in your M558 command). If you are using 1.21 firmware, it should be P9 for a bltouch.

      btw you can show images that are hosted on Dropbox inline, by putting them between img tags and replacing ?dl=0 at the end of the URL by ?raw=1.

        Now I have every home but the BLTouch I am a newbie to this board and a little lost.

        This is in my Config.g

        ; Axis Limits
        M208 X0 Y0 Z0 S1 ; Set axis minima
        M208 X560 Y250 Z400 S0 ; Set axis maxima

        ; Endstops
        M574 X1 Y0 S1 ; Set active high endstops

        ; Z-Probe

        M307 H3 A-1 C-1 D-1 ; BLTouch
        M558 P9 X0 Y0 Z1 H5 F100 T2000 ; BLTouch used by Z axis, dive height 5mm, mode 9
        G31 X0 Y0 Z1.53 P50 ; Z probe trigger value, offset in relation to nozzle. And trigger height adjustment

        My deployprobe.g

        ; deployprobe.g
        ;
        Probe deployment routine for BLTouch
        ;
        M280 P3 S10 I1 ; Set servo position to deploy

        My retractprobe.g

        ; Probe retraction routine for BLTouch-Smart Tevo black widow
        ;
        M280 P3 S90 T1

        I setup the sd card like this link.

          I suggest you test the Z probe configuration as described at https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe.

              @saltypetz do not use photobucket, its crap. Don't force people to install chrome extensions.
              imgur and similar others provide better service

                        I did this and it worked perfect. When I do the G30 I get this.
                        Now issue G30 command.

                        G30
                        Error: Z probe already triggered at start of probing move
                        It moves to center of bed and only the red led is on then the red and blue come on at the same time and i get the error.

                        Herer’s a simply macro I named Move to Centerbed, where I home X and Y first:
                        G28 XY
                        G1 X100 Y120 F4000 ; Move probe to middle of bed
                        Move Z untill your nozzle is about 10cm (4 inches) from the bed.
                        Be ready to click the Emergency Stop in case the probe misbehaves.

                          Your Bltouch Z-Probe value shouldn't read 1000 all the time in the webinterface. Maybe you have a bad contact in one of your crimped contacts/wires or you missed to set your bltouch to the correct voltage by cutting the pcb line or adding a resistor.

                          As I have mentioned in your previous thread:
                          The probe should move two times out&in when the printer is powered up, then it should stay rectracted (in).

                          If your BLtouch does this fine the next thing to check if you can manually deploy and retract the probe with the commands:
                          for Deploy: M280 P3 S10 I1 ;(and it should stay deployed - not changing in/out by itself)
                          for Retract: M280 P3 S90 I1 ;(and it should stay retracted - not changing in/out by itself)

                          My BLTouch Z-Probe is always shown in the webinterface with a value of "0", but it works fine for me. As it is mentioned in the guides, the value may change so fast when probing that it just isn't displayed when it is triggered.

                          Is this is all working for you to this point ? This has to work before trying to probe the bed makes sense.

                            I didn't cut the wire to put a resistor. I am going to try your settings right now.
                            This board is a pain but I'm sure I will love it when I get it right. I have been trying so hard
                            for 3 weeks now. I get so mad I want to throw it in the lake. Just kidding. I love it and wish I could get it going.

                            Thank you
