I can't get the Bltouch working

Sorry, but I'm kind of out of ideas at this point anyway.

All I can say is go back to the beginning. Double check wiring. Follow those guides.

It weird that the probe is the only problem

Do you have a mechanical end stop to use in the meantime?

It's possible that your bltouch is damaged.

You could try cleaning the pin. There's a set screw on the top to remove and adjust the pin.

I have a different BLTouch I can try. How do I add a mechanical end stop to Z. I don't know how in the firmware.

Thank you

I have the BLTouch on the machine just unplugged I will let you know how it goes. Do I just go back to https://configurator.reprapfirmware.org and redo the whole thing. or is there a quick fix.

Phaedrux · 8 May 2018, 17:31

No you don't need to redo the configurator. You should be able to just plug the new bltouch in and see if it does the same thing.

I did that it does the same thing X and Y home and with the new probe does the same thing as the video.

The probe of the BLtouch shouldn't do the dance move (in&out) all the time.
If this still happens with your new BLtouch you really should check the wiring and configuration again.

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
for Retract: M280 P3 S90 I1

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.

Now for some reason I can't get in the wifi web page I have tried everything. Pronnterface work with the plug in and YAT. The Wifi light on the wifi board is on without turning off solid blue. I can turn it off with YAT and back on then solid again. I can't get in the Duet page with the wire pluged in.

Saltypetz · 9 May 2018, 13:45

In Pronterface face it moves x and y all homes Z stops before bed then probe up and down. I still can't in the wifi. I tried all the comands.

Just got back in something happen to the sd card all the files where gone just get in back on line.

Saltypetz · 9 May 2018, 17:30

I must be getting close. I am going to post a few pictures. There is one problem I never had I home X and the motor keeps running like the endstop is not working.

All you have to do is add this to chrome and you can see the pictures.

I really think it is something in my setting. I copy the other tevo black widow and tried it and it didn't work.
