I’ve installed bltouch clone (3dtouch from aliexpress). I am having issues setting it up. I’ve followed instructions from here. Problem i am having is that i cannot do auto home. After executing G28 printer is homing x and y, then goes to the middle:

  • lowers probe of 3dtouch
  • start lowering head
  • probe touches bad surface and retracts
    after that i get an error:
12:52 AM
Failed to verify BLTouch probe is raised; retrying.
12:52 AM
BLTouch failed to deploy

Also sensor is going into error state after it is triggered (red led is blinking).

I’ve tested it manually, you can see from the logs that commands pin_up/pin_down are working, also QUERY_PROBE is returning good results. When i lower the probe and touch it, it goes up, QUERY_PROBE is returning TRIGGERED but red led on 3dtouch is blinking and it won’t accept any new commands until i reset 3dtouch.

I had to use probe_with_touch_mode: False because if it is true when auto homing it crashes into bed.

I’ve also played with pin_up_reports_not_triggered and pin_up_touch_mode_reports_triggered , tried all 4 possible configurations and results are the same.

To me it seems the issue is sensor itself, but maybe i am wrong, did anyone had similar experience/idea how to solve this issue.

Thanks
