Describe your issue:


I was ruuning my enderwire very smooth untill it come to error when using CR-Touch…when i turn-on, the procedure is ok (down, up, down up).
When i test the command via console (pin_down/pin_up) it work´s ok.
When i try to perform home all, the XY axis home ok, but when Z, probe go “down/up/down/up” and try to touch (but it´s retracted), then colide to the bed, and i have to hit the emergency button to not damage other parts.
For me it´s a critical fail, and it´s not related to hardware…something change in klipper recent update (it´s the only than i changed recently).
Please check this information and answer ASAP.

Many thanks


For things like this we really need the klippy.log to have a better view on what is going on.
