Hello everyone,  
I have a 1 cubic meter home made printer to print wheelchair cushions. It was working very well until now when the Z crashed during the Probe. The probe seems to work well with the QUERY\_ENDSTOPS command; there is indeed the indication open then “TRIGGERED” after relaunching the command and presenting a metal part in front of the sensor.  
I admit I don’t understand where the problem could come from.  
Obviously I have armchair cushions waiting and am in an EMERGENCY!!!

### Basic Information:

Printer Model: Home made  
 MCU / Printerboard: Octopus  
 Host / SBC  
 klippy.log

_Fill out above information and_ **_in all cases attach your_ `klippy.log` _file_** (use zip to compress it, if too big). _Pasting your_ `printer.cfg` _is **not** needed_  
_ **Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there** _

It seem that the problem is the cable. If i change position of the head it works.
