Nozzle offset probe failed

[hussainsail2002 3]

Recently Bought 3 Ultimaker 3 3D printers....

 

Having the same issue on all of them.

 

I am unable to calibrate the X Y offset as it gives me the following error

 

Nozzle offset probe failed. Please check the nozzles and bed and try again.

 

The bed seems fine as single extruders are working fine and sticking correctly. I have changed the print cores , and tried.

 

Also the extruder 2 does not extrude any material during the X Y calibration, but prints fine by itself. when the print core is changed , the extruder 1 does not extrude.

 

I have the latest firmware installed.

 

I am having the issue on all 3 machines.
