[Ultimaker S5 - one material appears to be empty]

Hello,

 

I have the same problem with my Ultimaker S5.

I tried all the above but the problem still, remains. 

I used PVA material as support, but although I removed it and I worked with only one nozzle with PLA material, I cannot finish my print.

I do not know, if that is the cause of the problem but it started after I performed a XY offset calibration. 

I use the current firmware 5.4.27.

The problem is serious and make the printer useless

Is there any solution?

 

Thank you
