Problem with printing - nozzle print dont touche plate

Hello,
I have a problem with printing. Before the problem, I heard on the guides that they are walking a little hard so I sprayed them with WD-40 and it was ok. After autocalibration of the table as before every print, everything was at 0.00 but when the printing started after the rafts which came out well, I think the table has dropped because the material was printed on the fly without even touching the table. What can this be caused by? I will add that I tried an earlier print that came out well but now is the same error. Please help.
