Robus 600 not closing fully

[All Well]

I have a RB600 sliding gate installed working ok past one year. Lately noticed not closing fully, about an inch shorter than the mechanical stop. Have run the 'Recognition of Gate Length' program without resolution. 

Any suggestions on what next?

Thanks

Hi,

thanks for the message,

what is the Bluebus LED doing when this occurs? it should flash red and pulse an allotted amount of times, how many times is this flashing?

Bluebus LED is flashing normally. L1 and L2 flash normally. When i press Open and Stop together L1 and L2 flash quickly. When buttons released L3 and L4 flash and I press Stop and Close buttons. The gate opens and closes normally as per the videos. But when I operate thru remote or fixed button the gate does not close fully, stops about an inch short, Because of this the small manual gate does not latch properly.
