MMU2 N/A on support menu

Hi,

I have a mk2.5/mmu2 which I build up from a mk2s/mmu1. I used the printer for two days without problems after finalising the upgrade. I use the latest firmware. Today after startup it could no longer find the MMU2. Normally when the print starts up the MMU2 activates the two mmu steppers and allows the filament to load. Now the MMU2 is now longer recognised. The support tab on the screen states MMU2 N/A. The MMU2 board is still powered and the leds are all flashing red.

Is this a known issue? Searching the forum I did find at least one occasion where this problem seemed to be described. The post was without a solution though.

any information would be appreciated ...

thanks

jan
