Prints not sticking on bed centre

Hey all

For a few days now my taz 6 is giving me a hard time. Anything i print in the centre of the bed it will not stick. Anything above, below, left or right is fine. Which is annoying if something is spread across the whole bed.

I’ve taken the bed glass off and it is flat, even adjusted z offset to see if that helps and no luck there.

Does anyone have any other ideas as to what it might be??

Hello Stevo

It sounds like you may need to clean up, and possibly sand the PEI surface. We have a great write up on maintenance here:

Sorted… quick wipe over with an alcohol wipe and we are printing again

Thanks for help
