PLA not sticking

[tom10122]

I really have no idea what happend, tried printing out some linear bearings tuesday and it hasn't stuck since, same kind of tape as always, bed level, tried different heights, My temp has stayed the same. I was printing nonstop for a week with no problems whatsoever so I am really scratching my head

Changes in ambient temperature and humidity can make a difference, usually it's just a question of bumping the bed temperature up 5 degrees.
You should also recheck the height above the bed for 0, endstops tend to drift.
