Hi, this is our first post. Any help would be greatly appreciated.
We are printing in PLA and on our ultimaker 2+. We are having problems where the printed material doesnt stick to the bed effectively. This only seems to happen to the centre of the bed.
Any suggestions welcome. We have adapted the bed, changed nozzles, material etc and various other changes. Is this a common problem? Its almost as if the print nozzle moves around too quickly.
