The item uses the full width of the plate - I have never had an issue with smaller prints and the inner parts of this are fine. The A1 is as delivered.
I am using a .2 hotend.
Both ends are lifting off the plate about a centimetre from the end.
Any suggestions are welcome.
Hi
In my view, it seems wrapping.
There are many ways to workaround, but if the problem is new, you may try to look for what has changed.
The issue relates to material contraction when cooling.
Wild guess from your comment:
- nozzle diameter smaller(as you state 0.2mm), and thus thinner layers → try a thicker first layer height and print slower; Assuming that you are using PLA or PETG and not more demanding materials as ABS.
Generic causes and solutions:
- fast cooling —> increase 5ºC the bed temperature and assess if it helps; avoid air significant air drafts;
- bed adhesion —> ensure that the plate is properly clean, that the bed is calibrated, and if necessary, use some adhesive material;
If it still wraps, you can try to add some “brim hears” to the slicer that will add some extra adhesion material to the corners.

Thanks for the response. After researching the internet and looking at your suggestions, I bought some adhesion spray 3DLAC - the resulting print was perfect.

I would just say: a clean bed would have solved the problem.
I have had once a problem like this - after cleaning it was gone. I used a spray for TPU - but not for PLA / PETG.
