I'm relatively new to 3D printing. Done quite a bit over the past month or so but am still learning setting etc.

The item in the attached photo was printed on my FlashForge Adventurer 3 printer.

95°C bed temperature
135°C nozzle
ABS
.4mm first layer
No raft

As you can see in the photo the bottom layer(s) moved during the 2.5 hour build. I think it was probably caused by my increase of the first layer from .28mm to .4mm but would like to hear what others think. Bed too hot perhaps for such a long construction time?

Thanks,
BH
