So ran into an issue on my new A1 with warping. Investigating the problem, I saw a HUGE difference in the default bed temperatures for BL PLA basic in the A1 and P1S.
The default for the P1S is 55 C for all layers. The default in the A1 for the SAME filament is 65 C for all layers. So the factory defaults for their own filaments are different.
I’m going off the fact that since their own defaults are different, they decided you have to establish a different custom profile for each printer when using the same filament.
