Probably not, changed it back...

For the bed, use:
Bed: M303 E-1 S60 C8
and save bed settings with:
M304 P1 I2 D3

Maybe this happened after I reflashed the firmware (with this https://github.com/mlaws/solidoodle2-marlin ).
Are there some firmware settings which could affect this? I can post them here if I'll know what first.

It seems constant judging by the number in Repetier Host. But I don't know how often that number is updated.

Is the bed temp constant or does it fluctuate a lot from where you set it?

I can only find info on tuning the heater of the hotend, not the bed. How do you do it?

I'm currently experiencing extreme warping with any size object in any place on the bed with any temp I used before (90-110), with either (the same) hairspray/ glue stick and the same filament.
I recently replaced the fiberglass mat on the bottom of the aluminum bed (put the old one back because of this) and reflashed with the official Marlin firmware so maybe I messed something up I'm unaware of.
