What is the difference in Bed Profiles?
When in settings you can change between textured and smooth, but what difference does this actually make?
The different coatings are of different thickness so each is associated with a different first layer 'Z' offset. If you tell the machine which sheet it is using it will use the stored value for that sheet thus saving you from recalibrating every time.
Cheerio,

Is that not the point of the PID?
RE: What is the difference in Bed Profiles?
PID Tunes the heating process to the heating components in use. you can PID Tune the Extruder, and heatbed separately,
If you regularly use high temperature filaments, you are best doing the PID at the higher temperatures.
Some folk, add the PID values to the Filament Custom Gcode, start gcode, in preference to using stored values
the Pinda locates the extruder at a safe height above the build plate after auto home. then the Live Z saved value lowers the extruder to a satisfactory height (After interaction with the user) to provide a good first layer.
Live Z is likely to be different for each build plate

Pinda was the word I was looking for. I still don't quite understand, how does the satisfactory height change? Wouldn't it always be X amount of space above the printbed making the live Z always the same?
RE: What is the difference in Bed Profiles?
Because the Pinda measures the distance from the heat bed, not the build plate and each plate (even of the same type) can be just different enough in thickness that it matters. And different types of sheets can/do have very significant differences in thickness.
RE: What is the difference in Bed Profiles?
the pinda, senses the surface of the metal core of the heatbed.
A satin build plate has a thin layer of powder coat paint covering the surface,
A textured build plate has a thicker layer of powder coat paint covering the surface, and the first layer squish, needs to make the molten plastic, fill the texture pockets
A smooth build plate has a layer of Double Sided adhesive sheet and a layer of PEI Sheet, on each side
the net result is that the surface interface between the filament and the surface coating is progressively further away from the steel core from the satin build plate. to the smooth build plate.
so on the same printer, with the same Pinda, at the same temperature, the ideal live Z for a smooth build plate will be a smaller negative number than the ideal live Z for textured or Satin build plates.
Personally, I don't use the build plate definitions, i just adjust live Z when I change the build plate.
