Non heated/ Cold Nozzle while Automatic leveling

[cjs 34]

May it be possible to add an option to disable the nozzle heating up to, I think, the waiting temperature of the loaded material?

I know it’s heating up to account for thermal expansion as well as filament still left on the nozzle, but a hot nozzle limits the use of the automatic leveling to specific surfaces. 

Being able to do cold probing may allow to use the automatic leveling with Ultimaker adhesion sheets or other adhesive sheets. 

What do you guys think about it ?

An interesting idea. It could be done in a way I'm currently thinking of, but I will pass it on to our PO.

Thanks for looking into it @Marco_TvM ? 

May I ask what PO stands for ??

I believe that when no material is set for an extruder, the nozzle stays cold during the active leveling.

But you should know that it is heated to flatten possible plastic remains below the nozzle. If those plastic remains are cold and hard, the outcome of the active leveling procedure will get an offset, causing the nozzle to be too high during printing.
