Thanks for the insight. I think maby my pov was to much from my own printer (Big Builder).
My printer has in fact only one head, but dual extrusion. And it works pritty well!
For the bottom and top layers I had the same thought. You still need a wipe tower.
But for some prints like embedded letters it would be an interesting feature.
But seems to me that there are to much conditions (especially single head dual extrusion) to even get a feature like this in the software :-).
Maby I can program it myself? Selecting another extruder for infull can not be so difficult?
It's only the order of printing that seems more difficult to me...

Hi Jeroen,
I think the time you would waste for waiting for one head to heat up and the other to cool down would massively reduce the potential gain in time one could expect.
The extruder wont be wiped already. It will need to wipe while its doing the fill and will cause under extrusion when cooling down. What do you do for layers having the top/bottom fill? You can't wipe on those. If you cant wipe on those then you still need the tower to be at the good height for those cases.
In other words you will always need some place outside your model to wipe regardless of the available fill.
How can single head dual extruder even work?
Are you saying switching filament from one to another above the nozzle and use the same nozzle? Then its worst than wiping. You would need to purge the entire nozzle chamber from the previous filament before starting to print again and that will mean wasting a lot of filament. It would also mean you bring hot filament into the bowden tube which will most likely get stuck in the bowden tube while cooling down,
I might just dont get what you are saying.
