read out height of extruder
Would there be a way to read out the height of the extruder?
Situation: My delta is to big to work with a normal bowden extruder. The delays get to big. I ordered a flex3drive which is a kind of direct drive with a flexible driveshaft. The motorside of the driveshaft is mounted on the side of the printer the other half on the extruder.
Problem: the shaft has to be as short as possible.
Solution: let the motorside of the driveshaft folow the extruder (vertically) so it stays all the time at the perfect height for the extruder. For that i would need the height of the extruder (or even better, get a drive command for one of the extra steppers :-)
EDIT: This would also be handy for people who wants a floating bowden setup on top of the extruder. In this way they could pull up the bowden setup when the extruder goes up and keep their bowden line as short as possible
