IDEX/multi extruder auto calibration
-
Hi I want to cut a circular feature into my build plate. The center point will be a known location. The build plate will be connected to 3.3v and both nozzles will be connected to an endstop signals. Using really slow movements I want to use each nozzle to probe the sides of the circular feature to find their offsets.
I need a way of recording the distance between the endstop being triggered the first and second time on X, then the distance between the first and second time on Y. Then I need to do maths on these values to find the offsets, then I need to use these offsets and apply them in the firmware.
Both E0 and E1 will need offsets stored since they will be relative to this feature.
This feature will usher in a next level in multi extruder print quality and ease of use on the duet. It's importance cannot be understated given the incoming era of multi extruder machines prusa is kickstarting.
The next step is enabling nozzle lifting on the second nozzle, but that is for later.

@droftarts Actually, that does exactly what I am looking for. A while ago I read the entire gcode dictionary for the duet, and since I did not see any similar posts on the forums I assumed it was not added yet. This makes things easier for me!
