Hello.
Attached 2 photos. This first one if you direct the nozzle to the camera 1 from the parking coordinates. The second is if you first take the nozzle from the nozzle changer from the parking coordinates, and then send it to camera 1. A slight shift is visible in the photo. I do not know how much this is in millimeters, because I don’t know how to see it.

This is normal? Does this bias occur once? Or, in the process of arrangement and movement between feeders on different sides, does the bias accumulate?

Nozzles from the nozzle changer are taken and installed perfectly.
The shift occurs if after parking it moves to any distant position. For example, go to the edge of the eastern feeder, and then move the nozzle on the head 1 to camera 1. If there are several such movements, between camera 1 and the edge of the eastern feeder, then the offset does not increase.
Should it be like that?

I would also like to be able to choose the movement to the desired position of the nozzle on the head 1 or 2, for control. This feature is available only for the lower cameras and marker points, but not for the viewer and components on the board.

I will try to explain the sequence of actions.
1. I take the nozzle in the nozzle changer with head 1.
2. I select the Reset_XYZ menu to go to the parking position.
3. I transfer head 1 to camera 1. A command from the menu.
4. I turn head to the most extreme east feeder. (near vibro feeder). By clicking on the button "Move to pickup" in the settings of this feeder.
5. I transfer head 1 to camera 1. A command from the menu.
6. I get the offset shown in the first post.
If then repeat sequence 3-6 several times, then the offset does not increase.
What can you say?
