(Linear Tool Changer (Type 2))

It would make the most sense to have racks setup either in the rear along X or on the right along “B/Y2” The reason being you can setup your soft limit to exclude that as travelable area, but it would still go there for tool changes. I have not tested this with the tool setter, but I am prepared to do it, as I have my tool setter setup on the right side, but I also home right, so I don’t know what’ll happen. Thats for this weekend to find out.
The following is my demonstrations, and findings, and it can be any number, thats why I annotated it as positive / negative, and 0.

0, 0 / 0, 0 results in a up down motion which is for the current tool racks

0, + / 0, +
-, 0 / -, 0
+, 0 / +, 0
+, + / +, +
-, + / -, +

Based on the above listed information:
0,+ / 0,+ = along the X axis, Y = 0
0, - / 0, - = along the X axis, Y = rear
+, 0 / +, 0 = along Y, X = 0
-, 0 / -, 0 = along Y, X = far right.

Tested the racks being outside the soft limits of your machine, and the tool setter as well

Tool setter would result in an error, wont even head that way.

If your homing location is where the soft limit is, you can jog around there, but once you’re inside the workable area of the limits, you can’t go back.

Tool changes worked as expected per documentation.

For doing this, your racks will need to be on the right, or on the back, or technically both.
