Hey Bracco, I have downloaded your script and tried using it on a print. I have T Rex 3. This works great for the first couple tool changes, however, it reaches a point ( generally after 2 switches) that the script no longer seems to change anything, and the extruder extrudes a little material on the part printed by the previous extruder. I'm using:
Remove Layer Start X/Y : TRUE
Working mode : Auto Park
I have set my Z seam X and Y to the same for each extruder so that the values are the same for each layer... is that the right setting you mean?
thank you so much!
