Enable Wipe Tower with 2 different Materials/ Extruder
Hi!
I believe some of you may have encountered this message:
"The Wipe Tower currently supports non-soluble supports only if they are printed with the current extruder without triggering a tool change. (Both support_material_extruder and support_material_interface_extruder need to be set to 0). Shall I adjust these settings to enable the Wipe Tower?"
Currently, I am printing without a Wipe Tower because I am unable to print with different tools for various tasks (Perimeter, Infill, Support, etc.).
What am I doing wrong? I am quite sure that this was possible in an older version of the slicer.
In this particular case, I want to print a support structure in PLA and the part itself in PETG.
This setting would also be important for printing with water-soluble supports.
Printing without a Wipe Tower only works to a limited extent. The printer produces too many strings, and the print is not perfect.
Ideally, there would be a separate Prime Tower for each material.

I realized I forgot to set the Top Contact Z Distance to 0 (soluble), so that was my mistake.

Apart from that, I set the wipe tower extruder to the PETG tool and add a few extra mm brim to the tower. This is 100% necessary for bigger prints, otherwise your PETG purge lines will not stay within the tower & the tower will eventually collide and be dragged around.
Make sure to create a PLA profile with bed temp = PETG temp. If you just use your normal PLA profile and increase the temp without saving, it will ignore that setting and the tower/print will come loose because it cools down when PLA is active. With these little changes I get fantastic surfaces reliably.
Very similar scenario to your print (frame with supported overhangs, but I'm using custom supports with solid top layers for better surface quality): https://www.printables.com/model/845676-low-profile-sbs-adapter-for-capillaries-and-nmr-tu
