I think saying does S3D allow this then No BUT I would setup process for each material and at the given layer insert the gcode manually for change filament and try that cant see why it wouldn't work if you have everything setup like temps and feed

yes please it would be very usefull

I used the BCN with sura I found it had a problem printing spheres, I used there profile but I did my own for the idex which worked well the temp for the parked head was always a problem cura hadled that well S3D struggled you have to write your own script for it to work but tricky.

I've commented before on this subject I'm having to learn Cura to use my UM2 second head, I cant believe how bad it is to use prime tower used when not needed gcode not showing z heights no available cross section view in y x or z direction when you want to place the dreaded support blockers. Slicer...

Just for the Record I'm not complaining, And if there are new features and it is capable of handling dual heads ect, I have no objection in paying for an upgrade.

Totally Agree

what is today may not be tomorrow. I use it but prefer S3D

tried to upload a picture but it wont let me??

spot on its not blobs and zits its it is the scaring I specified a start and end but I have a seam so trying to hide it

You made the right choice terrible company to work with, a very complicated machine and S3D does not work very well with it especially printing cylinders..
