To expand a little on my idea and I run into this daily!
I get a job that is let’s say 13 parts. All parts need to have the same settings such as layer height, infill etc.
I load all 13 parts to group1, set my options as needed to affect all 13 models as a group - nice feature!
Now the issue is, some of the parts are large and print one at a time but others are small and can be printed in a group.
So, I can select which models to print in a current run - save gcode - then go back and select other ones and make a second run etc. saving all the gcode files off pretty easily.
Currently I have to load (in S3D) the ones I want, send to print. Delete them then load another group. Kind of a nuisance!
Maybe one day it would be a cool feature. Load all 13 models, changes settings once for the group and then you’re ready to start slicing!
