Disappointed S3d
After many years I'm starting to get fed up with S3d and I'm starting to experiment with Prusa Slicer , wanting to print a large model with TPU I encountered the problem of the top where the model causes the head to snag on the print and rips it off the table . I came up with the idea that I will turn the model upside down and before the end of the printout instead of the bridge I will put the printed potpore and print the rest on it instead of the bridge. And here my question is this model which is in the picture was to print with nozzle 1mm bontech lgx extruder for flexible materials 27 hours and when I started to combine, the time increased to 70 hours and I can not shorten it even when I increase the speed to 100mm sec can you see what is going on?
Please help best regards Bart
