interestingly enough there is actually a PDF file of what others have used with S3D on the lulzbot mini and ive read threads that these are good starting points. but, with that being said the above prints were done that way and they dont look so great so i will take the collective advice of the board and attempt to start from scratch on the S3D supplied Lulzbot Mini profile.


the one thing i saw, not sure if this would affect anything but, was the starting of the gcode that S3D uses on their lulzbot mini profile versus what CURA uses. would that affect anything there, especially the G21 code specifically jumped out at me.

you cant just copy paste setting from one slicer to another. with some settings that may work here and there but every slicer is totally different. there is math in figuring out everything so s3d's algorithm for figuring extrusion rates or whatever is not going to be the same as another piece of software. you need to forget cura and make your own profile. you cant really expect built in profiles to work in all cases either. there are just too many variables in 3d printing for a single profile to work with everything. on a closed system with material control like stratasys then yes because you are using their materials and they know how everything works with that. home based machines..no way.

Ok. When you say copy and pasting settings shouldn't be done. I'm assuming you're referring to the .FFF settings within S3D, not the gcode settings that I just posted above. I was under the impression that the gcode could be used from one machine to another without issue.

Yes not the gcode but your fff settings. People always seem to have more trouble with s3d when they come from another slicer rather than start their 3d printing career with s3d. Settings and values almost never transfer over.

ok, i will take a step back then next time i get to sit down and play with the printer and start from scratch with S3D and see what happens.
