Yes that is a great feature allowing to review previous print profiles, but I see it "only" as a workaround. But at least it is possible to do it this way, assuming the full profile is stored in the gcode file.
I am a friend of clean solutions, and in that world the best would be to have it implemented in the application. So one would always have the latest profile if evere it would be changed for some reason. Also this should not require much code to be implemented as most bits are there already. - Just a suggestion
Not sure if I will ever require this but, if so I will for sure remember your words So if I get this right the nozzle opening is 0.4mm, if one chooses a shell that is not a multiple of that size but larger than it it will result in one path to have to be printed in a 0.4-0.8 width which is achieved with over extruding and the overextruded material flows under the noozles flat end achieving the larger width. So the theoretical limit of this is the width of the noozles flat end (not speaking of quality here).
No worries, I understood from your initial post that this could work but that it would not be th ebest choice for me to go that way if it can be avoided.
P.S.: As said before, I am still waiting for my printer to arrive But I am convinced already that I did the right choice, seeing the speed and valuable information provided in this forum from the community and Ultimaker Staff. This thread could have ended in post #2 (well #3 for the "Thanks") with something like "This is probbaly a typical noob error, you forgot the initial layer thikness". No, not only got I this information with a high detail, I also got many valuable additional tips around the topic.
So let me thank every poster in this thread for your valuable help, which is really appreciated ! Unfortunately this forum lacks banner smileys like "Thanks", "Great Job",... I would use them all
