First thing: I posted this in the software subfolder on this forum first, but this seems to be the better Place. Please delete the other one.
Hi, I am trying to print a vase using automaker.
I found the file rbx_vase.stl on the medium that came with the printer. The best Result I was able to get up to now was using the cura engine, but the slicer seems to think that it needs to add material in overhanging areas, which ruins the nice look of the vase. It puts a second perimeter only in these areas. !Not nice!
My aim is to have a 0.8 mm thick perimeter that is only one perimeter thick. 0.8 because of the 0.8 nozzle. I would like to go to a layer hight of 0.8 mil but it seems it won´t let me.(maximum of 0.3) I even tried the advanced spiral setting using both the cura and slicer engine but it only printed the bed and started to go crazy afterwards on both. Slicer also does not seem to be happy with one perimter of 0.8 with at all because it printed only a very very thin structure with holes in it. I hope you can repuduce my problem with all these informations. I investigated quiet closely on the subject, but found no solution.
Thanks in advance from Lahminator.

@lahminator what version of Automaker are you using. There is a bug in the beta AM2.00.01 that means it doesnt work with the 0.8mm nozzle.
Also, of you could set the layer height to 0.8mm (assuming you dont mean really mean mil) the layer bonding would be rubbish. Imagine stacking 0.8mm circles, the contact arrea would be infinitesimally small. It needs to be somewhat lower to squish a bit.
Which nozzle was it printing with?
Did you copy your profile from the Draft profile?
Sounds like everything should be ok. I havent tried a single perim vase on the Robox yet and dont have access to the machine at the moment. Hopefully someone else can give it a quick test. Its a CEL model so there should be a good way to print it.
Ok, im a bit clearer now. Spriral prints are not possible on the Robox currently. Im guessing you must be manually editing the profile in a text editor to select it. What happens when you do this is probably a bit unpredictable. Best bet would be to add it to the feature request thread.
To get the cleanest possible z scar currently you need to calibrate the nozzle valves and also measure the exact diameter of the filament.
@lahminator i understand your annoyance. Remember that the kickstarter video was made during development and not everything makes it through to the final product(lots of them dont even deliver anything at all). I expect its a feature they would like to add at some point, but doing so comes with a certain development burdon. For every new release they need to backward test all the various features to ensure they are not broken. Its a big ask for a small team. They nearly dropped slic3r to concentrate on Cura at one point, but didnt due to feedback from customers(slic3r is better at small details), so they do listen and take customer requests seriously. The robox is truely great at many many things, but yes it lacks in some of the more advanced slicer features. Hopefully CEL will grow and be able to expand on the current feature set more quickly in the future.
I had a bit of a internet search and it seems that the Cura spiral mode isnt great anyway and still has steps in it. I tried this on a reprap printer using slic3r. And couldnt get it to work either.
What 3d printer have you tried that will print the object?
