Hi, i have problem with simple print for my client. I need to print a socket, like this
and my problem starts, when i print upper part, wall has thickness 0.8 mm in stl file (but it's printed 1.2mm) and looks like this:
It seems that the printeris extrudingtoo much fillament, but... lower part is ok, other prints are ok. Problem occurs when wall thickness is 1.2 mm or less.

I printed a single one at .14 with 100% fan. The wall thickness was still a little off but that's going to be hard to get. .08 is twice the nozzle size but when ABS is pushed out onto surface it flattens out a bit. My wall thickness was 1.15mm You should also set support at 10 degrees. I'm not sure why it is wanting support all the way around. You don't need it. I didn't watch it print so I'm not sure why it has chatter marks.. I'll have to print another..
I've been told this is an issue, with .09 layer have tried thicker walls with simillar failures
Thanks for info, today I reprinted it with ULTRAT at 0.09mm layer. Effect is better, but not ideal.

Also tried today printing at 0.14 layer, and i got similar result as on photo above.
My reseller said thatmost likely, this is a problemwith the project, stl is corrupted, I will try to reproject it in different software.
I imported the file into DS Mechanical and it did detect an error. I converted it to a solid and resaved as STL. Now on 20 degree support is no longer all the way around. I'll print at all default settings and let you know. full infill, .190, normal speed, 20 degree support, fan auto.
I did some tests for myself, to know how to project models to avoid holes,
I made walls with thickness 0.4mm and around, and x2, x3 of that, then seen effects on zcode view,
i found that minimum single wall thickness is 0.45mm, and min. tripled wall thickness is 1.29mm (3x 0.43mm), otherwise there's a space between walls, because printed lines don't overlap
so it's good to make n x 0.43mm walls if that's possible, i.e. 1.29mm wall is good (1.3mm when rounded to 0.1mm), less than that makes hole between,
I found that walls drawn at 0.060" (1.54mm) print as two single filament walls with no infill and space between. At 0.080" (2.0mm) I got a solid wall. So there must be a few sweet spot values for wall thickness in the current Z-Suite.
Did a test print at .09 ABS and it seemed to work fine. Those pics of the prints are horrible. I feel for ya. I'd be upset if I had a print job come out like that.
I did a repair on Nettfabb just incase.
I did change the surface layers to 3 and 3.
I really need to get a better camera. iPhone camera just doesn't cut it or do things justice. Any suggestions? A cheap nice camera that is. lol

I cannot imagine who would say it is a corrupt model... if it was corrupt would it simply not print? and if you change Z resolution it gets better, I have never encountered an STL that was "corrupted" only un-solid which is easy enough to fix.
