>on one side I get a posetive band on the other.

Hmm. strange. A clue. Could be hardware then. Loose belts (play aka backlash) could explain this actually. But I still think most likely software.

>so i dont save out the Gcode.

I think cura saves it regardless. Somewhere. Not sure where.

Well just reslice the same part then with the same settings and look at the "layer" view. See if the same "shift" is in the gcode.

What I was talking about (fix horrible discussion): Some models violate rules of having one inside and one outside.

For example lets say you have a cube and then add the letter F on the side. In the cad you might create these seperately then select the F and place it touching (and slightly inside) a face of the cube. Some cad will do a union and remove the extra walls at this point. Some won't (e.g. sketchup won't). So at this point a ray (a straight line) passing into the F will pass through the wall of the F, then the wall of the cube, then the back of the F, through the majority of the cube and through a final wall a the back of the cube. What is cura to do? There are two external and two interal walls here. SHould it make part of the cube hollow? Or should it union it all together? That's what those "fix horrible" settings are all about.

Often the part looks fine when you load into cura in normal view but when you look at "xray" view you can see these internal messups and when cura slices there are "shifts" or "holes" or all kinds of weirdness.

>printed with a 1mm wall

What? Skin? Or is it 1mm in the STL? There's a big difference. The skin setting works best if it is always a multiple of the nozzle diameter (.4mm) so 1mm skin is going to overextrude the inner pass which is messy. Better to do .8 or 1.2mm skin (2 or 3 passes).

1mm STL wall is even more complicated so let us know if that model has a 1mm wall.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
