Good Afternoon!
Have an interesting problem cropping up for me here. I've spent the last few days digging around the internet, and I haven't found anyone with quite the same problem I'm facing.
When printing, things that should print square, like a Calibration cube, are not doing so. I'm seeing angles that are NOT 90 at corners, and a strange outward bow on all the sides.
However my Eris, right next to it prints very square
Here is a pic of two Eris cubes side by side to show how square they are
Here are two from the Orion in the same positioning
I was trying to print some puzzle pieces when I first noticed the problem. All of the green pieces are from my Eris, using the exact same STL, all of the Blue are from my Orion:

Re: Orion Prints not coming out square
I have updated Firmware, and gotten the latest software I could for it.
I have attempted to calibrate it myself, and I have also run gCode G29 to calibrate it (That usually works better than what I can do by hand)
Here are a few pictures of the settings I am running currently: I am using Matter Slice as my slice engine, mostly because it allows me to alter a few more options with infill. Using a pretty standard PLA for the printer.
I am currently printing a large, flat hexagon to measure distance to towers (I'm not sure that will help anything, but I assume if it is not equidistant from all points, that it could lead me to discovering an issue) and I can also measure to see if all the sides are the same length/parallel with one another.
It seems like all of my belts are nice and snug, and everything else that moves SEEMS to be in good condition and moving well. I'm not sure in all cases, but on brief inspection, it looks good.
I am also suspicious that my glass might be slightly uneven as well, as when it is putting its first layer down on the glass, there are some spots (small, and possibly in the same area every time) where the filament doesn't quite make it down to the glass... something like quarter sized spots.
I am open to any thoughts or suggestions at this point. Thanks!

Re: Orion Prints not coming out square
Check your platform for play. Are you using a printed platform? If so, consider replacing it with a machined or injection molded one. My V2 would print out a 100mm calibration block with the center measuring 10mm, the Z end measuring 10.2mm, and the Y end measuring 9.8mm.
Replacing the platform with a new injection molded one took most of that error out of my prints.
The block that I was printing:

Re: Orion Prints not coming out square
No problem! For me, replacing the effector platform helped quite a bit.
I hate to say it, but my Tronxy A8 clone beats the pants off of my Rostock when it comes to build accuracy.
Edit: By the way, check your belts for tightness. I can see where that would cause mushy corners.

...then there's something mechanically out of whack with your Rostock.
