I'm having the same issues as described above. Same parts different areas of the bed different results. I'm very unhappy and wish I would have selected a different printer. From reading the forum I believe that the S5 is not worth the extra money. There is something wrong with the design. I have to do a lot of testing using the scaling tool with the part in a fixed orientation. My friend has a 600 dollar printer at home that performs better at dimensional accuracy. I don't recommend this printer to anyone. The x axis is always smaller than the y. Turn the part 90 degrees the x is still smaller. Two identical parts two different sets of results. I'm talking about .5 mm differences. I want to make prototypes that turn into production. I can't be customizing the models just to get a decent print. The Material Station and Air Station work well but the printer is below average. I can't count on getting a good print and have to print the same part multiple times to get a result that is good enough. Again stay away from the S5.

In Cura and the Marketplace Setting Plugin I found the X, Y and Z MM per step settings (50 steps per mm). As my print is off by .004" (in many material types) in Y why couldn't I just change the step setting to 45 or 55 (.0007874 inches per step) to make the correct .. It looks like I could make this change and save in my profile. What am I missing??
I realize I could scale my part by ~1.2% in the Y directions also.
Again why could I use the step settings to make the required correction now and when the machine starts showing signs of wear.
I have a brand new Ultimaker S5 Bundle.
Thanks for any response...

A few weeks.
My primary requirement is to producing working prototypes before committing my designs to traditional fabrication. It's not a good workflow for me to create models for printing only.
I'm printing a test part 50 mm x 50 mm x 25" tall. No mater the material and using the using Ultimaker profiles. The X is always smaller than the Y. The only solution is to play around with the scale tool in one axis (~.7%) to get a square part. It is very consistent It's firmly my belief that the factory calibration of stepper steps is incorrect. Using scaling in X by .7% and the other expansion settings I've been able to make better parts in the center of the bed. I also can't print multiple parts of the same item as they will never match unless I keep the same orientations. Again I'm very disappointed but need to move on. On balance I like the printer and am resigned to scaling every part in one direction. I worked with support and although they were friendly and helpful there is not much they can do about a poor factory set-up aside from the hassle of returning the machine. I write this mostly to warn others to not consider the S5 if you expect good dimensional reliability. From my experience and others on the forum this seems to be a accurate assessment (including a co-worker with a 600.00 printer at home). The Material station and Air Station work well and are a great features. The belts are tight as are all the shafts. I realize the materials make a difference as do the settings. I've been using measuring tools since 1977 starting out as Tool and Die Maker, machinist, cnc machinist and now a design engineer know full well that I can't apply the same standards to a 3D printed machine. I'm not measuring in the corners but in the most stable part of the print. I do believe that I with a square part I should get better matching results (.35 mm over 50mm).
