Maybe adding a tool similar to this to the final slices would go a long way.

Way ahead of you. The new upcoming Solus Contour software has a feature to automatically correct optical spherical aberrations. It will be available soon.

Hi you mentioned that you sacle 101.00 0n the value of scale if the model is 1mm off,on the X tab scale but what is its a really small difference like .02mm ?

I wrote about lining of the measurements of a 25mm cube by changing that build area settings. But i there is a problem with this. Yes you can line up a 25mm cube so that the X and Y are correct but this is only for the center of the build plate. If you make a smaller cube like 10mm and place them all around the build area you'll notice the X and Y axis are different for each one of them when you measure them on the quartz. Even if you just calibrated the 25mm cube. This distortion of the build area that is being projected onto the quartz is entirely due to the lens, so you have to work with it. I thought i had fixed the dimensions issue with this test but realized that each individual model needs different X and Y adjustments so you can't just change the build area settings in configure because it affects all the models at once. Hopefully though, there is a fix to this. I wrote a really long post on this, but here's the short.

Since each model has different XY values when you place them all around the build area (even if they are the same model) all you have to do is scale each individual models XY axis in CW. How do you do this? There is a sub menu in "3D View" under "Scale%" open it and you'll see that there are options for you to change the X or Y axis of an individual model. So it's pretty straight forward from here. Need to add or subtract a mm from the X Y axis? > go to Scale menu > Adjust > re-slice > re-measure on quartz > repeat.

1.) Measure the X Y of your models on the quartz.
2.) Go to the Scale sub menu and adjust accordingly. For example if you measure on the quartz a model is off by 1mm on the X axis > go to the Scale sub menu > change the value of the X tab from "100.00" to "101.00" > click the check mark> then re-slice the build area to update the change. Now when you go back to measure the model on the quartz and it should be fixed, if not go back adjust and repeat the process. I went into depth on my original post about this. And don't worry about the warped or stretched look in the "3D View" after you make the changes, it's not what is going to appear on the quartz. Remember that whatever measurements that show up on the quartz is what is actually going to be printed, not the values or look inputted in CW.
3.) Once the XY measurements of the first/second layer are correct on the quartz, the whole build will follow.

NOTE: You don't have to change your build area settings in Configure, keep that at 25 microns. Just scale your models in the "3D View".

This may seem like a hassle to adjust each individual model but it really won't take more than 5-10 mins of your time. Since i discovered this work around all my models have been coming out with the exact dimensions i designed them as. Hopefully this will help you or anybody else out, take care.

PS. I will post pictures if anybody is confused about this, let me know.
