Part of my challenge has been translating the advice from people that use other slicers into stuff that makes sense for Simplify3D which is what I am using. So I asked for help on the user forum for Simplify3D. Someone pointed me to an option called "Horizontal Size Compensation". It takes a number of millimeters (+/-) as an input but frankly I was not sure how to use it...and assume that it would be better if I tried to calibrate things the "right way".
More fool me. I finally decided to try it and found that it ... works? Below are a sample of the results that I got on my first couple of tests:
The first test was for a spacer that will hold an 8mm nut. As you can see the print without adjustments was too small. The print with a -0.1mm compensation was perfect. So I thought that I would try a bigger and more complex piece and printed a #3DBenchy with the same compensation not really knowing what to expect. As you can see, I got the same kind of positive result.
Am I missing something? It seems a little to easy. This is a feature that has been in Simplify3D since I bought it a couple months ago (not just since the upgrade to 3.0) so I really should have tried it sooner. If I had I might not even written my mean post about Simplify3D as that feature alone is worth the price of admission!
