Hi @shahramrobotics I can totally understand the Photoshop analogy, however, that raises other questions (for me!) when looking at the image from @alexrp92. If we have a square at 250x250 and a spot that’s 140 in diameter, it seems to me that it should be impossible to get good corners for that square. See attached first pic. The spot could get no closer to the corners than shown, so the filled square should look something like the orange area of the second pic (assuming the “circle” is able to be positioned to 10 microns multiple times within the square). However, Alex’s image shows quite sharp corners on the left-hand side, they’re not pin-sharp, but they look a lot more “square” than fitting a 140 micron circle into a 250 micron square suggests should be possible.
Not sure what slicing software you’re using, but Preform (for Formlabs) does not remove details at this level (see final image). This is a quick mock up of Alex’s model, the cubes are 250 microns, the support touch point 300 microns.
Not really arguing here - I’d certainly agree you can’t fit a circular peg perfectly into a square hole - I’m more just interested in the tech/processes!
