Rounded corners on vertical axis
Related to print quality issues mentioned here, I've noticed that models that should have nice clean sharp corners are quite rounded, almost as if the linear acc is rounding the edges to make the print job faster.
For example, when I print these two parts with the flat side on the bed, the result is a nice seamless fit when I put the two together. But if I print upright on X or Y orientation, putting the two together really shows that rounded corner that should be nice and sharp.
I'm thinking about trying this without linear acceleration to see if that's the culprit, is there an easy way to disable it in Slic3r?
Re: Rounded corners on vertical axis
comment out or remove the M900 line in the gcode
probably filament custom gcode section,
maybe something like this !
; M900 K{if printer_notes=~/.*PRINTER_HAS_BOWDEN.*/}200{else}30{endif}; Filament gcode
you may need to increase the retraction setting a little to compensate

Keep in mind that corners in the XY plane will always be rounded, with a radius at least equal to half the extrusion width. This is inherent to FDM printing.
If you want to join parts with no visible seam, you have to either print the parts with the join surface as the top or bottom (the only way to get a perfectly square corner), or design the part so the seam is concealed somehow.
