I’ve started messing with 2 sided machining and I’ve run into a reproducible problem. every STL file I try to do a 2 sided op on ends up being off by 2mm in the Y axis regardless of how large or complex the file. I have found similar reports here https://discuss.inventables.com/t/meshcam-issue-with-2-sided-milling/22780 and here https://discuss.inventables.com/t/2-sided-or-1-sided/22884 but no resolutions. My process is
Import STL and select 2 sided machining
define my stock and be sure to select center X,Y and Z
create my supports
set program zero to be the mid line of the model
generate toolpaths.
I have a Shapeoko 3 with the threaded table, so I drill two holes on a center line and bolt my stock to the table and only flip in the Y direction. I’ve emailed grz for support to see if they know of anything but thought I would reach out to the forums too. Anyone else run into this sort of problem?
