Loading the part up in blender, translating it by the X Y Z indicated in Repetier host, and then putting the 3d cursor at the specified coordinates:
Nothing suspcious? Rereading: it said “near edge”, so there should be an edge between those two locations. Because the X and Z stay constant, its along the Y axis. So it must be one of these guys:
Aha – I think I found it. There’s actually several vertices here. Ctrl-+ a few times to grow selection, Shift H to hide unselected, and then move some stuff around.
Delete the vertex, look for holes and fix:
Send it back over to slicer, and try again:
Not winning today.
Update: didn’t seem to have any problems with slic3r 1.01. Now I have to figure out how to configure Repetier Host to talk to a new slic3r install on the computer. (Update: very easy. Tell RH which directory slic3r lives in, and it handles the rest).
