I have wanhao duplicator 6 which I try to use S3D to generate GCode for.
However, I show the error that relate to "Printing Area". After some experiment, the problem came up that the printer doesn't support any negative distance or extrusion length value.
I'm also not successful to use relative mode in both Z leveling and Extrusion Distance. The z distance could be fixed with the changing in initial script but the negative extrusion still remain.
With retraction, the first layer has some negative E-distance value from retraction. Therefore is it possible to OFFSET the E-distance (by wasting some filament to gain some offset at the initial printing) ?
