I have a BLV printer with DUET (Reprap firmware), latest Simplify3D software.
Most importent problem: when I start a print the position of the printerhead is not correct, it's almost outside the printerbed!
When I load an STL-file (size=200x200) for my Ultimaker3, I can print it: no issues.
When I select the BLV printer (which has a bigger bed: 345x350), this is not shown in the Simplify3D software: the bed is not resized (you expect that), ofcourse using the same STL file.
Seems to be the software needs some improvements..
