This is a torture test for DualStrusion accuracy - drawing lines of alternating colours from 0.5mm to 4mm in 0.5mm increments.There seems to be a slight overlap of lines at 0.5mm, but just barely.1) Open AccuracyTest.gcode in ReplicatorG and print.If you want to play with the components, the OpenSCAD script is included, as are the individual STL files that I merged to create the gCode file. For some reason, ReplicatorG is unable to open the STL that it merged from the individual layers.
