Hi - I'm trying to print a light pipe using t-glase. Is there a way to make it print parallel lines including the infill? Also what combination of settings will generate a large diameter extrusion (similar to the raft) ? I've experimented with setting the nozzle diameter to 1mm with a layer height of .8mm and a print speed of 600mm/min. which works ok except for the infill problem. Suggestions would be appreciated.
