I'm currently nearing the end of a 2 day, close to full height build on an UM3 and the prime tower finally decided to give way after looking pretty shaky for the last 8 hours or so. I've got about an hour left of pulling filament out of the nozzle at the end of each "ghost" layer of the prime tower as to hopefully let the build finish successfully.
Anyway, the prime tower was already 20mm in size and I dont really have any desire to go up any further if I dont have to. So instead of enlarging the cross section, is there a way to change the prime tower geometry? For instance is there a way to change the Gcode to print a hollow square tube with wall thickness x that is 30mm or 40 mm instead of a solid square pillar? I have no familiarity with gcode so I have no idea.
Thanks!
