I thought I'd share a print failure that was caused by an issue that I haven't read or seen here before.
The object is a 1/72 scale fuel discharge nozzle (i.e. a "gas pump handle"). I added the supports manually using B9 Creator and then sliced it using ChTuBox.
However, it totally failed to print. I was baffled because all of the other objects included in the job were successful, but I could tell as soon as the print started that something was wrong with this specific object. The printer screen showed all of the other base layers printing, but not this one. This object only showed up once the Z-axis had reached about .5mm.
Anyways, the fault was a small artifact sticking out of the bottom of the raft. This was a cresent, about .3mm thick, that was part of one of the supports.
When I put the object in ChiTuBox, the slicer did actually put it on the work surface, but all that was touching was this microscopic artifact. This meant that the base layers were never actually printed on the bottom of the bed, and the rest of the object failed to print.
On the next print setup I added the nozzle again and almost didn't catch the problem until I checked the slices one last time and noticed that at zero on the Z-axis there was nothing. It was then that I checked the setup from the bottom and saw the little artifact holding the rest of the .stl off the work surface.
The solution was to simply lower the Z-axis by about .4 mm. A successful print this time.
Anyways, lesson learned is to always check that the objects really are sitting fully on the work surface.
