For the accuracy/backlash test, I suggest that people report the measured length of the diameter in the X direction and the Y direction so that there will be a clear picture of where different people's results differ.<div><br></div><div>Please remember to list:</div><div>1. Filament source</div><div>2. Print time since slower printing may increase the quality of a print</div><div>3. Software settings used such as layer height, nozzle temperature and quality mode.</div>

<p>@Cymon overhang tests are highly dependent on layer height. As long as your print head isn't too hot, you mostly just have to make sure your next layer will overlap at least 50% with the layer below it. e.g. with 0.1 mm layer height an 0.4 mm line width, you can print up to 26 degrees reasonable well. At 0.15 mm layer height, the limit is more like 36 degrees. So, if you want to push the machine to failure, just make your layers thicker.</p><p>Of course, nozzle geometry also plays some roll, but the aforementioned has been my general experience. I would also admit that at some point, the layer below would be to thin to support plastic being extruded on to it or absorb the heat of the extruded plastic without melting, but I think that is more of a material limitation than a limitation of the machine.</p>

I don't like that the overhang stops at 70 degrees. Why stop before you know it will fail. Go for failure and see who survives.
