Strange issue with fine resolution prints
I have a Flash Forge printer utilizing Makerware. I use both PLA and ABS in the 1.75 mm size. It's been a great experience so far, but I've noted one minor issue that crops up at times. Since I use my prints for metal casting, I often want them printed in the highest detail possible, which would be .10 mm on my printer. Occasionally, however, the printer simply can't or won't print a model at .10 mm. It'll get about 5 minutes in to the print and then start spraying a random ball of filament all over the place. At first I thought it was a platform leveling issue, but multiple attempts at leveling and calibrating the nozzle did nothing. By chance, I discovered that if I set my print resolution to .20 mm or higher on these "problem" prints, the model prints perfectly. I seem to have solved the problem, but I'm wondering if anyone knows what is causing this and how to avoid it? As I said, it's only certain models that cause this, and I'm at a loss to figure out what common factor they all may have. It also happens with both ABS and PLA.
