Print Aborted

Running out of filament

The amount of initial filiament shipped with my Geeetech_A10 was simply not enough to finish the print job:

Rebooting computer while USB is connected

When installing a new USB driver the computer rebooted - it's probably the same if you unplug and plug the USB cable while printing from SD card:

Speed

Experiments with a small test cube

Print accurary in mmm

1. 0.6 mm - 5 min
2. 0.4 mm - 7 min
3. 0.3 mm - 9:27 min
4. 0.2 mm - 12:26 min

In the design i printed the accuracy and temperature as text so that the samples will "document themselves ..."
