I recently bought my first 3D printer. I ordered a Tronxy P802MA but got a DYMCO clone. After initial difficulties, I got it printing like a charm. Then about 2 days ago, it would not print anything that I sliced (cura engine in repetier) I had tried to install the skeinforge slicer just before that. I uninstalled everything and reinstalled Repetier but still no joy. Finally, I found a setting where I could set the firmware to repetier and got it printing again. Today, I tried to print and again no joy. I should mention that I have been printing from the sd card. I can still print things that I sliced earlier, but can’t print anything I slice now. When I try to print, the display shows it reading the sd card from 0% to 100% and then it stops with no printing. Any ideas would be appreciated.
