Hey guys. I have a flashforge creator pro. I have successfully printed objects with it before. Then it got clogged. Before I knew what I was doing, I tried unclogging the nozzles with a pin. Now that I have properly unclogged my extruders by disassembling them, I can’t get my prints to stay down. The plastic just doesn’t go flat on the build platform anymore. Have I accidentally hollowed out the inner diameter of my nozzles? I have not been able to print anything for weeks. http://ift.tt/29CRtgo
