Well, my first 10mm or so is printing great. Very smooth. But then the stupid thing clogs after say 45 min of printing or so. This has happened on the last two prints back to back. I'm using grey PLA from MakerBot. I've done the auto tune PID tuning and everything was setup fine as far as I could tell. The clog is happening at the lower end of the connector between the heat block and the heat sink of the E3D. My Cura specs and a pic of my E3D install is attached. After the first clog, I was able to the plastic out only after disassembling the entire hotend and manually heating up the connector and pushing the clogged PLA out of it with a micro screwdriver. After I reassembled everything, I ran some hotend cleaner through it and it came out fine. Then I started printing again and the first layers were very nice. After about 45 min of printing, same crap again - the stupid thing clogged. Sorry, but the frustration level is getting high on this one. ANY feedback greatly appreciated.
