Repost from A10 Board - A10 Messed Up

So my printer worked perfectly with the test print 3/4 of the way and turned to spaghetti. But I'm going to guess that was a simple problem with temperature.

The real problem is when I tried printing a second, third, fourth, and fifth time on it. The printer would print off the bed at the nozzle's home, it would scrape the bed with the nozzle when it did go on (which hurt to see every time I tried to fix the printing off the bed issue), and this clogged the nozzle- I have no idea how to get it off. I'm really disappointed, because I've tried to reset the home position, change the file type, etc. But nothing has worked. I don't want to keep experimenting with solutions because I'm worried I'll mess up the bed, and on top of that the nozzle is clogged so it wouldn't print anyway. I have tried to twist it off while heated but the plastic (or something) held it on and it just ended up stripping the tool.
