Ah I don't think I have a PTFE tube with my printer, could be that causing it?

Everything seems to be working more or less perfectly now, but my extruder stops working about 20 mins into any print. Is this a common problem? How do I fix it?

This was PLA at 200 degrees, which seems to work for a while.

I've looked here but it's not really ...

I was flashing firmware because my printers (Prusa I3 Pro B) Y axis was working in reverse, and it encountered an "unknown error". Now I'm worried that I have broken the board forever.

Is there any way to factory reset the board? I'm trying some things with the Arduino software with little success ...
