hey everyone. Got a unit, pretty much rebuilt it from the point where the bed wasnt working. If a uv printer fb3328, this thing is pretty cool, just getting general error. Looked up the back end and thus far just rebuilt the head, jesus... that was horrible... now im trying to figure out why my sensors are acting up. We flushed the ink, two reds dots in the front one under ink, other says error. No manual and yes I know china sucks. lol
