This printer used to print great, but it wasn't used for a while. Now it won't print anything without bunching up on the first layer.
I've tried calibrating the Z-offset, but it didn't seem to help. I've also tried many different temperature variations. The issues seems to be the nozzle catching a line as it is moving or it could just not be sticking to the bed. I'm not entirely sure. It's hard to tell. Sometimes it will make it a decent way into the first layer before messing up.
I need help
