Topic: Help, my robo was working great now its doing this!

Hey guys,

So my robo was doing great and then I must have dicked something up because now when it goes to extrude the first layer it just creates and drags around a glob of material. I included a video for ya because that much easier than explaining.

Its PLA plastic, Have tried bed temps 50 and 70, extruder 210. Have also tried hairspray, all to no avail.

From what I can tell, the nozzle is pushing into the bed instead of floating above it. I'm not sure how to stop the autobed leveling feature from doing this.
