Image Modified	First Layer Adhesion - poor adhesion on your first layer, characterized by blobs of hot plastic and cursing	See 3D Printing Material - FDM for the ideal bed surface for your filament. (re)Apply hair spray or glue stick Increase the height of your first layer only Add structure to your print to enhance adhesion, such as brim Check the nozzle clearance when homed on the z-axis. Most printers should be between 0.006 and 0.010 inches.	Please request assistance if the printer must be adjusted.
