I’ve had super good success with this glass bed without using glue or hairspray. However, my latest print, after a bed leveling procedure, got a little blotchy and sort of screwed up the print. I’ve tried leveling a little tighter with no luck and a little loser. Not sure what could be causing this. Maybe an extruder cleaning is in order? I appreciate any comments that could help me get this ironed out. Thanks, Keith
