Thank you so much for breaking it down. I was about to pull my hair out. Right off the bat, I can see my first mistake...I was using a business card to level the table; I'll work on getting it better leveled. In my opinion, having three points to level is harder than four. I say that because when I try to level the back of the bed, sometimes one extruder is looser and the other tighter. I guess I'll just keep trying till I get it right. Thank you again Geoff, as always you're a major help.
