What is happening is when i am printing multiple pieces on the bed, The left nozzle is hitting some of the prints on the bed when the print head moves on the x over certain portions of the bed. My best guess is that this is caused by the adjustment being made by MBL? BBv1.1 Dual Hybrid Titan IR Sensor moves to the z frame I have already done the following... I have disassembled and reassembled the hot ends. re fit them in the print carriage according to the build manual. I have adjusted the z of each nozzle using your alignment tool in the center of the bed. The z frame and and glass have been mechanically leveled. Mesh bed level and stored to memory. Any ideas? Any help would be greatly appreciated.
