And other part is extruder, A6 combines A8 and Industrial 3D Printer. The extruder feature decide A6 with a better precision. The difference between Auto level A6/A8 and Normal A6/A8: 1. Auto level A6/A8 work with LCD2004, the firmware are not the same from Normal A6 . 2.Auto-leveling uses a proximity sensor to detect the aluminum print bed where the normal version of the printer uses a micro-switch to detect the end of travel for the Z-Axis movement (vertical limits).
