Flsun 3D Printer / High Precision / Large printing size 260*260*350mm / 3d-Printer Kit / Hot Bed / One Roll Filament / Sd Card
The printer works great after assembly. Defaults in firmware are correct for motor directions so check motor and limit switches are connected correctly, paired if issues. Need to load Arduino to a PC, adjust extruder steps. Use repetier host and make a mark on filament by extruder motor, drive back 100mm in repetier (manual, extruder axis) and measure. Divide this number in mm by 100(expected) and in Marlin configuration file, search on "steps" and find the extruder steps parameter. Multiply it by your above result and amend the file. Be sure to also calculate autolevel z probe sense offset and load to Marlin, fix Marlin probe_bed_position back and right values (250 recommended) Download. Run home then G29 command to autolevel again, it should spread over more of the board's span.
