    Printing Tips For Bowden Drive Printers

    Print Slower: 15 – 30 m/s
    First Layer Settings: 100% Height. 150% Width, 50% Speed
    Disable Retraction: Should reduce oozing and stringing

    Increase Multiplier: 1.1, should increase bonding

    Do not over extrude filament when loading. As soon as the filament start protruding from the nozzle, stop. Loading any faster will
    cause the filament to get caught in extruder gear.

    Feed the filament directly to the extruder, and not through the feeder tube. This reduces back tension in the filament as well as drag,
    ensuring proper feeding.
