  • Klipper配置远程+近程双挤出机

    • 两个挤出机,一个再近程,一个再远程
    • 此办法可以混合实用挤出机,比如近程bmg远程M4
    • 我想要这么搞的原因是,这样对近程挤出机要求很低,提供一点压力,就可以非常顺的打印。 远程会释放近程挤出机的压力
    • 此方式需要调整挤出机压紧轮的压力,因为压力会影响到挤出机的挤出长度,除非用供料管,不然两个挤出机之间的长度会有变化

    ##  Update value below when you perform extruder calibration
    ##  If you ask for 100mm of filament, but in reality it is 98mm:
    ##  rotation_distance = <previous_rotation_distance> * <actual_extrude_distance> / 100
    ##  22.6789511 is a good starting point
    rotation_distance: 25.12    #bmg 
    ##  Update Gear Ratio depending on your Extruder Type
    ##  Use 50:17 for Afterburner/Clockwork (BMG Gear Ratio)
    ##  Use 80:20 for M4, M3.1

    要是不同挤出机不同电机,还得慢慢调一样的挤出长度,用一模一样的挤出机和电机的话设置调一样的,驱动位不够的主板直接一分二,电流调双倍就可以了吧,大佬。

    先要把两个挤出机,的步进值微调到一致吧。

    想明白了,两个挤出机,一个在近端,一个在远端,同时发力?这个要求电机和挤出机都一样才更好吧,配置,电流都要一样。
