请假大师们,刚买的胜家5523,用不同面料试机子,发现不像胜家使用视频上说的那么好,不论薄料厚料面线压力怎么调都会看到底线露出来,后来调紧了下底线张力,厚布料好些了,露出一点点,可是薄料还是不行,卖家也不懂机器,说是正常的,说他用4423走窗帘布也是针角看的到底线,我就纳闷了,这一千多的机器,视频里也是实实在在看到线迹走得很好,为什么到我手上遇到面线压力问题就变成正常的了?买了胜家的朋友们也遇到这种问题吗?卖家最后还说这不是个例,是胜家机器都有这个问题,真是这样吗?
再则,机器退货很麻烦,我也想要是有大师能帮忙教下怎么调节,问题解决了我也不想麻烦得去退货了,先拜谢了![](http://static.tieba.baidu.com/tb/editor/images/client/image_emoticon36.png)
