It seems that the first layer height is also affecting it, but no the way I expected.\r\nSetting first layer width back to the same as the other layers had little effect, the other layers were still going half the speed they should have. Setting the first layer height though to the same as the other layers height the speeds now went back to the expected speed (about twice as fast).\r\n\r\nI had first layer height set to 0.2 and subsequent layers set to 0.5. setting first layer height to 0.5 fixed the speeds. Unfortunately I need to be able to set the first layer width and height differently to the other layers to get decent adhesion.\r\n\r\nI'm not sure there is enough information here to debug the issue, so let me know more you need :)"}}
