    I have the Problem that my hemera get extrem underextrusion after few layers and then after 1-2 h its blocking, seams the heatbreak did not work well...
    I upgrade the Fan with a 40x40x20 sunon fan ä with 13m³/h but it did not help.
    I only have a retraction of 1mm . Any ideas?

    I think nearly all fan "upgrades" are underpowered because they cant deliver the required static pressure. Try using the stock fan.
