    Z axis freezes

    in Improve your 3D prints

    Posted

    Hello
    I have performed several checks including the gcode (thanks gr5)
    I didn't find anything strange and the printing was blocked on the Z axis at the end of the support (6.9mm for my part)
    Finally I started again from the basic PLA Fine setting on CURA and is modified some parameters (temp, wall etc) and now everything works.

    This is all weird.
    Greetings

    hello
    I use an anet A8 with the original firmware and CURA since version 3.5.

    Since version 3.6 I have some problems:
    On some parts the Z axis freezes.
    For example my last print which is a total of 17mm high with supports, the printing starts and works very well up to 7.9mm then the Z axis remains locked at this value, but the printing of the layers does not stop. This damages the print head.


    I tried to regenerate the gcode: idem
    Other printing can be done without any problem
     

    Of course I checked the functioning of the Z axis in manual mode and there is no problem.

    Does anyone have any idea
