  • You have a draft going through your room, I used to have same issue when my printer was beside a window. Less when I moved the printer to middle of the room and issue was gone when put the printer into a closet. With closed doors.

    You can try lowering bed temperature to, the warm bed keeps lower layer pliable but the upper layers cool and contract pulling the more flexible layer up and away. So a cooler bed temp should make the bottom layers more ridgid.












  • What printer do you use. This is a mechanical issue. It’s something binding as the one x or y is traveling could be a bearing or the stepper motor it self. It prevents the arc from being fully formed even though the machine thinks it is key point you made is that randomized z seam leaves the same mess, but if notice it’s not all the layers are cut short only some.

    Take the belt off and move the axis by hand slow and easy do you feel anything that isn’t smooth like silk? That would be it. Feel the stepper is the drive gear tight any slip ?? Any play in the shaft side?

    Edit

    Looking at the pictures again I’d bet that if you went taller and printed faster, it would be even worse because the bad part got hotter and more bound up more Alternatively printing faster might make it better because you have the inertia to push past the binding spot.






  • Yeah i crashed it like 3 times already. Does that make me a seasoned veteran? Lucky me it cones with a cutout clutch that has saved , the work, machine and my pants.

    Right now It’s less so questions as more of I don’t know what I don’t know.

    Tool angles and geometry Is one, is carbide viable for one of these or should I be using high speed steel for boring?

    For speeds and feeds do you use the general rules as you would for turning or milling or something else?

    Work holding fixtures any recommendations on what is essential to have at the ready? Most used ?
