    Starting out with just pen drawings at the moment but

    My Z axis is skipping every so often in the upward direction? i’m wondering if it’s because its trying to raise too quickly causing it to skip?

    where can I specify the maximum up speed for the z axis in Estl cam? I have the speed set for 1.5mm for the down but don’t see anywhere for the up?

    thanks for the help

    F(z) is you speed up and down. Make sure the threaded rod is straight, and lubed. Run it up and down by hand to see if you can feel any spots that are dragging, might even be a spot on the rod that has messed up threads. I had that, just flipped the rod.

    Thanks Barry,

    I’ll try pulling it out tonight, lubricated and searching for any tough spots
