    i switched the z-axis to motor 4 on the tinyg board and configured it as i had motor 3 before. no problems. runs like a champ now. i now guess it’s something electrical with the tinyg board rather than software/mechanical??

    Thanks, Alden!

    I tried your settings, but the problem persists. I even loosened the coupler to the leadscrew and it still happens.

    Hey Folks,

    Thanks for your responses thus far…

    I recently updated to the new firmware master, and I’ve been tweaking the machine for no-load speeds for some special applications. My velocity, jerk and feedrates are higher than if I were using a tool to cut. I’ve verified these setting work reliably when entering single commands or sending simple programs via CoolTerm.

    I do have XON enabled:

    If I send a simple program like this:

    G21

    G90

    G0Z75.00

    Z0.00

    G1Z75.00F1000

    Z0.00

    M30

     

    This is the result:

    But if I send something more complicated:

    This is what I get:

    You can hear the buzzing when the z-axis stalls.

    I guess the big question is this: Why do I not have problems with the first program, but I do with the second?

    By the way, the code was generated with RhinoV4+RhinoCAM using a post customized for the ShapeOko.

    Thanks again…
