    Seem to have developed a "grunch" noise and loss of steps in -Y direction.

    Printer had not been used in some months.

    Wondering where in firmware I might look to tinker with acceleration/ramp up/down rates?

    For instance in configuration.h I find these, but do not think I fully grasp what they do.

    #define DEFAULT_MAX_FEEDRATE {500, 500, 5, 25} // (mm/sec)
    #define DEFAULT_MAX_ACCELERATION {9000,9000,100,10000} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for Skeinforge 40+, for older versions raise them a lot.

    #define DEFAULT_ACCELERATION 1300 // X, Y, Z and E max acceleration in mm/s^2 for printing moves /robo
    #define DEFAULT_RETRACT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for retracts
    . . .
    // The speed change that does not require acceleration (i.e. the software might assume it can be done instantaneously)
    #define DEFAULT_XYJERK 17.0 // (mm/sec)
    #define DEFAULT_ZJERK 0.4 // (mm/sec)
    #define DEFAULT_EJERK 5.0 // (mm/sec)


    Thanks.

    After a bit of browsing, I changed #define DEFAULT_XYJERK to 12 and recompiled.

    After "upload" it tells me upload complete, but I did not see any indication on the Robo LCD that anything happened. Should I? How can I tell if it uploaded the new values?

    Never mind, I enabled "Terminal mode" and it tells me it uploaded today, a few minutes ago.
