    so I’m at a loss, since a couple of weeks I’m trying to get my tinyg working with on of my xcarves and no matter what I do, it always moves way to far.

    For example I tell it to to X1 in metric mode, but it seems to be always moving in inches, so it moves to 1″. If I switch to inch mode and tell it to go to X1, it seems to move > 10 inches, which is really odd.

    Anybody has any idea what the cause for this could be?

    I reset it to factory settings, etc. The only thing I haven’t done yet is update the firmware.

    thanks and kind regards,

    Gert

    You do need to update your FW, but 440.14 should not be behaving like this.

    >>> If you are, perchance, using tgFX, stop here.
    tgFX is no longer supported.
    We’ll have a whole different discussion on how to proceed.

    What do you use as a GUI interface (Chilipeppr, CoolTerm, ….)?
    You say you reset to factory defaults, then obviously tweaked some, but not all of your parameters.
    How did you make parameter changes? ChiliPeppr CLI, ChiliPeppr configuretinyG widget, CoolTerm,… ?

    What you posted is a somewhat unusual configuration.
    You have the Z axis set to $3tr=40mm, same as X and Y.
    You have $_mi=1, no microstepping on X,Y, and Z.
    Your motors are assigned to X,Y,Z and A.
    I believe XCarve has two Y motors, you have them both connected to a single driver (motor 2 driver)?

    What setup guidelines are you following?

    Regarding your feedback I use coolterm, as well as a custom software I developed. But lets just sick with coolterm.

    I will attempt to update the firmware later tonight, to see if this solves these issues.

    regarding my posted configuration, it might be a bit unusual, but let’s focus just on the X and Y axis, which should behave like any normal xcarve/shapeoko 2. We just use this platform as foundation for developing a different robot.

    The setup is also based on the standard shapeokoe configuration pages and the settings should reflect this (again only for the x and y axis. ignore the z).

    This still sadly does not explain, why both the inch as well as the metric modes are so far off.

    ok after updating the firmware, it ended up working as supposed.

    OK, good news for you.

    It is difficult to predict the root of your original problem.
    We see, occasionally, corruption of internal constants and parameters that get cleared (reset) with a FW upgrade or when a $defa=1 command gets executed.

    I recommend that you frequently keeps backups of your $$ parameter sets.

    Also, exercise caution when coding custom software that downloads parameters to tinyG. It is best to send parameters one at a time, waiting for a tinyG acknowledgement before proceeding.

    Good luck with your project
