My Marty doesn’t walk properly

When you’re calibrating your Marty, try to make sure it’s standing as shown in the photos (straight up, arms to the side, eyebrows flat) before clicking the “Save Calibration” button.

You have to save the calibration before you try walking. If it still doesn’t walk right, double check it’s put together correctly. In the calibration tool, make sure that the buttons move the appropriate joint - if they don’t, you might have plugged your motors in the wrong places.

Easily done and easily fixed - have a look at the electronics section of the build guide and make sure things are plugged in the correctly numbered port.

Check that the all the leg parts are oriented correctly, look at this diagram in the build guide and make sure your Marty’s legs look exactly like that
