Precision of Joint Movement
I’m in the start-up phase of the AR4 right now. When I jog a joint by 10°, I measure about 10° ± 0.5°. Is that normal, or could there be an issue?
When I jog in Cartesian coordinates along the Z-axis, the gripper doesn’t stay level but tilts by about 8° over the full travel distance. Could this be related to the problem I mentioned above, or could it be that the coordinate system referenced is rotated?
It should calibrate to 10 degrees unless there is a belt tension issues or something like that. How are you measuring the J1 angle? Can you send me a video jogging in the Z axis info@anninrobotics.com This is typically caused by a calibration issue but I would like to see the movement.
