You have come a long way with your mill! Nice to see. It would work better if you would change the way you have the carriage cable attached on the drum. The cable ends should be attached to the Carriage. Take the middle of your cable length and make about 4 wraps around the drum. Then place a turn buckle at one of the cable ends that attach to the carriage. This will allow you to take up slack in the cable and not have all that back and forth jerking of the carriage.
