about 1. Have you calibrated the steps/mm of each carriage? I usually calibrate it by measuring how much the carriage is lowered with a digital caliper with the effector as close as possible to each tower. Close to a tower, z movement error is due to that tower's carriage movement error, errors on other carriage movements create x and y errors, but not z errors.
