Stepper motors are (typically) open-loop, but the motion control logic in Machinekit and LCNC are closed-loop. That many joint following errors probably means you either have problems with your HAL file (typically a goof in how the position command and position feedback signals are connected) or there's some other basic problem (eg: your scale is far enough out of wack that it's impossible for the stepgen instances to keep up with the commanded positions).
Post your INI & HAL file and we can review. It looks like there's a link to your HAL file, but Google is being weird and I can't open it. Also, we'd typically need to see your INI file as well unless you aren't pulling any ini values into your HAL file.
