Please watch the video and give me your thoughts... I noticed this yesterday. The top black plate on the carriage has slop in it. Surely this is not normal... I just happened to see the movement and decided to see how much play was in it with the dial indicator... The play is in the 2 supports for carriage that the cross slide rests on....
