Hi Andy, Well done mate it's coming along nicely. Have you checked the steps per is correct because It doesn't look like it's traveling 8 or 10mtr/min to me, thou it's hard to tell from a video? Just use MDI and tell it to move a distance and check it moved the commanded distance. ie: G0 X100 it should move 100mm. Make sure you Zero the axis first and leave enough space to travel.
