I have a Milltronics Partner 1G Centurion V

I power up the machine and when trying to Home Machine it moves X axis erratic and Z drifts down till error 449 or 409,

I put together a webpage to display pictures of the machine and a video of the problem, thanks in advance for your help.

here is the link to my Milltronics Page http://ohton.com/449.htm
