I found the problem. Stupid user error... I've been battling with this past 3 months.....
M671 X:-150:-150:800:800 Y-10:850:850:-10 S1
I have a : in front of the x axis coordinate X:-150
Ugh...
But Thank you very much guys administrator and Phaedrux wouldn't have been able to figure this one out without you guys.
