Won't use the full platform

Lately I’ve been having this problem that I can’t print on the left side of the platform, as you see on the picture it just cuts off. It’s like it can’t move further left but if I manually move it in Repetier host it works just fine.
Anyone know what could be causing this?

This maybe due to the offset of the print head.

It’s indeed normal. On the object placement view there’s a black dot on the bed. You can’t place anything to the left or in front of the dot.

Ahh! thank you, I always figured the black dot was the extruder in it’s home position. ( Yes, even though it’s on the wrong side, figured the program was mistaken. )
