Can you zero the left side of the table with an edge finder?

Is there enough travel room to zero the left edge of the x axis with an edge finder?

I thought there was but then I lined up my piece of stock on with the left edge of the wasteboard/plate and I can’t seem to go far enough to the left with the spindle. I thought I had done it before but now I can’t and I’m not sure if my memory is just wrong. The grease on the support rails makes it look like it’s stopping ~0.25" further to the right than it had previously. Am I crazy?
