A couple reasons that the equity financing (LOC) has not been tapped:

1. It was designed for higher share prices. At high prices, it has a reasonable cost. At low share prices, the discount becomes too great percentagewise and better financing is available.

2. Also, the amount per month is limited by both the maximum amount of money (in case the share rice is much higher), and by the number of shares per month. At the present prices, the amount of money that could be accessed per month even using the maximum number of shares is quite low (probably around $50k), and therefore simply not worth it- especially if it costs more than alternative financing. And remember, SFMI has a number of options. As BOUTS said, the equity financing is a backup, not the first choice.
