I'm using the beckdac firmware on my i3v 10" and the first print off the sd card always ignores the ABL routine. What gives!?

Also, what can I do to make the ABL mechanism more robust? The TowerPro servo seems to get out of whack often and I can't stand the fact that I can't just hit print and feel confident ABL will "just work". Am I the only one experiencing this? Is there a better servo to get? Is there a better alternative available? I've seen BLTouch https://www.indiegogo.com/projects/b...-3d-printers#/ .

Thanks a bunch,
Matt
