LulzBot TAZ 6
Default slicing settings.
To preview one layer at a time both sliders need to be moved separately. I would prefer that when the sliders are together that moving the bottom (left) slicer up also pushed the top (right) slider up and moving the top (right) slider down would push the bottom slider down.
Alternatively, add a “+” and a “-” button that moved both sliders and maintained their relationship (i.e. if left slider is on layer 1 and the right slicer is on layer 5, the “+” button would move them to 2 and 6).
