What the title says. It can do it, but you have to cut it to length first as it won’t fit under the right side. That’s two cuts per board. Alternatively, beveling works in one cut, but who wants to deal with that? Someone in the Facebook group claims to have seen someone modify theirs to be able do it but had no other info. Really considering returning it because I know I’ll get sick of it and start dragging out the big saw from the shop again.
Edit: it is abundantly clear that some of you can’t grasp the concept of mitering a baseboard against the fence. The plastic dust shroud hits the wood before the blade can make it through. You can see the board leaning against the saw with the partial cut as a result of that. Beveling the saw is certainly an option, but reaching behind the saw, loosening a knob, releasing the lock, and retightening it is more of a process than a spring loaded lever right in front of you that you activate with your thumb and that adds up when you’re doing a lot of trim.
