This would apply to anyone with a similar laser with a small working area. The Mr Carve M1 and M1 Pro state a 70mm square working area and burn size. The lens on my M1 Pro is a 100 though and that seems to equate somewhat to the maximum area that can be used.
Somewhere I mention that I can't see how a different lens can affect the laser power.
with a change of focal length comes a change is laser dot size, that is where the reduction in power comes from, a larger dot means less power...
