It should be able to accelerate a lot faster along X than Y. So raster engraves should be OK but cuts and scores along the Y axis might be a problem. It might have to take a run at it. So instead of slowing to take a corner it would turn off the beam, overshoot and then come back at speed in another direction and turn the beam on where it crosses where it turned it off. That would reduce the work area though.
Pure conjecture as never any official info of problems but if it is in the hopper then it must not be straight forward.
