  1. Re: Laser control software alternative to BenBox?

    Benbox is pretty terrible, but look for T2Laser or a new program called BenCutLaser.

    There's a forum dedicated to these machines (you should be able to find by searching).

    Corel is the best option, and importing dxf's to Newlydraw works great.

    The amount you need to apply as a contour depends on the material, but i would suggest 0.02 - 0.04 mm as a starting point.

    The PSU may not be wired correctly, depending on your model the interlock and/or laser enable circuits need to be grounded or held at correct input.
