[sudo-discuss] laser cutter limit switch broken

[hol at gaskill.com]

 yep that's what I was doing - based on this and Jake's comment it may
just be something to work around. I was burning a small raster job (used
ms paint for some text for lack of time) saturday afternoon and the
first few scan lines printed fine, then repeated craziness of banging
against the wall.

Not sure next time I'll make it over but here is a decent vector drawing
of the sudo logo that someone could make into a stencil with ease. very
small pieces hold it together so be careful with the power setting!
