I own a Redsail RS3040, but I'm not happy with the machine when cutting. Since it has different resulution on X and Y direction (1000 vs 2000) it cuts much deeper in one direction. And since the included software isnt that good I have been thinking about rebuild the machine using 2 step motor drivers (routoutcnc has a kit for £88 with to step motor drivers and a break out card) and use the LinkMotions software (expensive :( ) to drive it.

Before I start I wounder if anyone has any experience of LinkMotions for CO2 lasers?
Does anyone know about some "cheaper" alternative to LinkMotion (which adjust the power of the laser depending on X-Y speed)

Does anyone know how the power of the laser is controlled in the RS3040? Is it by PWM(?) pulses?The max. power can be adjusted using a potentiometer at the laser unit, and than the power used when doing raster work can be adjusted in the Easy cut software.

Any thing else to think about?

Hi, we have the 3040 with the pot in stock I will take a look what do you want me to look at specifically then i will photo one for you
Thanks Chris
