No, I was actually working with an OEM who sold a sign software package that generated Gcode (very expensive). The problem was that their software generated way too many short segments for no good reason which caused problems on the machine controls (it wasn't LinuxCNC or Mach3). They simply refused to alter their code saying that the machine control "should" be able to handle as many short segments as they want to throw at it and still run at high speeds.
The machine control choked badly (no surprise) and was running 10 or 15% of the desired speed. In the end, I don't think that anything was ever fixed. And the machines still run slowly. I later learned that this is a common stance in the art industry. They expect the machine controller to handle whatever garbage they throw at it. Artists and some of the people associated with artists tend to live in different realm, reality, or dimension. ;-) Logic is oftentimes discarded!
