I have been using a GCC LaserPro X252 cutter now for about 6 months almost continuously. But today when cutting some balsa parts for a model, it decided to go so slow around a curve it set fire to the material. This has never happened at all before, it generally doesn't slow down that much for curves and this particular part has been cut several times before without incident.

I have since put in and cut a different part which I know not to do this, and the same thing happened on that.

Any ideas as to what is going on? Have I accidently altered a setting somewhere? has the software become corrupt? I have been through the driver intereface several times now and can see nothing different to what has been used before, please help if you can
