To all those who have used, or still use Mach3, you might be interested to know that Art Fenerty, the programmer of Mach3, has now retired.
He has played a major part in turning the CNC world upside down and making CNC affordable to the masses.
He has handed over the reigns to Brian Barker, who is continuing to build on top of Arts code.
If you wanted to wish him well, you could post in this thread, and I will get him to check here from time to time.
