Hello,
I've got one strange problem with cutting. It seems like mach3 periodically changes how the motor work. Sometimes pressing a direction arrow will make 3 motors move while other times everything is normal. It did it to me during a test cut (just retro fit a plasma). I wanted to make a 5" circle with a center hole. It did not move to the right spot to put the hole in, then it cut the outside of the circle as a half moon.
I'm adding the gcode as txt file and sending a picture of what it made.
