I got a pp50 with my plasma table. Since day one the torch will turn on with gcode M03 but when it should shut off at gcode M05 it's still firing when the gantry moves to the next cut and ruining the metal. I am using draftsight to draw, sheetcam to process and mach 3 to run the table. My table has stepper motors with a gecko 540 driver and proma thc.
My system does not have water in the lines, my pressure is set to 70 psi. I have new consumables on it. When I check the gcode it's all there but the torch will not shut off untill it moves across the steel to the second cut, then the torch shuts off and and the gantry continues to move as though the torch is cutting the second cut. Once it does this it moves to the third cut starts normally and at the end of that cut does the same thing, moves across the metal with the torch on and then shuts off with the machine still moving as though its cutting. This is repeated until the the gcode cycle completes the run. Any help would be greatly appreciated.
