Cuttting holes...need Help!!!

Post by maher92 »

Hi everyone,
I need help with the hole cutting CNC plasma machine,when the machine starts the first processing very well
but when it goes the other flame does not go out on time and leaves traces on the surface,whether it is to machine settings or program(drawing) preparation???

CNC Machine: Kasry KR-PLD Multi-torch CNC cutting machine

Plasma Cutting system:Hypertherm MaxPro200

Perhaps posting some of your G code would help get a diagnosis.

Well, I am no expert at G code, but my post processor puts a half second pause after completing a cut and before moving on to allow the the plasma cutter time to react before moving (i.e. turn off). I don't see any pauses in your code. Perhaps others could chime in on their thoughts.
