Cuttting holes...need Help!!!

[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

Nesting Software: FastCAM

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.

Have you tried putting a lead out? This solved quite a few issues for me on holes
