sheetcam thc300 post porcesssor help
« on: May 13, 2009, 08:29:51 PM »
hello all,

I am a newbie trying to learn the code of the thc300 post processor. I have drawn a simple square and applied the thc300 post processor to it.

I have been having issues with certain settings under sheet cam. My issues are as follows:

1. How do I set the speed of the z movement when the torch plunges for stock. I have changed the the plunge rate though the "plasma cutter properties page" with no success

2. How do I set the rapid speed of the z axis when the torch is motion.

attached is the .tap file that was created by sheetcam

N0000 (Filename: square5555.tap)

Also can someone explain certain functions within the posted g-code as i do not understand them.

N0050 F1 (not sure what this does )
N0060 S500 (not sure what this does )
N0100 G00 Z0.0000 (i assume this is the plunge, How do I change the g00 for a specific feed rate)

thanks for any help in advance
