Tom, I use ngcgui and just fill in the blanks for length of cut. I have one called x-trim that I just need speed and length and off I go.
Before ngcgui I just used a file called x-trim.ngc and edited the X and F. x-trim.ngc G20 (Units: Inches) G40 (Cancel Cutter Comp) G90 (Absolute Mode) G64 P0.005 (Continuous mode + path tolerance) G92 X0 Y0 o<touchoff> call [0.100] [0] [0.08] (Touchoff and start cutting) F70 G1 X6 M5 (Torch Off) G0 Z0.500 X0.000 G92.1 (Cancel offsets and set to zero) G0 Z0 M2 touchoff.ngc o<touchoff> sub (#1 pierce height, #2 pierce delay, #3 cut height) F10 G38.2 Z-1.75 (Probe to find the surface) G91 G1 Z0.070 (Raise up to Z0) G90 G92 Z0 (Set Z0) G1 Z#1 M3 S1 M66 P0 L1 Q5 (Wait for Arc OK from Torch) G4 P#2 (Pause for pierce delay) F25 Z#3 (goto cut height) o<touchoff> endsub M2 John On 5/14/2012 10:24 PM, Tom Easterday wrote: > Is there a simple conversational way in Linuxcnc (2.5) to cut a straight line > or a simple pattern?
