I would like to have LinuxCNC run a program from multiple different machine programs. We have Fadal, Haas, Fanuc and Simmens conrtols on differnt machines. It would be a great help if I can create a filter/replace file to help with this.

I am still learning all of this so please dont attack me out of the gate. Will this work?

#This is my filter section in .ini
# [FILTER]
# PROGRAM_EXTENSION = .png,.gif,.jpg Greyscale Depth Image
# PROGRAM_EXTENSION = .py Python Script
# png = image-to-gcode
# gif = image-to-gcode
# jpg = image-to-gcode
# py = python
# gcode = gcode-convert

#A typical Fadal line
# N33G00G90G40M01E01
#will be changed to
# N33G00G90G40M01G54
#replace "E01" with "G54" on all lines

#This will change E01 to G54 on all lines.
#!/bin/bash
sed -e 's/\( E01\)\([0-1000000]*\)/ G54\2/' $1

Did you see my post for a script to add a W axis to G code. I'd think you could use a similar program. I don't know anything about sed...

Thanks, Jon

Could this be made to run in the background while a machine is running a program? Ultimate goal would be for this to run while a program is being run.

I think you will find that the filter runs so fast that there is no point. Effectively you feed Axis one program, and a filtered one gets run.

Andy,

Just so I am clear. I load a program into axis or what ever GUI. The program that will run will be the filtered one? Or do I need to run the filter outside and then load the filtered program?

The Gcode will be automatically filtered and sent to the GUI.

Technically the filter runs and sends it's output to AXIS or Gscreen.

Yes.

As an example, try running the sim/axis configuration in the sample configs then open an image file (jpg, png) instead of a G-code file. You will see that you end up with G-code in the program window, not image data.
