A head scratcher for me

Here is ini file.
Currently, I cann't make screenshot of it.

If you open a terminal and
type
ls -l /home/user/linuxcnc/python
and then
Alt + PrtSc – Save a screenshot of the current window to Pictures
Then upload the screenshot

At photo there is filter.py (original) and filter2.py (edited for axes X,Y,Z,A), no one is run.

If you type ./filter2.py in the directory you have the filter in does it run?
It needs a g-code file as its input so if you type ./filter.py somefile.gcode
it should print out the altered g-code.

In the ini file the filter will work if it finds a g-code file with a .foam extension,

Give that a try

Hi Andy.
My machine use 3 AXIS, X,Y and A (rotate), how edit you module for use 3 axis ?

It only for 4 axis machines. Doesn't make any sense for 3 axis. You may be better looking at G93 Inverse Time Feed Mode

I don't remember if file run at that time, supposedly not. Possibly it was problem with python version.
But now, when I upgraded to Linux Buster and linux 2.8.1 it's run fine.
I will study this question more now

I maid some marks to Andys filter.py. I'm not a programmer and it's my first and earlier than "Hello world" python program.
I edited it for my needs. It's for colinear movement of Y and V axes. I also added A rotary axis.
Here is this file.


PS
This program doesn't solved my problem of slow motion when V axis is used.

Tried to add too with an error.

Have you made the filter.py file executable?

chmod +x filter.py
